It is one of the Juno irises. most are very difficult to grow and require great care in a bulb house. Therefore I am going to suggest the easiest of this group, Iris bucharica and it will have yellow flowers.

That does ring a bell and I love yellow. But it isnt in my little book. These have been outside all winter. Is it a very hardy one then BA.
Thanks for the help. :o)

I bucharica is the only juno guaranteed to do OK out of doors in the UK.
Having said that I cannot grow it outside! Few growers believe me when I say this but my outdoor ones look like very undernurished leeks and don't flower.
Those in pots in the cold greenhouse are another matter and I have two large potfulls growing away nicely to flower just after Easter.
Yours are looking nice and healthy and I expect them to be fine.

thanks for the info.

Sbg - I have it outside but I haven't seen it yet this year :-(

dont give up hope these came through -12 and lots of snow etc. I cant wait to see them flower I hope they will in their first year with me. I assume they are a bulbous type. But I have no recollection of them at all.

This reminds me of my mother. "Steve, whats this perennial coming through, I've forgotten". Lol

and i am not that senior yet. they say with every child you lose a little of your brain. I only have 2 kiddies help!!! :o)
