The flower of Hydrangea paniculata ‘Bulk’, also known as Quick Fire, are one of the earliest to emerge of this species and turn an attractive pinkish-red.
For those that like their hydrangeas they may want to consider H. paniculata 'Bulk', also known as Quick Fire Hydrangea.
Quick Fire flowers several weeks earlier than other H. paniculata. Yes, the blooms start out as white just like the other cultivars and yes, they turn reddish pink as we move into late July and August. But because Quick Fire blooms earlier, its flowers are turning color while the other hydrangea flowers are still white. It is a nice contrast of white flowers in the landscape to Quick Fire's reddish-pink flowers.
Just like other cultivars of H. paniculata, Quick Fire is relatively easy to grow. Avoid swampy or very wet areas as it prefers moist well drained soils. It will grow well within every growing region of Pennsylvania has it's hardiness goes to about a zone 3. It can withstand some shade but I have seen it grow best in sunny locations.
H. paniculata 'Bulk' can reach spread and height up to 8 feet. Pruning can be done as late as February or early March as flowers are produced on new growth. Not all hydrangea should be pruned at the same time. If you prune H. quercifolia or H. macrophylla at the time of H. paniculata, you are removing the upcoming year's flowers.
