Culture
Grow in average, medium moisture, well-drained soil in full sun. Tolerates some shade. Also tolerates alkaline soils and some drought. Generally intolerant of the hot and humid summers of the deep South. Plants may suffer some tip damage or die to the ground in harsh winters, but should come back nicely. As with buddlejas, this plant may be grown in the manner of an herbaceous perennial in USDA Zones 5 and 6A by cutting back all stems close to the ground in late winter to early spring each year before new growth appears. Also may benefit from a similar hard pruning in warmer climates to maintain good form. Blooms on new growth.
