The Sourwood: A Firecracker of Fall

Few trees are quite as attractive in the autumn as the sourwood. The combination of the tree’s leaning growth habit, light gray bark, and flame orange to crimson leaves make it a truly spectacular member of the forest understory.

Accordingly – and because it often adapts well to residential areas – it is often planted as an ornamental or specimen tree.

The sourwood is also celebrated for the tasty honey that bees make after visiting its flowers. In fact, it is likely a very important food source for native and introduced bees alike.  

Sourwood Tree Identification: Tips & Tricks

The sourwood tree is usually pretty easy to identify. The leaves – which are more elongated than many other simple, alternately arranged leaves – are rarely difficult to distinguish from other species, and the tree’s often-leaning growth habit is usually sufficient on its own to provide a positive ID.

Further, the tree’s bark and flowers are fairly distinctive, and the species’ fall foliage will often allow for quick identification at a considerable distance.
