Pygmy Peashrub

Caragana pygmaea, commonly called Pygmy Peashrub, is a compact, deciduous shrub with small yellow, pea-shaped flowers and fine green leaflets. Its multi-stemmed form grows upright before arching, and it can be used as a low informal hedge. Published size estimates vary, so allow room for a broad mature outline. ## Form and flowering [Oregon State University](https://landscapeplants.oregonstate.edu/plants/caragana-pygmaea) describes a compact, spreading shrub about 5 feet tall and wide, with spring flowers and USDA hardiness to zone 3. [Utah State University](https://extension.usu.edu/cwel/research/selection-and-culture-of-landscape-plants-in-utah) lists a smaller garden size of 2–3 feet tall by 4–5 feet wide. The differences reflect distinct regional references; the plant's mature size depends on site and growing conditions. ## Placement Choose a sunny site with room for the branches to arch. Oregon State reports that the species tolerates wind and dry sites and is often planted as a hedge in the upper Midwest. Its compact scale also suits a shrub border where a low, broad form is useful. ## Maintenance Water while new roots establish, then adjust irrigation to local rainfall and soil. Avoid prolonged saturation. Allow the shrub to keep its natural outline, removing damaged or badly placed branches as needed.
