The National Audubon Society presents a new line of native plants and trees that helps birds and wildlife thrive in your area! The fragrant Audubon® Native Sourwood Tree (Oxydendrum arboreum) has been nick-named the Lily-of-the-Valley tree! The bark actually tastes sour, inspiring the name "Sourwood".

Featuring airy sprays of white flowers in summer, lava-red foliage in fall, and handsome, blocky bark, this elegant native has something to offer every season! The sweet blooms grow on the drooping stems, giving them a lyrically old-fashioned charm.

Fragrant white flowers arrive in early summer on long panicles. Honeybees adore the tiny, urn-shaped blossoms held on long stalks in large sprays at the branch tips. It’s a pollinator paradise and beekeepers know it. Honeybees make what’s considered to be the finest honey in the world.

Planting and Application:

Sourwood Trees are ideally sized for modern lots and a superb choice for a shade or accent tree in yards with dry, acidic soils. It has a romantic weeping appearance, with slightly downturned branches. Even the leaves and the sweet flower clusters dip towards the ground. Try it as an irrigated lawn tree for a high-impact look.

Impressive Fall Color Trees, the large leaves really shine when dressed in their autumn finery, sure to turn every head in the neighborhood. These are beneficial for wildlife, feeding and sheltering Cardinals, Grosbeaks, Wrens, Sparrows, Thrushes, Orioles, Finches, Mockingbirds, Thrashers and Vireos!
