Members of the Synthyris genus are low growing hardy perennials that reach from 6 to 30 cm ( 3 to 12 inches) in height. This makes them great for growing in rock gardens.
They often bloom twice a year, always in early spring, and sometimes in autumn.
When they bloom, Synthyris carry spikes of small white, purple, blue, or pink flowers.
