I have this for at least 6 years. Ever green, even in our terrible winters 2010/11 it hardly froze back then. Always blooms this time of year clear up to our first frost and is VERY well behaved, stays in it's own little spot. Produces seeds but I only see a few come up here and there, but that very well could be because it's where they would be mowed on a regular basis. Drought tolerant and never get's any fertilizer. About 12 in. high and 18 in. around.
