I've seen Dietes listed as USDA Zone 8 or 9, so I doubt I could grow them here in Michigan except as a houseplant. That part of South Carolina is subtropical, with abundant native palmetto trees. It does get occasional snow and hard freezes.

I forgot about Iris planifolia - the only Juno native to Europe or Africa. Almost assuredly not hardy here.

Thank you Sean,
The Dietes are really lovely. How much frost and snow can they take?

Genus Dietes from south Africa. English common names range from unhelpful (African Iris) to downright useless (Wild Iris). North Africa is home to Iris foetidissima, I. unguicularis and several species of subgenus Xiphium (the also-ineptly-named Dutch irises).

I saw a nice clump earlier this month in South Carolina. They're common landscape plants and the occasional clump has a flower stalk up this time of year, but this is the only time I've seen an entire clump in full bloom in the middle of winter there. I collected a few seeds from an old pod, if anyone's really interested in Dietes and wants to see if the trait is genetic.

Hi Mark
It looks like you are growing I. unguicularis in pure sand – it that true?

      Here are three looks at a bloom on African Iris today. The flower is a bit battered because we had a big [but very welcome] storm early on.
