Purchased at Seattle Flower and Garden Show in late 1990's and it has faithfully bloomed in November and March ever since. Finally dug the entire clump in May 2012 and tubers were crowded on top of one another 6" deep. Will not wait 12+ years to divide in the future ! Important to note: put it somewhere you will SEE it in November and March-this is a rugged plant to enjoy.

I have 2-year-old clumps of this Iris in both the Herb and Bulb Gardens at Kanapaha Botanical Gardens (Gainesville FL). They have been throwing blooms since mid-December despite our having had a record period of frost. It is truly a gift to have this beautiful Winter color.

This is such a tough plant and it is a bit surprising that such dainty flowers come from such a tough plant. My next door neighbours have two clumps and thay are totally neglected. No water, fetiliser or care. They also get full sun and don't flower but spread rapidly.There are others in our suburb that are huge and others that flower magnificantly. I just had to have one. I bought one at my local markets in flower for only $3 and it is very young. It is sending up 3 newbuds and is spreading already. I don't think it will flower again this winter but I hope it flowers next Winter. Such a tough, but lovely plant. pokerboy.

I received this plant unexpectedly in a trade. I was not impressed. It looked a lot like a clump of liriope! I stuck it in a dry sandy spot in the yard and forgot about it. Suddenly, in November, it surprised me with a beautiful blossom! I didn't want to pick it, since it was the only bud, but I couldn't resist, since I had heard that only one blossom would perfume an entire room. It wasn't an exaggeration! It has a lovely honey/lemon/vanilla scent. By the next day, another had flower had bloomed! This kept up through the winter and snow, until it dropped into the teens. This plant didn't suffer any frostbite, and stayed evergreen. I am on the border of 6/7 (I tend to push the zones a bit). This is an incredible plant that's full of surprises! I hope it multiplies quickly!

From what I understand, it thrives on neglect and doesn't need any special care or protection. It would probably be a great xeriscape or rock garden plant.
