Maybe it need a little more fertiliser
Here they multiply well

Thanks for that Roland
Never thought of that !.

I don't think i've ever fed it ...Duh !!

I'll 'nuke'   ;) it with bone meal and see what happens .

Cheers Dave.

Maybe also with an ordinary fertiliser like 12-10-18 + micro or spore elements
Bonemeal is fantastic
but a very slow fertiliser
also maybe a little chalk , Dolomite or whatever you call it where you live
if your garden is a little acid

Dave,
"George" does well for us but I'm pretty sure we're a lot drier than you are!
We don't feed them and they still multiply but that could be because the soil is a rather rich but heavy "adobe" clay [to which we've added a lot of grit/gravel/sand]. The other thing we do is plant them in raised beds or mounds so that drainage is as good as possible.

What type of soil do you have
I have to try this one in my garden
they don't like much my potting mixture
but probably my soil is to wet in the summer

Hi Roland,
We are on heavy adobe type black clay! But this iris is planted in a raised bed which has had the soil "amended" by the addition of compost and a lot of coarse sand/grit. In parts of this bed it is almost 50% sand.
We usually have dry summers but the last 2 years they have been quite wet with over 2 inches of summer rain! I think the extreme drainage is the only thing which saved this iris! One small [partly-rotted] bulb was rescued from its pot [which hadn't been kept dry] and was re-planted in almost pure sand - I don't think it put up any growth last year but I just noticed some foliage emerging just this week, so I'm very happy that I didn't lose it altogether.

At present we have more retic iris in flower:
- the first we just bought on the weekend in bud - 'Purple Gem'

'Harmony' is the most popular or at least the most commonly grown retic iris here

This is the main clump of Iris 'George' - originally from a single bulb planted in 2002!

cheers

Fermi --i'm not sure if my 'unnamed 'Iris below is I.ret.purple gem ---whatever it is it's such a good 'doer' here  --quick to multiply and plenty of blooms.

Pic taken last Sat ,there were 5 flowers open as at today.

Cheers Dave.

So pleased to see this in bloom today --Iris winogradowii --I used to have a good sized patch in the garden but for some reason they were going backwards --potted up a few ,the last   :-\ ,(I'm getting old ),  :) or maybe the year before so i haven't lost it altogether.

There is another bulb with a bud yet to open.

I was out with the paint brush just before to try and 'self it' but i wasn't sure if i had managed to transfer any pollen from the anthers to the stigmatic lip ,(i wiped both sides of the anthers ).Does anyone know if i should be able to see Iris pollen with the naked eye ? .Thanks.

Cheers Dave.

That is such a beauty, Dave!  One that is really piquing my interest in the last couple years. 

I too have noticed the seemingly sparse pollen on several of the small iris species.  I have begun to wonder the same thing: if the pollen grains I do see are really clumps of grains, rather than single grains, and the single grains are just extremely tiny. ???  When I have tried to do what limited hand pollinating I've done with them, success is no better than natural pollination!  :-\

On the other hand, maybe I am just clumsy. :D
