Leontochir ovallei is from northern Chile, where it grows in coastal regions that receive almost no rain. It obtains most of its moisture from condensation from fog, and it is considered endangered. I received some seeds four or five years ago, and finally saw a beautiful bud emerging. As I was reaching for something else on the same bench, I broke off the stem!! I almost cried, but put the stem in a tub of damp pumice, and it finally opened its buds. It probably doesn't look quite as good as if it had matured naturally, but I will take what I can get.
In spite of Leontochir ovallei's natural environment, virtually no rainfall, and growing in very dry rocky conditions, I haven't found it that difficult to grow. I grow it in pure pumice with no organic material added, and I fertilize occasionally while in growth and water about once a month, but my plants are on a bench that get sprinkled with rain coming through the greenhouse vents. The thick fleshy stems emerge in winter and grow from a crown, with rounded tuber like storage organs attached to the roots. My non-blooming plants are starting to die back.
