Below is a photo of an unregistered seedling iris attributed to Antoine
Hoog. I have seen it listed for sale as a regiocyclus hybrid (RC), but it
shows none of the oncocyclus features. It was discovered in his garden, as
far as I can discover. Anyway, it is a decent garden subject, fertile, and
grows well in a raised bed. From its form and coloring, it appears to me
that one of the I. hoogiana variants played a role in it.
