Osteospermums

I'm talking really of the standard ones (O. ecklonis). Osteospermums have been frosted down here, by a temperature of around -3C and a couple of -2's. Is it possible for Osteospermum to regrow from the roots, or is it simply when it's gone, it's gone?

 

I doubt , usually they die at -2 c , the roots are tender ....

 

Thanks Sal.. Ill probably just dig the twig out and chuck it then.

 

They usually are sold as annual because of that ....

 

It said on the label, hardy to -5C.. I guess that was untrue. But then again I should know better than to trust labels. There are hardy Osteospermums I know, but to be frank the hardy ones all look rubbishy and weedy from my perspective!

 

Here in Cornwall osteospermums are hardy. Tresco purple is common here ...purple flowers all summer and sporadically during winter. Cannington Roy is bit hardier and just as lovely all easy from cuttings and make good flowering plants in one season. I overwinter some tender varieties too...a yellow variety that is truly delightful and flowers til the frost.

 

.....I should add in west Cornwall. Colder in the east

 

I think these are also known as Cape Daisy. I have a large pot of these which I brought into the greenhouse for the winter in November.

A couple of weeks ago, I was sowing some seeds and as the planter is quite large and was in my way, so I moved the planter to just outside of the greenhouse and forgot about it till the next day, by which time half of the plants had died

We have it quite mild here in the south and I guess the temperature had only dropped to about -2.C but it was too late to save the plant............the good thing is that I only paid £1 per plant, there were 5 plants in the planter and half of them have survived, so not the end of the world and the seeds are cheap and easy to grow as well

 

Worth noting that the stems I cut are still green inside so by technical definition, they're still alive, but the leaves fried.. Not sure whether the leaves would grow back in that situation. Its also a similar story for the yellow ones. Osteospermum hardy types are completely hardy. But I've never tried tresco ones which might also be hardy here.

 

Prob worth covering with fleece during this cold spell

 

If the stems are still green I'd leave them and give them a chance to either re-shoot from the base or grow new leaves.

 

Well, I can't say much as they are everywhere here but they call them Dimorphotheca most of the time, purple ones and white ones ... no 'classy' names ... They are in full bloom at the moment and will continue to do so for months. Light frost doesn't kill the roots here.

 

Don't bin them yet. I lose some every winter, but some make it through. I've had some survive much lower than -5'C, though winter does wipe a lot of them out.
