('ILVOBO') At last a hardy DWARF Hydrangea! Beginning in July, BOBO is engulfed by large white flowers on strong stems. These gradually turn pinkish in the fall. Many a space-challenged gardener has planted a young Hydrangea paniculata and only later discovered that once it matures it is too big to fit their garden. This is a shame because Hydrangea paniculata are really hardy (zone 3) and lovely shrubs. BOBO is a compact 75-90cm (2.5-3') tall and 1.2m (4') wide.
