I was surprised today to see that a new generic name was given to some Pennisetum species, including this one, to Cenchrus. This is the most common cultivar of the Oriental Fountaingrass. A good number of conventional nurseries sell some, but it is only occasionally planted. This differs from the mother species that is native to western Asia in having a bright green foliage rather than gray-green, in having darker, more rosy, larger and fuller flower spikes, and being more cold hardy to Zone 5a. I grew one at the side of my garage for about 7 years. I obtained it from digging up a seedling that was produced in the landscape of one of my customers. Floridata reported that this species is not invasive but it does self sow some around the mother plant. As time goes on, the clump starts to sprawl around itself by short rhizomes, and the middle of the clump eventually dies out after 5 to 15 years. Therefore, one should dig the plant up and reset it when the center is dying out or when the plant gets too large and thick with sprawling. Another note is that it is recommended to not cut this grass too low to the ground in late winter or early spring because it won't sprout up as well. It is also a warm season grass, so it does not show life until mid-Spring in late April to mid- May This is definitely a nice, beautiful, soft clump grass species. However, I got tired of my specimen spreading beyond its bounds along the garage strip and I wanted to get more into the native plant theme, so I took mine out and replaced it with Little Bluestem that is upright growing.
