Comments This species can be damaged by wind and it needs support from companion plants. Seedlings are slow to mature, taking up to first years to bloom. Flowers are more showy on dry sites. Like other members of the pea family, this plant requires the presense of microorganisms which inhabit nodules on the plant's root system and produce nitrogen compounds necessary for the plant's survival. Soil/seed inoculum is available at most native plant nurseries.
