Willows: Keystone Plants for Pollinators, Birds, and Clean Water
When the first warm days of spring arrive and native bees begin emerging from their winter shelters, willows catkins provide one of the earliest pollen and nectar sources at a time when few other food sources are available. But that's not all.
Willows (Salix spp.) are considered a keystone genus, meaning they support a disproportionately large number of insects compared to most other plants. In central Ohio alone, willows host >300 species of caterpillars.
And caterpillars matter. They provide more insect biomass to the food web than any other type of insect. Most of our terrestrial bird species rely on them to raise their young since they’re the easiest to gather. (Did you know baby birds in the nest are unable to digest nuts and seeds from our feeders?)
Over the years, we've found several caterpillars species feeding on willows here at the nursery, including Red Admiral and Viceroy butterflies, and the striking White Furcula moth. Countless other moths, butterflies, bees, beetles, and pollinators also depend on willows for food and habitat.
Willows also protect our waterways. Their extensive root systems stabilize streambanks, reduce erosion, slow runoff, improve water infiltration, and help filter pollutants before they reach streams and wetlands. Whether planted along a creek, pond, rain garden, drainage swale, or low area of the yard, willows are among nature's hardest-working watershed plants.
We've got a willow for nearly every situation. All willow species can be cut to the ground each year to manage height.
P***y Willow (Salix discolor)
Famous for its soft silver catkins. Grows 6–20' tall in full to part sun and average to wet soils.
Peachleaf Willow (Salix amygdaloides)
A fast-grower reaching 30–60' tall. Excellent for larger properties, ponds, and floodplains. Prefers full sun and moist to wet soils.
Shining Willow (Salix lucida)
A beautiful large shrub or small tree with glossy foliage and stems. Great for weaving. Typically grows 12-20' tall in full to part sun and moist to wet soils. Tolerates heavy clay and poor soils.
Sandbar Willow (Salix interior)
A multi-stemmed, suckering shrub that reaches 15-30' tall in moist to wet soils and full to part sun. This willow has the longest, narrowest leaves of any of the willow species.
Dune Willow (Salix cordata)
A smaller willow, typically 3–8' tall. Great for rain gardens, and adapts to sandy and well-drained soils where many other willows struggle. Best in full sun.
Prairie Willow (Salix humilis)
Our most compact willow, usually 2–6' tall (can reach 10’ in ideal conditions). A great choice for part to full sun in average to dry soils and smaller landscapes. Beautiful blue-green foliage.
