Identify these please.

When I started to collect again my kind grandson bought me these at a garden centre- no names on them.
Anyone got any idea what they are.

[juster]

I think that no 1 is Echeveria agavoides, no 2 is probably a Graptopetalum, maybe a hybrid, not sure about no 3. Nice plants, kind grandson!

1 agreed, Echeveria agavoides
2 = Graptoveria 'Silver Star'
3 = Senecio talinoides (reasonably sure).

[Ernie]

Thank you.

What is the difference between this and Senecio serpens?

[ralphrmartin]

That's why I said "reasonably sure".

I'm not sure if there is any difference, although S. serpens seems to have slightly shorter and fatter leaves than S. talinoides, at least in the plants I have seen.

Perhaps John Foster can chip in...

The 3rd plant is either Senecio (talinoides ssp.) talinoides or Senecio (talinoides ssp.) cylindricus.

S. talinoides will get quite tall (2' or more) whereas S. serpens is more squat and spreads ("serpens" means creeping). Serpens has shorter flatter leaves and tends to be a bit bluer.

To keep up to date, both these plants are now in the genus Curio. In the case of S. serpens it's now Curio repens.

Looks less like cylindricus to me. I have a large sprawl of both serpens (got it as 'mandraliscae', I assume that's basically the same?) and cylindricus, and a smaller v talinoides (all growing outside). The difference is clear when viewed side by side (maybe less so in a photo). Serpens (and v talinoides) is much more blue, with thicker leaves and a chubbier appearance compared to cylindricus.

Serpens is a great ground cover, very nice color. Only drawback is that it is very vigorous here, and it will swamp any plants growing near it if left unchecked. I threw out 50 lbs of cuttings when I trimmed it last month, and I planted them just last year. Cylindricus is a little more restrained, but taller stems also like to sprawl.

Thanks, John!
