Taxonomy
Cultivation
Name
- How does the scientific name, Hydrangea quercifolia break down, exactly? Well, we are all familiar with the Greek root hydr- as a reference to water, as in \"hydrate.\" Meanwhile, angeon comes from the Greek for \"vessel.\" Some people apparently see a resemblance between a hydrangea seed pod and a water vessel. Most species do require a lot of watering (oakleaf hydrangeas ofte…
Appearance
- In summer, Snow Queen oakleaf hydrangea flowers in clusters, and the white flowers fade to a pinkish-brown in fall. Their floral display is very long-lasting. But the plant's best-known trait is its oak-leaf-shaped foliage. The leathery leaves are large and turn purple, orangey-bronze, or red in the fall, making the plant a great pick for autumn color.
Morphology
- Snow Queen shrubs typically reach a height of 4 to 6 feet and a similar spread, but they can grow to be larger than that. They are multi-stemmed shrubs, and the branches can shoot out from the center in any direction. Peeling bark on the branches offers some winter interest, as well as spring interest. Before the plant fully leafs out in the spring, it offers little visual interest other than the b…
Culture
- Oakleaf hydrangea shrubs are understory plants in the wild. In southern climates, give them afternoon shade. In the North, oakleaf hydrangeas can get by with less shade. Too much shade, in fact, may reduce the intensity of their fall-foliage color. Grow them in a well-drained soil with a slightly acidic soil pH and plenty of compost. The more sunli...
Treatment
- But sometimes, even if you have chosen the right location for the bush, you may be forced into pruning it. For example, you should prune if the plant suffers damage (such as from winter die-back). In this case, wait until spring, then cut the affected branches down to just below the damaged areas.
Management
- If you do wish to prune to control the plant's size and/or shape, do so right after the blooming period since this type of bush blooms on old wood. Mulch your bushes to keep the roots cool in summer, especially in hot regions.
Reproduction
- Technically speaking, the floral display on oakleaf hydrangea comes from sepals rather than flower petals. Sepals are like petals, but they are sterile. Since they can't be pollinated, they can't go to seed. Playing no part in the reproduction process, they are free to just \"hang out\" and give your yard color all summer long. The true flowers on oakleaf hydrangeas are the tiny ones that y…
Uses
- With their brilliant fall foliage and long blooming period, oakleaf hydrangea shrubs are attractive enough to function as specimen plants. As understory shrubs in the wild, they are also appropriate in woodland gardens. Their big leaves give them a coarse plant texture, providing contrast with plants of a more delicate texture. Their flowers can be dried for use in crafts, while the fresh one…
