ID of two alpines

[michael z]

Hello,

I grow this two alpines a lot of years in my alpine garden. Unfortunately I do not know the names. Could you help me?

Hello Michael,

The first one is a houseleek (Sempervivum) - I'm afraid I don't know which one, there are quite a lot of species and thousands of cultivars! It reminds me a little of S. x barbulatum. Another possibility is Jovibarba allionii.

I'm afraid I can't help with the second, what do the flowers look like?

Best, Tristan

I thought Jovibarba allionii, too, for the first pic.

2nd photo looks like Gypsophila aretioides.

Thank you Gypsohpila seems to be right. In my opinion its not Sempervivum as the rosettes are quite small. Max 1cm in diameter. I should have taken the fotos with a scale. I expect some Draba species or something like that. What do you think?

[Rick R.]

I wondered what those whitish (sun-bleached?) dried little stemlike things were in the first pic.  Are they old flowering stems?  They certainly could not be from any Sempervivum or Jovibarba.

[Tristan_He]

Good point Rick! I think we really need photos of the flowers.

[Tristan_He]

Michael, could you send a closeup of the rosette of no. 1? Also of any dead flower stems?

Also, do the individual rosettes die after flowering?

Best, Tristan

Hi Tristan,

I will do. Thank you.

Mmm... thanks, I see what you mean about the size! I'm not sure to be honest, but I expect somebody else will know. Perhaps one of the Himalayan Androsace?

[Rick R.]

I am not sure what an Androsace seed pod looks like, but the remnant in the second pic could certainly be from a Draba.
