Caragana microphylla

Caragana is a genus of about 80–100 species of flowering plants in the family Fabaceae, native to Asia and eastern Europe. They are shrubs or small trees growing 1–6 m (3.3–19.7 ft) tall. They have even-pinnate leaves with small leaflets, and solitary or clustered mostly yellow (rarely white or pink) flowers and bearing seeds in a linear pod. Caragana species are used as food plants by the larvae of some Lepidoptera species including dark dagger.
