Additional Information

This plant gets it common and scientific name from its sour-tasting leaves. The genus name is derived from the Greek word "oxys", meaning sour, and "dendron", meaning tree. Honey produced from the pollen of Sourwood flowers is considered valuable. The attractive, slightly fragrant flowers are often prolifically produced, especially in full sun, and are effective for up to four weeks. Like all Ericaceous plants, Oxydendrum arboreum requires rich, organic, moist, well-drained, and acidic soil. This plant is best grown in full sun, but can tolerate some shade, at the expense of flowers and fall color. This plant is not appropriate for polluted, urban, or drought conditions.
