Plant Taxonomy of Witch Hazel:
classifies the witch hazel with which I deal here as Hamamelis x intermedia
'Arnold Promise.' The cultivar
name is sometimes misspelled 'Arnold's Promise.' This type of witch hazel is a hybrid plant
, being a cross between Hamamelis japonica
(Japanese witch hazel) and Hamamelis mollis
(Chinese witch hazel).
Arnold Promise witch hazel plants are usually treated as deciduous
flowering shrubs. However, you will often hear witch hazels referred to as witch hazel "trees" because, if left unpruned, they can grow rather tall.
Characteristics of Witch Hazel Shrubs:
Arnold Promise witch hazel plants are vase-shaped and may reach heights of 12 feet or more with a similar spread, although they can easily be kept much shorter via pruning. Fall foliage is yellow. The flowers bear a warm, spicy fragrance and precede the leaves, blooming in late winter to early spring. The fringe-like petals on these yellow flowers
resemble small strips of paper that have just exited from a shredder. From a distance, one could mistake witch hazel plants for forsythia
(another early bloomer with yellow flowers). In fact, as with forsythia, people sometimes force the flowers
of witch hazel plants.
Planting Zones for Witch Hazel Shrubs:
Sun and Soil Requirements for Witch Hazel Shrubs:
Grow witch hazel plants in full sun to partial shade and in a well-drained, acidic soil
amended with humus
. Understory trees in the wild, witch hazel plants are suitable for woodland gardens
, although you'll sacrifice some blooms if you don't grow your witch hazel plants in full sun.
Outstanding Feature of Witch Hazel Shrubs:
Perhaps more important than the beauty of Arnold Promise witch hazel's floral display is its timing
: blooming so brightly as it does in March (zone 5) when the landscape is generally still in its dull winter doldrums, this bush is a must-have for the four season landscape
Uses in Landscaping:
Witch hazel plants are showy enough when in bloom to serve as minor specimen plants
. I say "minor" only because, during spring (after blooming is finished) and summer, the bushes are rather ordinary-looking (although the vase-shaped form
will be valued in winter by those who appreciate subtleties). Mix them into a bed of other deciduous bushes, situated within sight of a window. That way, you can enjoy an unimpeded view of these beauties in late winter to early spring (all you'll see is an eruption of yellow in the midst of a forest of bare branches!).
Pruning and Other Care for Witch Hazel Shrubs:
Prune Arnold Promise witch hazel plants after they flower in spring. For winter protection and to shade the roots from summer's heat, mulch
around your bushes.
Other Types of Witch Hazel and Meaning of the Name:
Eastern North America has an indigenous witch hazel tree, Hamamelis virginiana, or "common" witch hazel. The medicinal benefits of the bark of these witch hazel trees are well known through the "witch hazel" liquid we buy at pharmacies to use as an astringent. Unlike its Asian cousins and their hybrid, Arnold Promise, common witch hazel trees bloom in fall. But a second type of witch hazel, Hamamelis vernalis, or "vernal" witch hazel is also found in North America, in the southern part of common witch hazel's range. As its name suggests, vernal witch hazel trees bloom in spring.
European settlers in the New World used the branches of witch hazel trees as divining rods for dowsing, which is the basis for one of the explanations as to how witch hazel trees received the "witch" part of their name.
For the name ultimately derives from the Anglo-Saxon wych, meaning "bend" -- which is just what a divining rod is supposed to do when it detects water. But religious leaders had given dowsing such a bad name over the years that it was apparently easy to corrupt the name into "witch" (another name for divining is "water witching").
Witch hazel is sometimes spelled with a hyphen ("witch-hazel") to indicate that it is not a true hazel. Corylus is the genus name of true hazels.
So why the reference to "hazel" in the name, if it's not a true one? For one thing, the hazel had been one of the trees used in Europe for dowsing. In addition, the bush's namers may have found a resemblance to the leaves of the true hazels, such as contorted hazelnut.
