Oxydendrum arboreum is native to the temperate regions of eastern and southern USA. It is found in regions where the mean annual rainfall is distributed throughout the year and can range from as low as 1,020mm in the north of its range to 2,030mm in mountainous regions - winter precipitation can often fall as snow. Winter temperatures can fall as low as -20°c, with summer highs up to 40°c. The growing season can range from 150 - 300 days[1]. Requires a moist well-drained lime-free soil[2]. Prefers a pH in the range of 4 to 6[2]. Succeeds in light dappled shade or in full sun[2], it appreciates the protection of other tall shrubs and trees[3, 2]. Plants can succeed in deep shade in native woodland[1]. A very ornamental plant[3], it is rather slow growing, especially when growing at the limits of its hardiness[2]. Plants can flower in 4 - 5 years from seed. The flowers are sweetly scented[4]. Transplant with care, plants may take some time to re-establish themselves[2]. The trees usually respond vigorously to coppicing[1]. The flowers are very attractive to bees[5, 6].

Propagation

Surface sow the seed[7] in a shady place in a greenhouse either as soon as it is ripe in the autumn[2] or in late winter[8]. Germination is variable[8]. Put outside in a shady position as soon as it germinates and overwinter in a frame[8]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. The seedlings are susceptible to damping off and so should be kept well-ventilated and should not be over-watered. Cuttings of half-ripe wood, mid summer in a frame[2]. Very difficult to root, even with rooting hormones[1]. Layering.
