To ask which of my plants is my favorite is like asking which of my children is my fave! A difficult topic to answer, but since I’m not in danger of hurting sensitive young egos, I’d have to say the oakleaf hydrangea is one of my favorites (Hydrangea quercifolia). The reason for this is that this is a plant that has four distinct seasons of appeal. That appeals to me since it saves me time, energy, and money. It rewards me in the spring, summer, fall, and winter once it has established.
Hydrangea quercifolia is a shrub that grows to be around six to eight feet tall, with a maximum height of ten to twelve feet. The huge, dark green leaves have silvery undersides and resemble the Northern Red Oak, from which it receives its popular name. It can be grown in zones 5 through 9.
Cone-shaped flowers can grow up to a foot in length. The blossoms start out white, then acquire a pink blush before turning red as the seasons pass. Single or double florets might be found.
Although the spring and summer are lovely and lush, I am looking forward to the warm days and cool nights of October and November, when the flowers change red and the foliage takes on a variety of yellow, orange, red, brown, and burgundy hues. In protected areas, the leaves last for a long time before falling to reveal an uneven branching structure of cinnamon-colored peeling bark. The contrast against a snowy white bedspread is breathtaking.
Oakleaf hydrangeas thrive in hotter climates, but they like some afternoon shade. It can be grown in full sun in its northern range. The more sun exposure you get, the more flowers you’ll receive, and the more stunning the fall color will be.
This shrub can survive drier soil than its mophead relatives, but not wet feet. Plant it in acidic, wet, well-drained soil supplemented with compost or other organic matter. It can be used as a specimen feature in the landscape or as a mass planting in shaded wooded regions.
Pruning is rarely essential, although it should be done after the flowers have faded and before August. Late summer and early fall are the best times to plant flower buds for the next year. By simply snipping off old flowers, you can “deadhead” them at any time. I like to leave the blossoms on the plant throughout the winter months so that I may enjoy them.
You can cut longer stems for flower arrangements before August if you’re cutting blossoms for arrangements. After that, only remove short stems to avoid losing next year’s blooms.
Oakleaf hydrangeas are generally pest and disease free. This is another bonus in my eyes because it means that plants will look and perform their best all year long without the need of chemicals (always a last resort in my book).
The double flowered variety ‘Snowflake’ is arguably the most popular. Its creamy white blossoms can reach a length of a foot.
In the spring, the foliage of ‘Little Honey’ turns golden, then chartreuse, then green, with a gorgeous burgundy red fall color.
Oakleaf hydrangeas are a perennial favorite in my yard. They’re lovely all year with stunning leaves, exquisite flowers, and fascinating bark, and they’re hardy in many regions of the country. They’re pest and disease resistant, bloom in the shade, and are very little maintenance. What more could we expect of a plant for our landscapes and gardens?
