Hydrangea paniculata 'Phantom'
Plant it in a spacious spot where its grandeur can be appreciated, like in an open corner of the garden or in its own specimen planting. displays exceptional cold hardiness. 'Phantom' swiftly assumes its mature size of 6 to 10 feet tall if unpruned. The only maintenance recommended is a severe annual pruning in March, taking the plant back down to just about 1 foot tall. This will keep it more compact (reaching about 4 feet tall each year) and will encourage the largest possible blooms.
