I would like to find some of this. I have anomatheca laxa, which I grew from seed and it finally bloomed this year. I understand there is at least one other variety.
Carlett, I suspect you already know the synonyms for Anomatheca. I looked some up and you can sometimes find it other different names. For instance, Silverhill Seeds sells it as Freesia laxa.
Here are the synonums I found.
