Id like to add three if I may. This I think is A. striatula, its quite hardy and does well in a sunny position in the UK with slight protection in cold weather. Not sure what this one is, but it flowered last spring, it doesn't appear to be hardy at all. This is my A. ferrox which I hope will flower one day.
No overwintering longk , they are hardy , this is mine after a -7c still frozen solid but alive . and on the back my aloe aristata the aloe aristata have lost the middle rosette , but they are regrowing again .....they are only hardy to -5c , but actually they are hardy .....
Ps Pete did you had any problem with the opuntia this year???? mine have lost the new leaf , but still alive , maybe to much cold and rain
I've never managed to get Aloe striatula through -4C, yet someone nearby managed to grow one to 12 feet high (staked).
Mine looks good too after -7°c. But this is the part of the photo that I was asking about................
If anyone is interested, Scampton Succulents has seed for Aloe polyphylla - not cheap though.................
I'm guessing you are referring to the Agave americana, its nestled in at the base of the house wall and the conservatory wall, facing West, so gets all available sun and no cold winds. Its also on the end of the area I cover, where the Strelitzia is growing.
Hi Sal, I tend to think Opuntia needs a lot of sun, so after a soggy summer the new pads probably didn't ripen, a bit like woody plants need to ripen the new wood before winter. Its just a theory.
That isn't cheap. If you look around at the cactus and succulent nurseries you can pick up a small plant for that
