Physaria acutifolia Rydb.
The silvery-gray rosettes of sharp-leaf twinpod bring cheerful yellow flowers to the late-spring garden; the plants are later ringed by their characteristic inflated seedpods (bladderpods). These short-lived plants reseed moderately but never crowd out their neighbors, ensuring a steady supply in the garden. Wyoming is home to more than 20 species of bladderpods (Physaria and Lesquerella spp.), many of which are garden-worthy. Plants are easy to propagate from seed.
