Missouri River Willow


(Salix eriocephala)

The Missouri river willow is a shrub 7 to 13 feet tall, native to dunes, shores and lowlands of Eastern to Central North America. The young, unfolding leaves are copper coloured to red. Mature leaves are lance-shaped with a round to heart-shaped base. Leaf colour is green above and whiteish below with finely toothed margins. The flower catkins appear in April at the same time or slightly before the leaves and are pollinated by many insects especially bees and flies. Missouri river willow tolerates strong winds but not seaside, and is shade intolerant.

taxonomy for this willow has been uncertain and everchanging. It is closely related to and often confused with Salix rigida (Heart-Leaved Willow), and Salix glaucophylloides (Blue-Leaf Willow). Willows sometimes hybridize, making identification even more confusing.
