Graceful large ornamental grass, rich burgundy purple colour, with purple-cream fluffy foxtail plumes year-round. DESCRIPTION: Large size grass with burgundy-maroon colour and a weeping form. Soft feathery plumes all year round.
The best time to trim the purple grass is in the early spring or late winter. Although exact timing is not very important, make sure you prune the pennisetum grass before it starts growing actively. Avoid pruning during the fall as the grass has not yet dried back all the way.
It's cold-weather hardy down to about 20 degrees Fahrenheit, so if your area remains about that temperature, then you can grow the grass as a perennial and cut it back in early spring each year.
Purple fountain grass has been listed as a non-toxic plant by Pawprints and Purrs Inc. This means eating purple fountain grass most likely won't result in death, but it still can cause symptoms such as vomiting, diarrhea, depression or a combination of these symptoms.
