QUICKFIRE HYDRANGEA PRUNING FULL
Hydrangea paniculata 'Bobo'- (shown in the Natureworks gardens below) An excellent dwarf with large, full sized, white flowers in August that turn to pink in the fall. 'Little Quickfire' has the same flowers, growing only 3-5' tall and wide. The fall foliage is exceptional- deep maroon red and orange (shown below). Hydrangea paniculata 'Quickfire'- This variety blooms in late June with upright, open white panicles that quickly turn to rich pink. Ideal for dried flowers, wreaths, and arrangements. Hydrangea paniculata 'Vanilla Strawberry'- (shown at the top of this post) Giant, towering flowers of pure white open in late July, turning to bright pink in mid-August and finally deep strawberry pink in the cool fall weather. 'Little Lime' has the same flower power but grows 3-4' tall and 4-6' wide. This is a much sought after, full sized tree hydrangea that will grow 6-8' tall. The fresh flowers are sought after in the floral industry. Hydrangea paniculata 'Limelight'- (shown below) Large panicle flowers open a soft lime green in August, fading to soft pink in the fall. Here are a few of the most popular, newer varieties to showcase the wide diversity available. If you train the canopy up high enough you will eventually eliminate that problem! But panicle hydrangeas kept as low shrubs are just as susceptible to deer browse as all the other species. Do panicle hydrangeas get a lot of insect and disease pests? No. All hydrangeas need moisture in the soil in dry spells, but soggy soil that holds water for long periods of time will not work. Can panicle hydrangeas be planted in wet soil? No. Deep shade isn't good as they will become week and not have many flowers. They will grow just fine in partial shade. White, pink, deep rose, red, and lime green are their color palette. Can you change the color of their flowers by changing the acidity of the soil? NO. Always tie TO THE STAKE and then loosely loop around the trunk so the tree can move in the wind.ĭo panicle hydrangeas come in blue? NO. They are sold staked and, once planted, a thick, sturdy, tall oak stake should be added and the trunk should be tied in multiple places. Tree form hydrangeas cost more money because of the extra time and labor needed to produce them. After that, the top is pruned continuously until the crown reaches a saleable size. These are grown for many years at the nursery by selecting a single, strong, upright trunk, growing it up a stake until it reaches the desired height, then topping it to make it branch. Think of a lollipop and you will get the picture. The second form is called a "standard" or tree form. Occasional replacement trunks are allowed to grow up to keep the plant vigorous.
Then, the rounded top is thinned and pruned back each year. This is done by continuously removing the lower side branches (limbing up) until the canopy reaches the desired height. Others select out 3-5 of the strongest, upright growing stems and train them to be multi-stemmed, small trees. Some folks treat these as shrubs and cut the entire plant back very hard in early spring, keeping it short, full, and bushy. The shrub form is a plant that has multiple stems coming up out of the pot. Hydrangea paniculata plants can be purchased in two forms. Many have single flower panicles, with sterile flowers that attract pollinators. Some start out lime green instead of white and then turn to pink.
Others are early bloomers, flowering in June and going from white to red or pink in July. Some are dwarf, reaching a mere 2-3 feet tall and wide. Now, they are available in a mind boggling array of varieties. Panicle hydrangeas have come a LONG way since my early days of garden designing. The flowers can be cut fresh and immediately place in water or, once they have turned pink, can be cut, tied together, and hung upside down in a cool, dark place and be dried for fall and winter arrangements. paniculata 'Grandiflora' turns pink as the weather cools down, in late summer into early fall. Panicle hydrangeas have white flowers and H. Pruning is simple- cut as hard as you want every year in April. There are NO issues with this plant not blooming as the flowers are set up on new wood each spring. This species of hydrangea is totally hardy all the way up to Vermont, USDA hardiness zones 3-7. That stood for Hydrangea paniculata ' Grandiflora', the standard tree hydrangea in the industry.
When I was first designing gardens, we simply referred to them as Pee Gees. Hydrangea paniculata is a very old-fashioned plant that has been used in our gardens for centuries.
