Cute succulents arrived.

I took some time off myself this weekend, and I met these guys at a flower shop. I have been wanting succulents to satisfy my nostalgia for California nature. There were many to choose, but I particularly fell in love with this square shaped one. Never seen this kind before. It looks so unreal for plants:-) Do they grow taller? I should find out about it. It'll be fun to have many of them.
