Here are photos of some delightful Chinese Iris species. Iris koreana photos and one of I. odaesanensis are taken in Darrell Probst's Garden Vision Nursery (actually now run by Karen Perkins, his ex), the remainder taken in my garden. In partcular, there's much excitement with I. henryi. It has very narrow almost grassy foliage, and exquisite palest blue flowers. Darrells collections include some different shades of blue. I include a photo showing lots of seed pods, alas all pods were empty. The I. minutoaurea takes a while to get established (shy to start flowering), but then it goes to town. Tiniest of tiny flowers, simply delightful, although in this species the foliage elongates after flowering to ridiculous lengths, similar to reticulatas.
All are rock hardy here, and in particular, I see I. odaesanensis competing with I. cristata as an easy groundcover sort of Iris. Darrell has tried hybridizing these Chinese Iris with the many forms of I. cristata... no luck so far, not a single seed. I'm getting self-sown seedlings of odaesanesis and the yellow koreana, so I'm hoping that maybe the bees have better luck at mixing things up.
I also include a photo of I. gracilipes 'Buko Form'... a dwarf white-flowered form, it too is starting to seed around.
