The Hydrangea paniculata produce those lovely cone shaped flowers that we enjoy all summer. Paniculata's form flowers on the current season's wood, so spring pruning won't hurt the summer's show. 'Bobo' is a wonderful small version. At no larger than 36"/90cm, the strong, sturdy stems produce large white flowers. As blooms age, they turn pink. New stems can produce new flowers as long as the season continues.
