Karley Rose Fountain Grass questions

Is Karley Rose Fountain Grass invasive?

It is generally considered a better behaved choice than species like Pennisetum setaceum because it is largely sterile and produces little to no viable seed, but gardeners should still check local invasive plant listings before planting.

Will Karley Rose Fountain Grass come back every year?

Yes, in USDA zones 6-9 it returns as a perennial each spring from its root crown; in colder zones it is usually grown as an annual or requires heavy winter mulch.

When should I cut back Karley Rose Fountain Grass?

Cut the clump back to a few inches above the ground in late winter or very early spring, before new growth emerges, rather than in fall.

Does Karley Rose Fountain Grass need full sun?

Yes, it performs and blooms best in full sun; too much shade causes weak, floppy growth and fewer plumes.
