At first glance this lovely legume looks like a yellow form of Baptisia. A species with attractive, bright green foliage and long spikes of Lupine-like flowers in soft yellow that appear in June–July. Blends well with any color. Plant it at the back of the border.
Showy species of North America and Asiatic origin make up this genus, but only a few are used decoratively in the garden. They make excellent border plants in full sun and average soil.

HOW PLANTS ARE SHIPPED
The size of the plants we ship has been selected to reduce the shock of transplanting. For some, this means a large, bareroot crown. Others cannot travel bareroot or transplant best if grown in containers. We ship these perennials and annuals in 1 pint pots, except as noted. We must point out that many perennials will not bloom the first year after planting, but will the following year, amply rewarding your patience. We ship bulbs as dormant, bare bulbs, sometimes with some wood shavings or moss. Shrubs, Roses, vines, and other woody plants may be shipped bareroot or in pots. The size of the pot is noted in the quick facts for each item.

Latin Name Pronunciation: ther-mop'-sis
Thermopsis' flowers are borne in pea-like spires on erect stems with three-lobed leaves. Grow in average, well-drained soil. Fertilize just once, in early spring, with a granular, balanced fertilizer such as 10-10-10.
It’s also best to choose a permanent location when planting Thermopsis, as its roots resent disturbance once established.
