An exciting Broken Arrow Nursery introduction that we discovered in a client' s garden. 'Harvest Moon' has attractive, burgundy-flushed new growth that matures to dark green. In late fall, plants offer numerous clusters of large, lemon-yellow flowers that are closely spaced along the branches. The overall effect is a much showier display than is common for the species. In our trials, plants have flowered up to two weeks later than the species and remain showy after the foliage drops. In cultivation, plants are vigorous growers and assume an upright, vase-shaped habit maturing 15-18' tall in 15 years.
