Plants grow 15 to 24 inches tall and produce spikes of rose pink colored flowers. Blooms heavy in mid to late spring and on-and-off during summer and fall. Full sun in the north to light shade in the southern part of the country. They like well drained - even dry soils but do best with cool nights and some soil moisture. Under hot and dry conditions or in to much shade they tend to flop open. Cut back after the first flush of flowering is done to produce a second flush of more compact growing flower stems.
