A single raceme at the top of the plant, usually floppy but flowers may become erect in sunnier locations. Individual flowers are ½ to ¾ inch across when fully open, have 4 white to pale pinkish petals and 6 yellow stamens. The 4 sepals at the base of the flower are green to purplish and paler around the edges.
Leaves and stem:
![[photo of leaves]](/udata/r9ndp23q/white/cutleaf-toothwort_0425_102227.jpg)
All plants have basal leaves; flowering plants also have a single whorl of 3 leaves on the upper stem. Basal and stem leaves are similar, to 3 inches long and wide, palmately lobed, divided nearly to the base of the leaf into 3 to 5 main parts. Lobes are generally elliptical, coarsely toothed with large rounded teeth or additional small lobes and long leaf stalks. Leaves are hairless but the stem may be hairy in the upper part. Basal leaves are separated from the flowering stem.
Notes:
One of the early spring woodland bloomers.

I saw many of these in Maple Plain, Minnesota yesterday (04.12.10) in the Baker Park Reserve. They were right off the road in the maple/basswood forest. Use extreme caution if looking...there are several ephemerials blooming including wild leeks, wild ginger, and bloodroot. They are fragile. First time I have ever seen them!

There is a good amount of them off the trail in Three Rivers Park in Prior Lake so on to be developed. They are now not in full bloom. Hopefully when they develop the park they will not disturb them. There were masses of them and they are off the trail. Such a beautiful sight.

04/16/16... While birding for Yellow-headed blackbirds near Swan Lake a few miles northeast of Nicollet, we followed a gravel 'public access' road through the swamps, came upon a small hardwood forest. Without stepping out of the car, one could observe the ephemerals spread across the shaded floor of the forest. After 75 years in the woodlands, this was our first encounter with the beautiful plant.

Was walking with my wife in Carver Park Reserve and observed many colonies in full bloom in wooded area (before we were told to "Get Out!" by nesting bald eagles).

Carpeting the woodland floor on the east side of Middle Lake 1 mile NE of Nicollet. Perhaps it's not supposed to be eaten, but it has a very pleasant, subtle brassica flavor. (04/20/2021)

These were blooming in partly shaded areas near the walking trail in Keller Woods near Circle Pines on May 1.
