Sourwood

Native to the Southeast, Sourwood performs admirably in the Pacific Northwest climate. In its native environment, it is found growing at the edges of forests and roadsides. It is a close relative of the rhododendron and likes the same conditions – well-drained, moist, acidic soil enriched with organic matter. The common name “Sourwood” refers to the sour taste of the tree’s sap.

Clusters of tiny white flowers appear in summer and last a long time. They hang elegantly on the tree and give the tree a tiered look. They look similar to Lily of the Valley flowers and the tree is sometimes referred to as “lily of the valley tree”. The flowers are not only beautiful but beloved by bees.

As lovely as the flowers are, the tree’s most spectacular performance comes in late summer and fall when the leaves turn a vibrant red. They make a striking contrast to the flowers which still remain on the tree.

This is a very slow-growing tree and will take quite a number of years to reach significant height. In native habitats, it can reach 20 feet but in local gardens, expect a more compact 10-15 feet. A great tree for the patio or a focal point. This is a tree that will be sure to elicit comments for garden visitors.
