This is the third segment of our Ornamental Tree and Shrub Series….
Here is a darling understory shrub with a height of 3 – 6’ and equal width. When I first noticed this plant in the dappled light of my woodland, I was love struck. This is a native plant that is found in the eastern half of North America. The multi branched broad shrub is covered with light green 3” oval shaped leaves. This is a very well behaved shrub. In the shade the plant seems to be reaching for the sun and is thinner than the specimens located in full sun, which tend to be full rounded shrubs. I like to hike along the southeast base of Mt. Hoar on the edge of Lake Willoughby, Vermont, the understory is dense with Leatherwood. I am amazed at the width of the leaves, which seem much larger than the standard.
You cannot go wrong with a plant that is good in both sun and shade. It does enjoy moist soil, hence the species “palustris” which means “of the swamps”. The texture is of medium quality and it is slow growing. This makes a fine plant for the landscape, although it is very difficult to find in cultivation. This makes me covetous. Fall brings forth a fine clear yellow in the leaf, with best color in partial shade conditions.
Leatherwood has no enemies to speak of. Even deer won’t browse it (it is thought to possibly have diuretic qualities). Studies recently done show that extracts from the seeds contain linoleic and oleic acid which have insecticidal qualities for specific insects.
The bark has a leathery feel. It is not easy to snap off a branch. This quality made it useful for Native Americans to make baskets, bowstrings and fish lines. In very early spring, the shrub bursts forth with lovely perfect 4” butter yellow flowers. Each flower produces one seed. The large green seeds form and drop quickly, literally within a week all seeds will drop from the plant. The seeds need to be collected and sown fresh in late spring for sprouting the following spring. Layering works as a method, but proves difficult as one would have to work in the woodland laboratory where anything can happen. Propagation from cuttings is very difficult, which of course baits me – making it a must try!
