I recently bought a mixture of many different spring bulbs. I know the other bulbs will do just fine here in Norman, Oklahoma. However, in the mix were 40 Iris Hollandias. No specific cultivar was specified. They look lovely and I would love to include them in my garden, but unfortunately, from what I've read online, I really don't think they will make it here.

Has anyone grown these successfully in my zone? Does anyone have any tips or hints on how to successfully grow them? I wouldn't mind potting them, if that is the only way.

Thank you.
