Phonetic Spelling:SAY-liks kair-oh-lin-ee-AY-nah

Genus:Salix

Species:caroliniana

Family:Salicaceae

Carolina Willow is a deciduous tree that can reach heights of up to 20 feet. Its leaves are arranged alternately, featuring a serrated edge, a hairy stem, and a pale white underside. The bark is smooth and gray, adorned with scattered warts and horizontal lenticels. In the spring, it produces an abundance of small yellow flowers, and by summer, it bears an egg-shaped capsule.

The Coastal Plain Willow thrives in nutrient-deficient soils and is particularly suited to wet environments such as thickets and swamps. It flourishes along stream banks and near ponds, often found in natural settings like riverbanks, sandbars, interdune ponds, and canal banks. While it can tolerate some salt spray due to its proximity to saltwater, it should be shielded from direct exposure by surrounding vegetation. This species is not drought-resistant and requires consistently moist soil conditions. Propagation can be achieved through seeds or cuttings, including root cuttings.

Although it shares some characteristics with the native Black Willow, the two can be distinguished by their leaves; S. caroliniana has broader leaves with a whitish underside.

Live stakes are frequently available for planting.

Salix caroliniana Feature Summary

Attributes
This tree provides some food and significant cover for wildlife. Its flowers attract bees. It is the only native larval host plant for viceroy (Limenitis archippus) butterflies. This is a larval host plant for several butterflies. Eastern Tiger Swallowtail (Papilio glaucus) has three flights in the deep south from February-November and two flights in the north from May-September. Mourning Cloak (Nymphalis antiopa) has one flight from June-July. Red-spotted Purple (Limenitis arthemis astyanax) has two broods from April-October. Viceroy (Limenitis archippus) has two to three broods from May-September. Eastern Comma (Polygonia comma) overwintered adults lay eggs in from early spring through April. The summer adults appear and lay eggs for the winter form from May-September which appear as adults in September that find a place to overwinter and start the cycle over. Eastern Comma rarely uses this host plant in North Carolina. It is also larval host for (Automeris io) moths.
