Here are three ice plants I picked up this year. The nursery had no idea what varieties they are. The foliage reminds me somewhat of D. dyeri.
I'm hoping they are hardy here.

What about:

1) http://www.ppandl.net/index.cf...
2) http://www.ppandl.net/index.cf...

Hardy to USDA 7.

R.

Yup, those are they. There's nothing else like them out there.
Darn it, I'm definitely colder than zone 7.
I wonder if a good leaf mulch would protect them?

Delosperma Pink Ribbon sure looks like a match for the first photo.
Delosperma Perfect Orange looks like another match.
Would the last one be this? http://delosperma.webnode.cz/p...

Lots of fast draining soil and maybe a somewhat protected area. The will die back to the roots in your area, rot of the dormant roots is the big killer for the delosperma.

The last one is definitely not cooperi. I'm really familiar with cooperi since it's probably the most common iceplant around here. My purple ice plant has the same small, neat plant habit as the other two.

We'll see what happens. Some zone 7 things do well here despite getting down to -20 F, but those are things that die down to the ground for the winter.

The last one looks like Delosperma aberdenense, but I can't find any more photos of it to be sure.

It is listed as a species..

I found the same photo on Picasaweb..

I found Delosperma aberdenense x cooperi which has more D. cooperi flower form but leaves like aberdenense..

It seems to be all in Germany.

It's got a few mentions on European sites..

I know why I couldn't find more of that one! On the RHS it's Delosperma aberdeenense (I was begining to see the link to Aberdeen in Scotland.)

It's close .. the centres will open more like yours.

It's an AGM (Award of Garden Merit) plant which means it's a good one to have for flowering and form so will be widely sold.

This could be a Drosanthemum, the centres are not quite like any Delosperma I have found.. maybe a cross between the two!

Very interesting Janet. And it's in the same family as Delosperma. The fourth above link is a great photo and looks like a match. Everything I read on it says it's not frost hardy. : (

Drosanthemum floribundum 'Floribunda Purple'

Yes I thought that was very close too Lynn. The petals don't quite look the same though, they look a little longer and more narrow.

The first two plants as identified by Robert look to be fairly new in the market, if we could check out the growers or online suppliers of these for Drosanthemum we might find it.

Whatever they are, they've handled 15 F so far. I'm betting they won't do so well with -20 F though.

Since the nursery told me they all came from the same place, I suspect the third one is another in the same series and probably Delosperma Carmen Lucia.
Carmen Lucia does have that different center that Janet noticed on mine, which makes me think there was some interesting breeding going on in these plants.

I've definitely decided that I'm going to bring in some pieces and root them, provided they haven't gone too dormant. They would be plenty hardy for folks like Lynn.

It will be fun to watch things progress with them Tabby. It will be very exciting to find they end up being hardy in your zone.

Carmen Lucia:

These appear to be really really new plants. If they survive the winters in Wisconsin, they'll survive my winters. There's hope!

Ahh, a Dutch hybrid. How wonderful.

Lol, we posted at the same time tabby. You know the growers name? That's what I wanted to check out.

Delosperma Carmen Lucia certainly does look like it!

Lol again, I see you found the same link!

I have Delosperma ecklonis var. latifolia, I've had it for years and it keeps growing on a sandy bank but last winter knocked the life out of it, we had down to -17C but I still have some which have set in pots and there's some seedlings growing again on the bank. They got through the previous quite hard winter but last one was a stinker with 7 weeks below freezing.

I found the grower yesterday when looking up D. Perfect Orange, so I'll look and see if I can find it again.

There's more new hybrids on this 2011-12trade show.. yours must have been the 2010-11 new ones!

The write up:

New from McGregor is a range of 6 fantastic new Delosperma. Bred in Japan they are strong garden performers, extremely floriferous, flowering across a long period from May until October. These hardy, tri coloured, eye catching Alpines rooted from cuttings are available throughout the year in standard 84 cell tray (35mm paper pot). Ideal for 1lt pot sales. Delosperma hybrid Eye Candy, Perfect Orange, Pink Ribbon, White Pearl, Rise and Shine and Carmen Lucia.

They are all new!

Yup, that's the link.. The nursery also had the white and yellow one as well, so I'm sure that's what they are. This is great information!

I am truly amazed that they showed up at my little local nursery by accident. The nursery owner was not happy about it because they were all labeled Delosperma nubiginum.
The person who had labeled them at his supplier was let go, so there was no way to find out what had happened to cause the mix up.

If these survive the winter for me (and him since he keeps his perennials outdoors), then I can give him this information and he can label them properly.
