They are tall perennial herbs with large compound leaves and small white flowers in slender spikes forming large terminal panicles. The species in cultivation is hardy North; it prefers rich rather moist soil and grows well in half-shady situations. Propagation is by seeds, which germinate readily, and also by division of older plants.
