Lots of new seed-raised Irises are flowering for the first time this year, including some unnamed hybrids of the Sibiricae subfamily (above). These will require the usual conditions for the group - a damp soil in sun. They can be grown as marginals too but with the rhizome not too deeply submerged (an inch or so below the surface.)

Variable so best picked out from the nursery.

There seems to be a lot of confusion about Iris setosa and hookeri. They are related and have similarly shaped flowers and occur right across the sub-arctic from Newfoundland through Canada and Alaska across to eastern Siberia and northern Japan. As I understand it the shorter 'alpine' forms, mainly from Canada, have been known as hookeri, while the taller Asiatic forms are known as setosa, but in fact they may in fact just be distinct forms of one variable and widely distributed species.
I seem to have acquired examples of both forms.

Iris hookeri
