Second plant is actually a Sedum clavatum. It's a great little plant, very attractive blue color and easy to grow!

I'm going with 'anything' myself, but that's an excellent suggestion you have, cardio.

Isn't it amazing how different plants can look when grown under different conditions? I've beheaded and rooted and grown from leaves. Since I am terrible at marking what my babies are, I often get them mixed up. Here, I was in the process of beheading and replanting an area of Vera Higgins. Oops - looks like I couldn't tell the (now red) California Sunset from Vera Higgins when I planted them. So I quit trying to segregate the different colors - and wondered why I hadn't done that before. You can see lots of red California Sunset in the middle of this picture. And believe it or not, plant #1 is also CS that I propagated under different conditions. It will eventually match in color. Plants #2 are Vera Higgins. And if all these subtle differences give you a headache when trying to ID, the flowers will help confirm things. Vera Higgins has yellow flowers. And California Sunset has white flowers. So now that I've given you more than you asked for, I am happy to say that the preferred conditions is the same for both plants. Good luck and enjoy!

i see no reason why any houseplant cant go outside for summer... but in full shade ... but then.. as noted ... if there is no drain hole .... then you have to be careful about rain ... ken
