Pennisetum setaceum 'Rubrum'

(Zone 4a)

If anyone has successfully overwintered this grass in a cold zone,
please share the secret with me.

My plant does not look the greatest, and I have restricted water.
It sets in about a 60 degree area.

Many thanks,

It's herbaceous so it does die back in the winter--I usually cut mine down in late fall/early winter and then it starts to sprout back in the spring. If you didn't cut it back before winter, that's probably why it's looking a bit ratty now. I can grow it outdoors here and it'll see temps as low as 28-30 in a typical winter and it comes back from that just fine so as long as you don't let it get colder than that it should be fine.

Thanks, ecrane 3.

That is encouraging news.

In zone 6, mine dies and I need to replace it every year. The seeds will not germinate. I have tried for two years to overwinter in the garage with out success. If anyone else has, I will be watching the thread for the trick. Sorry for my bad news...

(Zone 4a)

I read that the seeds must mature before they are viable, which means it
needs a long growing season. Hmm...

I cut mine back, albeit late, and have moved it to a sunny area.
Trickly little fellow, but I will keep trying.

Thanks for the help.

I don't know how long it takes seeds to mature, but I know that there are some species of Pennisetum that are very invasive, so many of the cultivars that you can buy have been bred to be sterile, so if you have one of those then it wouldn't matter how long a growing season you have, you still won't get germination.
