Exochorda is a little-known monotypic genus in the rose family. The single species E. racemosa is divided into 4 subspecies, ranging primarily from southeastern China, with a disjunct population in the “Stans” (Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan).
Exochorda is a small shrub that flowers for us in late winter, usually starting around March 1. Pictured below in our garden is Tom Ranney’s relative new hybrid, Exochora ‘Blizzard’, which we absolutely love. This should mature around 6′ tall x 7′ wide. Zone 4a-8b.
