Nice plants Alain. Sometimes I don't think Faucarias get their due. They are attractive in and out of flower, and they are one of the easiest mesembs to grow. I have several old plants of F. tuberculosa and F. boscheana. There are some very nice color forms of F. tigrina. The teeth on your plants are very showy. I'm surprised they aren't more popular. Maybe they are too easy.
I agree they are underrated. Look good and flower well. I have seen some nice purple forms but have not been able to get one.
