Dennis, There are four species of Dietes, three of them from South Africa and the one outsider, which you now have, from Lord Howe Island in the Tasman sea. I've grown all but this one. They are so easy to germinate, that apart from saying water them, cover them lightly with any reasonable seed soil, and give them 50F or more, there's nothing to be done. They all self sow here with reckless abandon all over the garden. And, unlike most irids around here, the rodents leave them alone. After germination they grow steadily. If you're indoors I am almost scared to warn you about them. Yes, they will grow to 2 to three feet and spread laterally. The South African species tolerate drought very well but luxuriate if they get watered. From where it comes from, D. robinsoniana is probably more demanding of water. Andrew San Diego I just received some seeds of this species, and I'm wondering if anyone has any particular suggestions for germinating them. I've grown lots of irises from seeds, but almost no irids, and never Dietes. In fact, this is my first time ever to have a Dietes. I hear they get big! http://pacificbulbsociety.org/pbswiki/index.php/… http://en.wikipedia.org/wiki/Dietes_robinsoniana/ Thanks! Dennis in Cincinnati _______________________________________________
