Nursery contributed plant descriptions

A Robin Hill hybrid, Congo produces large rich purple flowers over an extended period beginning in mid spring on a naturally dwarf and compact slow growing spreading to mounding plant. The long flowering season and compact habit make this an easy choice for bonsai culture and where a low maintenance evergreen is needed in the landscape. Provide a well-drained, moist, humus rich, acid soil for the best results.
