Eileen,
Do you know Hoyas are in the same family as stapeliads. All in the Asclepiads group like my Butterfly Weed I also grow. And to answer you question; Sansevieria (snake plant) are my first love. I currently have 45 or so different kind. Also Agave's, Aloes, Euphorbias, Haworthia and hybrids with aloe, and echevierias. and a few odd balls here and there.
