Actually, most of my orchids are growing in lava rock. I prefer that medium for my catts and dendros. Maybe lava rock would be better, especially with the heavy rains we get in the summer.
My friend actually just gave me a small cutting of Epidendrum radicans (I think, as it is just like Lorraine's picture) yesterday. She is from Jamaica originally and used to grow them there. She has this plant on her lanai and doesn't even really water it much this time of year and it is blooming beautifully! Most of the roots are out of the pot.
Anyway, this will be my experiment now to grow it in the garden. I'll keep you all posted.
