Hydrangea seemanii x serratifolia

Wow. Huge balloon shaped white flowers on this self-clinging, evergreen hydrangea. What more could you ask for?  This hybrid by Martin Grantham of San Francisco grows quickly to 20 ft or more. Half sun/morning sun is best with regular summer water. Frost hardy in USDA zone 8 with protection from most severe cold.
