The plant seems to be inside of a glass, so it is hard to see, maybe if you take it out of the glass container and take more pictures.
yes, definitely succulents. are they the same thing? kind of look like it - that could be the glass interfering though - the smaller one is less clear due to reflections. the one on the left looks like it might be an aeonium. i'm not quite sure though. they're both very nice plants, though, regardless of what they are!
Actually I found those plants on Crate & Barrels website, but more than the vases, I liked the plants. Can I plant these the way they are shown...in sand?
