What these mean
Find
1 Everywhere · 2 Common in the right habitat · 3 Patchy · 4 Elusive. This is about how much there is, not whether you may pick it. It is based on iNaturalist sightings within 25 km (about 15 miles) of downtown DC, counted on October 3, 2026. The four rules that each plant’s “Find” reason refers to: (A) the estimate is the confirmed sightings, plus the unconfirmed ones (scaled down where the plant has lookalikes in its genus), plus the sightings marked as planted; (B) the tier by estimate: 1,500 or more is tier 1, 250–1,499 tier 2, 50–249 tier 3, under 50 tier 4; (C) tier 1, Everywhere, also needs a source saying the plant is common in lawns, sidewalks, yards or gardens, vacant lots or towns, or at least one DC street tree of it per km of sidewalk, otherwise it is tier 2; (D) if a reliable source says the plant is rare in this region, or that wild plants rarely bear the harvest, only planted sightings count. iNaturalist is a website and phone app where people post photos of the plants and animals they see. A sighting is “research grade” when other users have confirmed what it is; “needs ID” sightings are not confirmed yet, and “cultivated” ones are marked as planted.
Effort
1 Grab & eat · 2 Quick kitchen prep (under about 30 minutes) · 3 Real work (hours, or cooking needed for safety) · 4 Project (days or equipment). Scored on the simplest worthwhile use; each plant’s page says why.
ID risk
How hard it is to harvest safely. Beginner: no dangerous lookalike, and the edible part is not easily confused with a toxic part. Careful: a toxic lookalike, or toxic parts that end up in the harvest unless removed (for example elderberry stems, unripe ground cherries), or other parts of the plant rated medium-or-higher toxicity, with reliable features to separate them. Expert only: a potentially deadly lookalike that is hard to separate, or (for not-recommended harvests like pokeweed) a plant whose safe preparation can’t be guaranteed. Toxic parts that are obviously separate and thrown away anyway (pits, seeds, skins) don’t raise it; the Toxic parts mark carries that warning.
Native or not, and the invader stars
Origin is where the plant comes from: native, non-native, or mixed (the harvest covers both). The stars rate plants on invasive plant lists: ★★★ Virginia DCR “High” or Maryland prohibited invasive · ★★ Virginia “Medium” · ★ Virginia “Low” · ☆ listed only by the Maryland Invasive Species Council or the Mid-Atlantic Plant Invaders guide (advisory) · no stars: native or not listed.
Safety marks and flags
Deadly lookalike / Toxic lookalike: a cited source names a lookalike of that danger, recorded near DC (an iNaturalist sighting within 25 km, a DC street tree, or a Smithsonian listing for DC) and looking like the part you eat. Other lookalikes are still listed, marked “not recorded near DC” or as not looking like the part you eat. Deadly means a source says eating it may be fatal or calls it deadly, or NC State rates it high severity with life-threatening symptoms (sources sometimes disagree; for example Virginia creeper). Each plant’s Lookalikes list says how to tell them apart; “harmless (may be edible)” lookalikes are listed so you know a mix-up isn’t dangerous. Cook first: cooking is needed for safety (for daylilies it is a precaution, not a sourced requirement). Eat in moderation: a source says to limit quantity or frequency (for example oxalates in sorrels and dock, ginkgotoxin, safrole). Spray risk: a source says the plant is commonly treated with herbicide in parks or lawns (invasive control, lawn weeds) or, for ginkgo, sprayed to stop fruiting. Contamination: a source says the plant concentrates pollutants. Each plant’s Safety flags list gives the details and sources.
Seasons
Start, peak and end are given in thirds of a month: early, mid or late. A plant counts as in season for a month if it is in season at any point in that month. Some greens and roots have a second window, in spring or fall; their page shows each window. A season that runs across New Year is shown as one window.
What it looks like
A native woodland wildflower of the barberry family, 1 to 1.5 feet tall, that spreads by underground stems into dense colonies (NC State). Plants with a single umbrella-like leaf do not flower; plants with two leaves bear one nodding white flower in the fork between them in April or May (NC State; Prince William Wildflower Society). The fruit is an egg-shaped berry 1.5 to 2 inches long, about the size of a small lemon (NC State; Wisconsin Extension), and the leaves tend to hide it (Eat The Weeds). It starts green, like a lime, and when ripe it is golden yellow, soft and a little wrinkled (Eat The Weeds; NC State). An uncommon pink-flowered form has maroon or red fruits (Wisconsin Extension). Inside are several tan seeds in the pulp (Wisconsin Extension). NC State calls the flavor lemon-like, and also bland, somewhat like an overripe melon; Eat The Weeds says some think it tastes like an earthy banana or pawpaw. Fruit set is often low (Prince William Wildflower Society), and squirrels, box turtles and other animals eat the fruit (NC State).
Safety
Every part of mayapple except the fully ripe fruit is highly poisonous, and its toxin is podophyllotoxin (NC State; Wisconsin Extension). NC State says the unripe fruit, roots, stems, seeds and leaves cause salivation, vomiting, diarrhea, headache, fever and, rarely, coma. The Lady Bird Johnson Wildflower Center calls the unripe fruit, leaves and roots highly toxic and possibly fatal if eaten, and Purdue Extension warns that eating mayapple can be quite dangerous, even fatal. A man who swallowed 'mandrake' bought at a health food store, almost certainly mayapple, was hospitalized overnight with severe nausea and vomiting (Archives of Internal Medicine, 1997). Eat only fruit that is fully yellow and soft (NC State); green fruit, which looks like a lime, is unripe and poisonous (Eat The Weeds; NC State). Remove every seed: NC State says the seeds are poisonous, and Purdue says the seeds inside the ripe flesh are toxic. Even ripe fruit is edible raw only in limited quantity (NC State; U.S. Geological Survey), and eating too much can act as a laxative (Eat The Weeds). Foraging Texas says to peel the fruit and eat only the inner flesh, because the rind is a strong laxative; Eat The Weeds says the soft white inner side of the peel is edible. Eat The Weeds warns not to eat mayapple when pregnant; podophyllin, a resin made from mayapple, must not be used on pregnant patients, because birth defects, fetal death and stillbirth have been reported after its use on the skin (Podocon-25 drug label). Wear gloves: NC State advises gloves for handling any part of the plant, because contact with the leaves or roots can cause severe redness, irritation and skin ulcers, especially to the eyes. Harmless lookalikes: NC State lists Indian cucumber-root and Canada waterleaf among plants often confused with mayapple. Indian cucumber-root has whorls of 5 to 9 and 3 leaves on a thin stem and berries that ripen dark bluish-black, and Canada waterleaf has maple-shaped leaves and tiny dry capsules with stiff black hairs; mayapple has umbrella-like leaves with the stalk attached near the middle and a single egg-shaped fruit (NC State). Avoid fruit from areas that may have been treated with pesticides (NC State).
Lookalikes
Indian cucumber-root Medeola virginiana harmless (may be edible)
NC State lists Indian cucumber-root among plants often confused with mayapple, and mayapple among plants confused with it. Indian cucumber-root has whorled leaves on a thin, hairy stem, a lower whorl of 5 to 9 leaves and an upper whorl of 3, and berries that ripen dark bluish-black in September and October; mayapple has one or two large umbrella-like leaves with the stalk attached near the middle and a single egg-shaped fruit 1.5 to 2 inches long that ripens golden yellow (NC State). NC State says its rootstalk may be eaten raw, but that eating it is no longer recommended because the plants are becoming scarce.

- Medeola virginiana (Indian Cucumber Root) NC State Extension Gardener Plant Toolbox
Canada waterleaf (broad-leaf waterleaf) Hydrophyllum canadense harmless (may be edible)
NC State lists Canada waterleaf among plants often confused with mayapple, and mayapple among plants confused with it. Canada waterleaf has maple-shaped leaves with 5 to 9 shallow lobes and alternate leaves on the stem, and its fruit is a tiny dry capsule (about 4 mm) with stiff black hairs; mayapple’s leaves are umbrella-like, with the stalk attached near the middle, and its fruit is a fleshy egg-shaped berry 1.5 to 2 inches long (NC State). NC State lists no poisonous parts for Canada waterleaf.

Safety flags
Eat in moderation
podophyllotoxin (in the seeds, unripe fruit and the rest of the plant): NC State says ripe (yellow and soft) fruit is edible raw but in limited quantity, and the U.S. Geological Survey’s plant guide repeats that limit. Eat The Weeds says overeating can act as a laxative, and Foraging Texas says the rind is a strong laxative, so peel the fruit and eat only the inner flesh.

Handling hazard (serious)
irritant sap/pulp: NC State advises gloves for handling any part of the plant: contact with the leaves or roots can cause severe redness, irritation and skin ulcers, especially to the eyes. Podophyllin, the resin made from mayapple, is a powerful caustic and severe irritant, and eye contact calls for a doctor or poison center (Podocon-25 drug label).

Toxic parts
The roots, leaves, stems, seeds and unripe fruit are highly poisonous (podophyllotoxin): salivation, vomiting, diarrhea, headache, fever and, rarely, coma (NC State); the Lady Bird Johnson Wildflower Center says they may be fatal if eaten. The seeds sit inside the edible fruit and must be removed (NC State; Purdue).

Safety marks and flags: what this means
Deadly lookalike / Toxic lookalike: a cited source names a lookalike of that danger, recorded near DC (an iNaturalist sighting within 25 km, a DC street tree, or a Smithsonian listing for DC) and looking like the part you eat. Other lookalikes are still listed, marked “not recorded near DC” or as not looking like the part you eat. Deadly means a source says eating it may be fatal or calls it deadly, or NC State rates it high severity with life-threatening symptoms (sources sometimes disagree; for example Virginia creeper). Each plant’s Lookalikes list says how to tell them apart; “harmless (may be edible)” lookalikes are listed so you know a mix-up isn’t dangerous.

Contamination: a source says the plant concentrates pollutants. Each plant’s Safety flags list gives the details and sources.
- ID risk
- Careful
- Why
- Every part except the fully ripe fruit is highly poisonous (NC State rates mayapple high severity), and the poisonous seeds are inside the fruit, so every seed must be removed. Pick only fruit that is golden yellow and soft: green, lime-like fruit is unripe and poisonous (NC State; Eat The Weeds). NC State lists Indian cucumber-root (whorled leaves, bluish-black berries) and Canada waterleaf (maple-shaped leaves, tiny dry bristly capsules) as plants often confused with mayapple; both grow near DC, but the likeness is in the leaves, and neither bears a fruit like mayapple’s single egg-shaped berry, so they do not raise the ID risk.
- Handling hazards
- Irritant sap/pulp (serious)
- Soil risk
- low
ID risk: what this means
How hard it is to harvest safely. Beginner: no dangerous lookalike, and the edible part is not easily confused with a toxic part. Careful: a toxic lookalike, or toxic parts that end up in the harvest unless removed (for example elderberry stems, unripe ground cherries), or other parts of the plant rated medium-or-higher toxicity, with reliable features to separate them. Expert only: a potentially deadly lookalike that is hard to separate, or (for not-recommended harvests like pokeweed) a plant whose safe preparation can’t be guaranteed. Toxic parts that are obviously separate and thrown away anyway (pits, seeds, skins) don’t raise it; the Toxic parts mark carries that warning.
Handling hazards: what this means
Stings, thorns, irritating or phototoxic sap, staining hulls and spiny husks, with a severity: minor = brief discomfort; moderate = rash or blisters lasting days; serious = burns, scarring or medical care possible.
Soil risk: what this means
Based on the part you eat, following the urban-soil lead guidance on the Field safety page: higher for greens, shoots and roots; moderate for flowers; low for fruit, nuts and sap.
Field safety for every outing (poison ivy, ticks, soil, and more)
When to pick
- Starts
- late Jul
- Peak
- early Aug–late Aug
- Ends
- late Sep
The Prince William Wildflower Society (Northern Virginia) says the fruit matures by August; NC State says to collect it in August or September, and Eat The Weeds gives July through September. Ripe fruit is golden yellow and soft (NC State), often when the rest of the plant is dying back (Eat The Weeds). Plants that are ripening fruit keep their leaves, while plants without fruit usually die back by early summer (Prince William Wildflower Society). Animals take ripe fruit quickly (Prince William Wildflower Society; NC State). No source gives DC dates, so the start and peak here are estimates.
How the dates were worked out
Every start, peak and end was re-checked in October 2026. “Sourced” means a source opened during the check states that timing for the DC or Mid-Atlantic area. “Estimated” means no source states it exactly; the reason, the evidence and the source links are under “How the dates were worked out” on each plant’s page. Peaks are often estimated, because few sources name a peak. iNaturalist evidence means research-grade sightings near DC, by month, of the plant at that stage (for example, in fruit). iNaturalist is a website and phone app where people post photos of the plants and animals they see. A sighting is “research grade” when other users have confirmed what it is; “needs ID” sightings are not confirmed yet, and “cultivated” ones are marked as planted.
Season basis: estimated: start, peak
Start
estimated: No source dates the start for the DC area to a third of a month. 'Matures by August' in Northern Virginia puts the first ripe fruit at the end of July; July is also the start of Eat The Weeds' range.
Peak
estimated: No source names a peak; August is the month both the Northern Virginia source and NC State include.
End
sourced
Evidence
start: Prince William Wildflower Society (Northern Virginia): 'The fruit matures by August'. Eat The Weeds: 'fruit available in late summer depending on climate, July through September'. iNaturalist (25 km of DC, research grade, fruiting annotation): 17 in July, 1 in August, 1 in September; the April to June records are flowers or young green fruit. | peak: Prince William Wildflower Society: 'The fruit matures by August'. NC State: 'HARVEST TIME: Collect in August or September.' | end: NC State (North Carolina): 'HARVEST TIME: Collect in August or September.' Eat The Weeds: 'July through September'.

Where to look
Rich, moist woods and stream valleys, where it grows in large colonies; logged most in Rock Creek Park, on the C&O Canal towpath (many at Carderock), at Huntley Meadows Park, in Glencarlyn Park and along Sligo Creek. Rock Creek Park and the county parks are look-only; the C&O Canal allows edible fruits generally but sets no limit for mayapple, so it is ambiguous there (ask the park). Picking is allowed in Virginia state parks such as Mason Neck and Leesylvania, or on private land with the owner’s permission. In late summer, look under plants that still have their leaves: plants ripening fruit keep them, while the rest die back by early summer (Prince William Wildflower Society).
- Habitats
- old fields & meadows, woods edges, trailsides & thickets, floodplain & stream-valley forest, upland oak-hickory woods
Habitats: what this means
Listed where the plant’s own sources place it in that habitat. “Disturbed ground & waste places” means a cited source places it on disturbed areas, sites, soil or ground, on waste places or waste ground, on construction or abandoned building sites (old home sites count), on rubble or in strip mines. When the source gives examples of the disturbed places, at least one example must be of that kind. Examples that do not count: natural or forestry disturbance (treefall gaps, fire, windthrow, flood scour, old riverbanks and creeks, clear-cuts); roadsides, railroads and rights-of-way; and abandoned fields, pastures and farmland, which are “Old fields & meadows”. “Vacant lots” only where a source says vacant or empty lots.
Most-logged places
None of the most-logged places allows picking.
Ask first: rules unclear or not checked
- C&O Canal NHP (towpath, Georgetown to Great Falls MD and beyond)
Ambiguous: the C&O compendium allows edible fruits, nuts and berries generally but sets no limit for this one; ask the park first. Of these, 62 are at Carderock.
No picking here (4 places)
- Rock Creek Park
Look but don’t pick: Rock Creek Park’s compendium bans gathering any fruit, nut, berry, seed or greenery.
- Huntley Meadows Park
Look but don’t pick: Fairfax County parks ban removing any plant part without written permission.
- Glencarlyn Park
Look but don’t pick: Arlington County park rules say flora shall not be removed or disturbed.
- Sligo Creek Stream Valley Park
Look but don’t pick: Montgomery/Prince George’s parks (M-NCPPC) ban harvesting vegetation without a permit.
Most-logged places: what this means
The places with the most research-grade iNaturalist sightings within 25 km of downtown DC (re-counted in October 2026 over every named place, campuses, condominiums and private grounds included), each marked legal to pick or not. A sighting inside several named places counts once, for the smallest of them, but a sighting inside a National Park Service park never counts for a private, campus or unchecked place. iNaturalist shows where people walk and log plants, not true abundance. Private campuses, condominiums, museums, estates and utility land (Pepco’s power-line land near Sligo Creek) are marked “no” (pick only with the owner’s permission); public university campuses, city parks and other places whose picking rules were not checked (county stormwater land, the U.S. Capitol Grounds, Greenbelt’s North Woods, federal facilities such as the National Zoo) are “unknown”. A place needs at least 2 sightings, so plants with very few sightings have no places. At-risk plants (butternut, nannyberry, American chestnut, ramps, riverbank goldenrod) get places like every other plant; each page says why the plant is at risk and gives any advice its sources give. For some places, mostly Rock Creek Park, the iNaturalist map shows more sightings than the count here, because a map link cannot leave out exactly the sightings credited to another place. iNaturalist is a website and phone app where people post photos of the plants and animals they see. A sighting is “research grade” when other users have confirmed what it is; “needs ID” sightings are not confirmed yet, and “cultivated” ones are marked as planted.
Where you may pick
C&O Canal NHP’s compendium says edible fruits, nuts and berries may be gathered by hand for personal use but sets limits only for listed species; this one is not listed, so its status there is ambiguous: confirm with the park. Virginia state parks allow edible fruits, berries, fungi or nuts to be collected for personal or individual use (4VAC5-30-50). Not on Prince William Forest Park’s list. Rock Creek Park (which also runs Glover-Archbold, Battery Kemble, the western and northern Civil War Defenses forts and many small DC reservations) bans gathering any fruit, nut, berry or seed. Pick on private land only with the owner’s permission. Fruit set is often low, and the Eastern box turtle is thought to be the main disperser of the seeds (Prince William Wildflower Society); leave fruit for wildlife.
- Best legal spot
- Mason Neck State Park (34 obs)
- C&O Canal NHP (incl. Great Falls MD, trail-side only)
C&O 2026 compendium 2.1(c)(1): 'Edible fruits, nuts, berries, and mushrooms may be gathered by hand for personal use or consumption.' The limits table that follows does not list this species. 36 CFR 2.1(c)(1) requires designating 'certain' fruits, so the narrower reading (listed species only) is also possible. Confirm with the park.
- Virginia State Parks
4VAC5-30-50 bars gathering any plant without a permit, except that edible fruits, berries, fungi or nuts may be collected for personal or individual use; the fully ripe mayapple is an edible fruit
Where you may pick: what this means
For each park system: “yes” where its current rules (the park’s compendium or regulation) allow this plant or part, with the limit; “ambiguous” where the wording may or may not cover it, so ask the park; “no” where it is not allowed. Rock Creek Park, the GW Parkway sites (including Great Falls VA and Theodore Roosevelt Island), the National Mall, Montgomery and Prince George’s parks, Maryland state parks, and Fairfax and Arlington parks prohibit picking. Wolf Trap National Park for the Performing Arts allows blackberries and raspberries (one gallon per person per day) and chestnuts (one gallon per person per day). National Park Service rules are reissued every year; other parks change theirs from time to time, so check the park’s current rules. The Where you may pick page has every park’s rules.
Ways to use it
- eat the fully ripe flesh raw as a trail nibble, seeds removed and only a little at a time (Eat The Weeds; NC State)
- jelly, jam and marmalade (NC State; Eat The Weeds)
- a cold fruit punch: simmer the seeded fruit with ginger root, strain, sweeten, then top with ginger ale (Eat The Weeds)
- compotes, pies and a sauce like applesauce (Eat The Weeds)
- juice added to lemonade (Prince William Wildflower Society)
- harvest only fruit that is fully yellow and soft, often as the plants are dying back; green fruit is poisonous (NC State; Eat The Weeds)
Keeping
No source gives a storage time; seed the ripe fruit and freeze the pulp, or make jelly and keep it in the refrigerator or freezer, because there is no tested canning recipe.
- Use within
- within a few days
- Keeps fresh
- No source gives a storage time for ripe mayapples. Eat The Weeds says fruit picked just before it is ripe can be kept in sawdust until it ripens; eat or cook it only once it is fully yellow and soft (NC State).
- Canning
- no tested recipe: refrigerate or freeze, don’t can
- Keeping basis
- general guidance for its type
Ways to keep it
Freeze as researched: freeze pulp; canning: n/a (not shelf-canned)
Remove every seed and freeze the pulp; Eat The Weeds says mayapples freeze well. Pour fruit purée into containers or ice cube trays, leaving room for it to expand as it freezes (general guidance for fruit purée, University of Minnesota Extension).
Jam/jelly as researched: jam/jelly; canning: no tested recipe — refrigerate or freeze
Jelly, jam and marmalade are the traditional uses (NC State; Eat The Weeds). No tested canning recipe exists for mayapple, so keep jelly in the refrigerator or freezer. Do not seal jars with paraffin, as older recipes do: NCHFP says paraffin or wax seals are no longer recommended for any sweet spread.
Canning: what this means
Shelf-stable canning, three levels. Lab-tested: a lab-tested recipe from the National Center for Home Food Preservation (NCHFP) or Oregon State covers this fruit and product, or a generic recipe for its kind (the line says so, for example chokeberry). Extension recipe: a published Extension recipe (University of Alaska Fairbanks, written for Alaska species; University of Maine’s dandelion jelly), or a process that is safe only with a pH meter; follow it exactly, never improvise. No tested recipe: refrigerate or freeze, don’t can. “Hot-bottled syrup” = maple and walnut syrup, which keep when bottled hot at full syrup density. The Canning line names the exact product each source covers, for example “whole berries” or “juice”; a product not named there (such as juice from a berry with only a whole-berry recipe) has no tested recipe.
Keeping basis: what this means
“Specific to this plant” or “general guidance for its type” (for example NCHFP guidance for leafy greens applied to a wild green).
Nutrition
Not researched: in October 2026, only the calendar’s plants of the month and chicory leaves were researched.

Native or not, and the invader stars: what this means
Origin is where the plant comes from: native, non-native, or mixed (the harvest covers both). The stars rate plants on invasive plant lists: ★★★ Virginia DCR “High” or Maryland prohibited invasive · ★★ Virginia “Medium” · ★ Virginia “Low” · ☆ listed only by the Maryland Invasive Species Council or the Mid-Atlantic Plant Invaders guide (advisory) · no stars: native or not listed.
Virginia DCR, Virginia Invasive Plant Species List (effective September 2024), verbatim: "Under the DCR Invasive Species Assessment Protocol, approved by the Virginia Invasive Species Working Group, January 2024, species were ranked as exhibiting high, medium or low levels of invasiveness based on their threat to natural communities and native species. Invasiveness rank is higher for species that: • Alter ecosystem processes, such as succession, hydrology or fire regime. • Are capable of invading undisturbed natural communities. • Cause substantial impacts on rare or vulnerable species or natural communities or high-quality examples of more common communities. • Are found widely distributed and generally abundant where present. • Disperse readily to new areas. • Are difficult to control." The list also states: "The list is for educational purposes only and has no regulatory authority."
Maryland Department of Agriculture, Maryland Prohibited Invasive Plant Law and Regulations page, verbatim: "Plants on the Maryland Prohibited Invasive Plant List may not be added to stock after the effective date and should not be sold after their phase-out period ends."
No official DC invasive plant list was found.
How the ratings were set
- Find
- Common in the right habitat Estimate 5,616 = 5,550 research-grade iNaturalist sightings within 25 km + 66 'cultivated' (planted) sightings (rule A); that is tier 1 by count (rule B). Rule C: none of its sources says it is common in, or a weed of, an everyday place (lawns, sidewalks, yards or gardens, vacant lots, towns), so it cannot be tier 1 (Everywhere). Rule D does not apply: the Prince William Wildflower Society says "Fruit set rates are often low for individual colonies of plants and mature fruits are even rarer", but the Digital Atlas of the Virginia Flora, a source of greater standing about Virginia, calls mayapple "Common throughout." Final tier 2.
- Effort
- Grab & eat Pick only fully yellow, soft fruit, cut it open, take out every seed and eat a little of the flesh; jelly, jam or a fruit punch (simmer the seeded fruit, strain and sweeten) is extra kitchen work (Eat The Weeds; NC State).
Find: what this means
1 Everywhere · 2 Common in the right habitat · 3 Patchy · 4 Elusive. This is about how much there is, not whether you may pick it. It is based on iNaturalist sightings within 25 km (about 15 miles) of downtown DC, counted on October 3, 2026. The four rules that each plant’s “Find” reason refers to: (A) the estimate is the confirmed sightings, plus the unconfirmed ones (scaled down where the plant has lookalikes in its genus), plus the sightings marked as planted; (B) the tier by estimate: 1,500 or more is tier 1, 250–1,499 tier 2, 50–249 tier 3, under 50 tier 4; (C) tier 1, Everywhere, also needs a source saying the plant is common in lawns, sidewalks, yards or gardens, vacant lots or towns, or at least one DC street tree of it per km of sidewalk, otherwise it is tier 2; (D) if a reliable source says the plant is rare in this region, or that wild plants rarely bear the harvest, only planted sightings count. iNaturalist is a website and phone app where people post photos of the plants and animals they see. A sighting is “research grade” when other users have confirmed what it is; “needs ID” sightings are not confirmed yet, and “cultivated” ones are marked as planted.
Effort: what this means
1 Grab & eat · 2 Quick kitchen prep (under about 30 minutes) · 3 Real work (hours, or cooking needed for safety) · 4 Project (days or equipment). Scored on the simplest worthwhile use; each plant’s page says why.
