They are very hardy. Unprotected ones survived -25 oF here in 2011. And, heat to 115 oF is fine for them, too. The local WalMart uses them in their parking lot. In my experience, RoundUp doesn't kill them, goats don't eat them. I like their looks.

Did not realize they were that hardy. Mine have survived undamaged and even started pupping. I am hoping to divide mine this year, since the one time they did bloom they didnt produce bulbils.

By here I mean Oklahoma, not Oregon.,

I like the way they look too, I just can't figure out why it keeps leaning over. I heard regular hesperaloe parviflora isn't as hardy. I have 2 that are protected from moisture and look fine. We'll see if 'brakelights' makes it through this winter from hell.

The regular hesperaloe par. is only hardy here if they are bigger plants and in well drained soil. I have not tried brake lights yet. 🙂

I have a pretty big sized regular hesperaloe par. that I got from Tampa Florida a couple of years ago. The lady at Home Depot in Tampa said "who would want one of those things?" She must not have seen them flower before. I might see if it will survive unprotected some winter.

That is funny how everyone thinks different, who would not one. I love the flowers and the plant form. 😀 Best of luck, I hope it does well for you. 😉

You have to remember some of this stuff is "exotic" for us in more temperate zones is like a weed in Flordia. For example my father was in the back yard last year and saw my Sabal Minor and said to me "You're trying to actively grow a Sabal and in Flordia everyone pulls them out because they're an intrusive weed." apparently Sabals and Washingtonia's seeds will sprout anywhere even in the crack of a sidewalk in Flordia. Most of us here wish we had that problem...

True, robustas are very much a weed in the south. But look great when older. 😀

And I just bought one. I can't wait for the 3.5' of snow to melt so I can plant it outside 🙂

I didn't know that H. parviflora is hardy in such wet conditions. Maybe it's time to get some 'breaklights' seeds 8)

Not sure yet. Updates will be forthcoming... Right now it's covered in snow but the snow will probably be gone in the next couple of days. Still, it looked great after much snow and -13 F (-25 C) so I'm hoping.

What happens sometimes with HP is that ... the center part rots out as the leaves are very cold hardy.....

The plant will send up new shoots but they may not bloom until the following year.

I was wandering if something like that might be happening. We'll see if the resulting plant is worth keeping or not or if protection might be a better option.
