Winter Blooming Witch Hazel

Early Bird

One of my favorite winter bloomers is witch hazel, a small shrub-like tree.  The flowers themselves are only a few inches, but their unique shape and ability to cover dark, bare stems with flashes of color add excitement in winter gardens. The flowers are really clusters of four petals shaped like thin ribbons emanating from a dark, leathery base called a calyx. Depending on the cultivar, these one-inch to two-inch long ribbons are translucent yellow or mustard yellow, red/orange or brown/orange, or scarlet red or rust red. On warm winter days, the ribbons unfurl. As temperatures drop, the ribbons curl back as a protective mechanism against the cold.

Witch hazels are about 15 to 18 feet tall and wide, with wavy-edged, hazel-like leaves. In the fall, the leaves turn a striking yellow, sometimes with orange or red tinges, before dropping to reveal an open vase structure.

There are many Hamamelis species but the common ones are: Hamamelis japonica (Japanese witch hazel); H. mollis (Chinese witch hazel); H. vernalis (Ozark witch hazel); and H. virginiana (common or Virginia witch hazel). The first three are hardy to zone 4 or 5 while the last is hardy to zone 3. Common witch hazel is known for its use as an astringent in cosmetics. Hamamelis x intermedia is a cross between H. japonica and H. mollis – many cultivars have been bred from this to extend the flower color range as well as fall color of leaves.

Witch hazels like well-drained but evenly moist soil. They are forest understory plants, small enough for suburban properties but possibly requiring shade from the summer sun unless one can guarantee against drought. Usually they are not troubled by pests or diseases.

Witch hazels plants are easy to find at local nurseries in the spring but now is the time to view them in gardens in order to select your favorite flower color.  In Alexandria, Virginia, Green Spring Gardens has more than 200 Hamamelis plants. Green Spring Gardens’ witch hazel collection became an official Plant Collections Network (PCN) collection in 2006. PCN, a part of the American Public Gardens Association, is a network of botanical gardens and arboreta that coordinate preservation of germplasm. Member gardens make the germplasm available for studies, evaluation, breeding, and research. While Green Spring Gardens has the most extensive collection in the Washington DC area, you also can see them in bloom in other public gardens such as Brookside Gardens in Wheaton, Maryland, and the U.S. National Arboretum in Washington DC. Check out these perfect plants for the winter garden today so you can add few to your own garden this summer.

Now is the Time to Plant Native Trees!

Fringe Tree (Chionanthus virginiana)

To increase awareness of the importance of native trees, the Plant NOVA Trees website has a page dedicated to “October is Native Trees Month.” The site lists garden centers offering discounts on native trees, shrubs, and perennials; tree giveaways; and tree-related events in October. Now is your chance to plant native trees while saving money!

The Plant NOVA Trees campaign is part of the Plant NOVA Natives campaign to promote native plants in Northern Virginia. (Hint: bookmark these as they also list native plant sales). Plant NOVA Natives is one of 9 regional campaigns with the Plant Virginia Natives in the commonwealth.

Fall is an excellent time to plant hardy perennials, shrubs, and trees. The cooler temperatures, increased moisture, and decreased sun/heat allow the plants to settle in the ground, send out roots, and get established before winter. While the soil is still warm, roots continue to develop until the ground freezes so the plant’s energy is devoted to getting firmly settled in the soil, not developing new top growth. The plants you buy now can be planted with minimal stress to them and often, with minimal stress to your wallet as many garden centers discount plants to move the inventory before winter.

Native Fringe Tree with Showy Spring Flowers

If you live in the Washington DC metro area, you may be seeing fringe trees blooming now — its wispy cream flowers, like an old man’s beard, swaying in the breeze. Fringe trees (Chionanthus virginicus) are native, deciduous trees that prefer full sun to part shade and moist fertile soil. Their natural habitats are damp woodlands. Fringe trees are named after their sweetly scented flowers, comprised of 4 to 6 one-inch long straps. Although fringe trees are dioecious (male and female plants), they both flower. Some produce what are called “perfect” flowers (having both male and female parts). Therefore, female flowers and perfect flowers produce fruit that resemble dark blue olives. Fringe trees belong to the olive family and the birds love the fruit. These slow growing trees mature around 15 to 20 feet and are perfect for the home as specimen trees.

 

Beware the Bradford Pear Tree!

Spring is in the air and so is the white flowering Bradford pear (Pyrus calleryana). You have probably seen tons of them in the Washington DC metro area. Right now in March, they are really pretty with so many small white flowers – like puffs of white clouds. But then you begin to see them everywhere: along the highway, in vacated lots, and in every industrial park – like weeds.

The Bradford pear was originally thought to be a sterile tree. As new cultivars were created, the cultivars were able to cross pollinate, resulting in small fruit favored by birds (thus spreading the seed). As time has gone by and the trees have matured, we have learned that they are structurally weak. They develop such a steep V-shaped branching structure, they can easily split in half.

In addition to their invasive nature and their ability to break, the white blossoms have a foul, fish-like odor. If you stand near them in full bloom, the odor is very strong! Fortunately this goes away when the blooming season is over in the spring.

Contrary to the name, there are no “pear” fruit on the tree. This is an ornamental tree, not a fruit tree. But of all the ornamental trees you can plant on your property, this is probably the worst choice. There are so many other better choices, including native trees, that you should not even consider this one. And if you just purchased a home that has been landscaped with a small Bradford pear, pull it out immediately!

Support National Pollinator Week: Plant a Tree

sweet bay magnolia blooms in summer

This week is National Pollinator Week. It is amazing that something as small as a bee is vitally important to our food supply. As pollinators, bees transfer pollen thus ensuring that plants and crops develop fruit and seeds for us to consume. But bees are not the only keystone species that we depend on, we also need other pollinators such as butterflies, moths, beetles, flies, and birds, including hummingbirds. Continue reading
