I just noticed this thread. Not sure if anyone is still listening, but just in case...
Silverhill offered this species once or twice in the past couple of decades. I have been growing it since 2013, and I know of one other person who has it as well. It hasn't bloomed yet for either of us. In my garden, the corms produce one long threadlike leaf, each year a little bit thicker and longer. Hopefully some day they'll reach blooming size.
I'm able to bloom most of the other winter-growing Moraeas, so I am not sure what the problem is for this one. Maybe I need to burn something over it in the summer, or maybe my climate is a bit too dry for it. It native habitat is a bit moister in summer than mine.
I presume other people have had similar problems getting it to bloom, or it would be in circulation by now.
If anyone has suggestions on how to make it happy, I'm all ears.
Mike
PS: If I ever get seeds from it, I'll share them.
