I kept mine fairly moist at all times, and it gave me gorgeous blooms. I got 5 off the plant this year, each being about 6 inches or so across. Im hoping next year is even better. The get full sun in the afternoon, otherwise its bright ambient light until sunset.

Compact, usually not exceeding 5'. Thick, sturdy branches. Flowerheads have 5 or 6 sepals making flowers look double, serrate; flower heads stay in good condition turning green, red or purple tinted in fall. Colors range from pink to carmine red in alkaline; purplish/rose in acid soil. Hardiness is suspect. No zone given.
