I did a little more research by googling "Nivenia", and found out that Martin Grantham wrote a nice article about the various Nivenia species he has been trialing,(that can be found on the web), and that San Marcos Growers no longer sells/grows Nivenia corymbosa at their nursery. I also discovered that the Australian genus Pattersonia is related to Nivenia, and I can highly recommend P. drummondii as an interesting irid with delightful lavender flowers as something to seek out if you've never grown it. Suncrest Nursery has been growing several Pattersonia species for years, and they are very easy to grow, except that they seem to resent dividing as much as Dierama pulcherrimum does. That SMG has stopped production of N. corymbosa would seem to support my conclusions that it is not the easiest plant to grow under California conditions, or maybe
it was just too slow as a nursery crop to be a viable plant for San Marcos Growers. Also, it does prefer moister soil conditions in summer, which doesn't exactly make it a good candidate for a dry garden.

As far as I know, Martin Grantham, who was the grower of the Nivenias exhibited, is probably the best and only source for the majority of the species shown, they aren't in the trade yet, except for Nivenia corymbosa,
which is listed in San Marcos Growers current catalog. Martin lives here in nearby Emeryville, and currently works at San Francisco City College. He has been searching out and growing various rarer South African plants, including Nivenia species and Restios, amongst others, and also has/had quite a collection of Magnolia species and their vining relatives as well as various rarer tree ferns. I'd suggest you contact him if you just have to have some.
It might be worth mentioning that southern California poor water quality may be a major issue in getting them to grow for you, and they are mostly very slow growing and perhaps
a bit gawky looking when not blooming.

At the San Francisco Flower Show last month, I was totally captivated by the Nivenias. These are blue-flowering iris relatives that are out of this world! I'm wondering if anyone knows of a wholesale source for them (or retail for that matter) in California.
Hope you can help!
