Meadow Willow

Family: 
Salicaceae (willows)
Description: 

A low-growing, clumped shrub with slender, upraised stems.

Leaves simple, alternate, 1¼–3 inches long, ½–¾ inch wide, lance-shaped, tip pointed. Edges finely toothed with gland-tipped teeth, but teeth do not occur at the base of leaf.

Bark is gray-green or red-brown, becoming dark brown and either smooth or flaky.

Twigs red-brown or yellow-brown, nearly smooth or with whitish hairs; pores small, barely noticeable, yellow-orange.

Flowers April–June, male and female flowers in separate catkins in axils of leaves.

Fruits June–July, erect catkins, ¾–1 inch long, with conical capsules having silky hairs; seeds cylindrical with long, silky hairs at base.

Size: 
Height: to 10 feet; spread: 10 feet.
Habitat and conservation: 
Occurs in low, wet ground in mud or sandy gravel along streams and in wet meadows. In nature, it is associated with other willow species and cottonwood. If you are thinking of planting this tree, keep in mind that ideal sites have wet soil and full sun.
Distribution in Missouri: 
Occurs naturally only in the northeastern part of Missouri, along the Mississippi River from the Iowa state line to St. Louis.
Status: 
A Species of Conservation Concern, this shrub is critically imperiled in Missouri. The reason it is so rare here is that we are at the southern end of its native range. It is found across southern Canada, through the Great Lakes states and into New England; this willow is only found naturally in the northeastern part of Missouri.
Human connections: 
Humble streamside shrubs like willows serve to stabilize stream banks, which helps protect neighboring lands (including agricultural lands) from flooding. Likewise, it prevents our valuable farmland from washing away into the stream after heavy rains.
Ecosystem connections: 
The twigs and leaves are browsed by deer. The shoots and buds are eaten by many rodents, including muskrat and beaver, as well as by rabbits. Some ducks and water birds eat the catkins and leaves. Bees make a high-grade honey from the nectar. The dense thickets provide valuable wildlife cover.
