Detailed Information

Flower: Flower shape: 4-petals Cluster type: raceme

[photo of flowers] A single raceme of stalked flowers at the top of the plant, the flower stalks ascending to spreading to drooping, the flowers often nodding. Flowers are ½ to ¾ inch across when fully open, have 4 white to pale pinkish petals each 1 to 2 cm long, and 6 yellow stamens. The 4 sepals at the base of the flower are much shorter than the petals, green to purplish and paler around the edges. Sepals and flower stalks are hairless.

Leaves and stem: Leaf attachment: basal Leaf attachment: whorl Leaf type: compound Leaf type: lobed Leaf type: palmate

[photo of leaves] Leaves are basal, with flowering stems also having 2 or 3 stem leaves arranged oppositely (when 2) or whorled (3), though not all plants produce flowering stems. All leaves are similar, palmately compound with 3 leaflets, the leaflets mostly oblong-ellipitc in outline, to 3 inches (2.5 to 6 cm) long, usually with several large teeth or narrow lobes along the edges and commonly with larger lobes near the base so may appear to be 5 or more leaflets. Compound leaves are stalked, leaflets are stalkless. Leaves and stems are hairless though the upper stem may have sparse hairs.

Fruit: Fruit type: capsule/pod

[photo of fruit] Fruit is a straight, slender pod up to 1½ inches (2.5 to 3.8 cm) long, held ascending to spreading.

Notes:

Cutleaf Toothwort, known as Dentaria laciniata in some references, is one of our early spring woodland bloomers, found in moist deciduous woods in about half the state. Its leaves are pretty distinctive so is not likely to be confused with other species.

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)
