The Arboretum is home to a number of spectacular climbing hydrangea species, including nine specimens of the liana (woody vine) Hydrangea anomala, such as the one pictured above in Rhododendron Glen. Some specimens date all the way back to the beginnings of the Arboretum and reach up to 80 feet high, usually climbing up tall Douglas fir from the native matrix.
Bloom time varies from late spring to late summer, depending on the species. In the latest issue of the Arboretum Bulletin, editor Niall Dunne profiles the main deciduous and evergreen species and tells you where to find them.
