New Annual grass for next year - you know you want it

Pennisetum Fireworks. We planted it. We're waiting to see what it does. 2 feet, zone nine which means we need an insane amount of heat in a zone 5 to get this baby flowering. So far, slow as hell due to cooler weather conditions and rain. Like we're in august now people. What the heck is happening? We're having October weather here! Anyways, I think we're going to heckle our grower to do this one. VERY excited.
