Ever wish you could cover everything with flowers? When you plant a climbing hydrangea. that’s what happens! Unlike all of its hydrangea cousins. climbing hydrangea naturally grows as a vine which produces small rootlets that help it cling. In nature. it would clamor up trees and shrubs. and it’s still lovely that way in gardens. though its equally useful grown on walls. chimneys. fences. pergolas. and other structures.?
Climbing hydrangeas take a few years to get established before they begin to flower. but once they’re settled in and growing vigorously. they provide years of beauty. growing more dramatic and floriferous each season.?
