Detailed Information
Flower:
Stalked flowers in irregular flat clusters (umbels) 2 to 3 inches across, made up of 3 to 8 groups (umbellets) of 3 to 10 flowers each. Flowers are less than 1/8 inch across with 5 white petals that are usually curled up, and 5 stamens with creamy yellow tips. The flower stalks in an umbellet are varying lengths and there are no bracts at the base of an umbellet. A few clusters are at the top of the plant and at the end of branching stems in the upper plant.
Leaves and stem:
Leaves are compound in groups of 3. Leaflets near the base of the plant are largest, to 4 inches long and 2 inches wide on long stalks, the base of the stalk broadening to a light green sheath. Leaves become smaller and shorter stalked as they ascend the plant, with those near the flowers stalkless or nearly so. Leaflets are double toothed, with small teeth on the edges of larger teeth, have pointed tips, and taper abruptly at the base. The larger leaflets are often cleft or lobed in 2 or 3 parts. Stems are branched, light green and hairless.
Fruit:
Fruit is a 2-sectioned, ribbed seed, about ¼ inch long, pointed at the tip. It ripens from green to dark brown.
Notes:
There are some similar species in the carrot family that grow in the woods at about the same time. Aniseroot (Osmorhiza longistylis) and Sweet Cicely (Osmorhiza claytonii) both have larger flowers, distinct bracts at the base of an umbellet, hairy leaves and usually hairy stems. Honewort flowers typically stay curled up, has hairless double-toothed leaves, hairless stem, and no significant bracts at the base of an umbellet.

This plant just appeared in a shady spot near my garage in the Mpls neighborhood of Linden Hills. Thank you birds!

This seems to be an extremely aggressive seeder and it, and woodland nettle, are invading the maple/ash/basswood/hackberry woods that I cleared of buckthorn. Long, multifacted, dandelion like roots make it difficult to dig up. Taking over my shaded sedge meadow, among other wildflower areas.

This plant appeared last year and now 10 times as much. It pulls up easily, but wonder if I have the correct ID because it is so prolific. It is blooming now, July.

Growing in multiple areas of my property. The plants seem to grow with Great Nettle. Does anyone know of any uses for the plant?

I can't tell the difference between Cryptotaenia canadensis & Cryptotaenia japonica. I suspect I have both in my woods as My Korean Neighbor planted lots of Japanese Mitsuba which seems to have escaped. The plants look nearly identical, so much that I'm starting to think they may in fact be the same species.

Mike, we are unfamiliar with C. japonica. Efloras.org has a description of it, but I can find no key to the genus that includes both it and our native C. canadensis for comparison. I've only read that they are similar, which is not very helpful.
