Description

The words sino, meaning Chinese and 'jackia', referring to the Arnold Arboretum's John George Jack (1861-1949) along with honors to Alfred Rehder (1863-1949), a staff member of the Arnold Arboretum, Sinojackia rehderiana was developed.   

Hanging like a pendant, small white flowers appear in the springtime on cymes each having 3 to 5 flowers.  

Once established, it has some drought and heat tolerant. It blooms in late spring, followed by interesting-looking woody fruit. Afternoon shade should be provided in locations with hot summers.  

Its native habitat includes thick forest lands.  It prefers soil will a high organic content, but will tolerate a wide variety of soils as long as an acid pH and regular watering are provided.  Once established, with its roots penetrating the surrounding soils, it will tolerate dry soil and/or drought. Watering can then be reduced.  It is also heat tolerant, but afternoon shade is essential.
