Detailed Information

Flower: Flower shape: tubular

[photo of flowers] Clusters of 2 to 6 flowers (usually 3) arise from hairy buds on 1-year-old twigs, emerging before the leaves in early spring. Flowers are pale yellow, narrowly tubular with 4 shallow lobes, ¼ to 1/3 inch long. Protruding from the tube are 8 long, white stamens with yellow-orange tips and a slender, white style that elongates beyond the stamens. The hairy bud scales persist until the flowers fade.

Leaves and stems: Leaf attachment: alternate Leaf type: simple

[photo of leaf] Leaves are alternate, 1½ to 3 inches long, 1 to 2 inches wide, toothless, egg-shaped to oval to nearly diamond-shaped in outline, often widest above the middle, usually blunt at the tip, and stalkless to short-stalked. Surfaces are usually hairless, though the undersides may be woolly-hairy when young and a few hairs may persist especially along the veins.

[photo of twig and emerging bud] New twigs are mostly hairless, green turning red-brown to gray-brown the second year, and have distinctive enlarged nodes that form a flat ring around the bud and give the twig a jointed appearance. Twigs are very flexible and virtually unbreakable. Older bark on larger branches and the trunk is gray to brown, leathery, smooth or somewhat rough near the base. Stems are usually single, up to 3 inches diameter at the base, and many-branched from near the base with a crown about as wide as tall.

Fruit: Fruit type: capsule/pod

[photo of developing fruit] Fruit is a berry-like drupe, oval-elliptic, up to about ½ inch long, green drying to purplish, each containing a single, shiny black seed.


Leatherwood is a fitting common name, since the bark and twigs are tough but extremely flexible. Minnesota is at the western edge of its range. It is one of the most shade-tolerant shrubs and can thrive under a dense forest canopy, though it also performs well in a sunnier landscape. Queen bees pollinate the flowers in early spring and the fruit is mature by early summer. It is not easily confused with any other species. While the leaves may resemble any number of woody species, the jointed twigs that are so pliable they can be tied in a knot without breaking is a pretty diagnostic characteristic. But beware that it can also cause contact dermatitis.

This shrub is available at Outback Nursery in Hastings, MN. I bought one and planted in my yard. It really does well in deep shade.

Just realized I had one of these in my yard urban. Bought the house a few years ago but this is the first spring I noticed the blooms.

We found this blooming very happily in the ski trails at Sugar Hills! It was beautiful against the bare trees in the woods. Such a delicate looking plant to see.
