Gardeners' Notes:

This less known cousin to Large flowered bellwort are becoming more common in the nursery trade. It may seem to have a lot in common with Large flowered bellwort but its growing habit is different. While large flowered bellwort stays in a tight clump, Sessile Bellwort (I dislike the word Wild Oats) spread with long rhizomes in a evenly spaced area, almost like a ground cover. Another common name is Sessile - leaved bellwort because it have no petioles or stalk that connect it to the stem. (Not to be confused with a third species of bellwort, Perfoliate Bellwort, which is not hardy here in Minnesota)

Is zone 3b hardy

Smaller than U. grandiflora, these have dainty yellow flowers that droop gracefully above the foliage. The flowers are followed by three-cornered green seed capsules. They thrive in areas with deep leafmould and high shade, such as from deciduous trees.

The plants should be divided every few years, and will readily form new colonies within a few seasons after being moved. Mulch generously with rotted straw, marsh hay, or old leaves.
