x Semponium

When I visited Tremenheere Sculpture Gardens, Penzance recently, I popped into Surreal Succulents to check out some intergeneric hybrids they claim to have produced, x Semponium. These are supposed to be hybrids of Sempervivum and Aeonium.
The only differences I could see were a) the x Semponium leaves were more rounded and b) the prices.

Aeonium 'Velour'

Aeonium 'Voodoo'

x Semponium 'Destiny'


I'm not a botanist or anything, but I can't say I am convinced.
What thinks you guys?

 

I think they are hoping hardiness when crossing these.

 

I see you've already posted on another forum in their recent thread on these.
That thread is worth a read as are the links.
Overall I'm not convinced by them and would rather spend my money on some interesting Sempervivum cultivars.

I don't know if it will work, but this is a link to the thread.

Some time ago I had 3 different Semponiums in pots. I kept them in the cold frame in winter (no greenhouse). As far as I remember they all got eaten by snails - I wouldn't recommend them.
Also they never grew very much in the time I had them.
