Oncocyclus Iris 2014

You seem to be growing the lowland species which are the ones that do well for me too. I. mariae I have lost over the years

I've been slowly rebuilding my Onco collection for the last couple of years and I'm pleased with the ones which have flowered for me this year:

I. damascena. First flowering from a division obtained only two years ago and it produced 5 flowers    However - it did go dormant quite early and the leaves took on an almost virussed look as they died back. I have separated it and will keep an eye on it next season.

I. nigricans.

I.sari - a small form

I. (iberica) elegantissima

the last flower this spring:
Iris paradoxa f.atrata 'Gem of Lori'

Hi Udo
Interesting. do you have problems with the iris roots growing out the bottoms?
do you have the pots on a sand base or on greenhouse table or on a wire grid table?

i tried a few oncos in 4" (10cm) pots by 5" (13cm) deep and they did ok and i got a bloom or two but they did much better in later years when i removed the pots and just planted them in the sand plunge.

What do you do for summer dormancy?  i have mine outside in a sand bed in afternoon sun. but we got lots of thunderstorms sometime without any warning and i cannot always cover them. I don't have a greenhouse.

do you grow Iris camillae? any special culture?

Hi Wimmer,
the pots stand on dunes situation gravel directly on the surface of the earth. The patch is covered the whole year with a window. I do not have problem with root decay, importantly is absolutely enough air movement. From the middle of June till the end of September they completely dry.
Iris camillae I do not have yet in culture.

Hi Rimmer,

I also prefer to grow them directly in the sand, to in the ground under cover.
Iris camillae is a good grower, and, as usual, keep it dry from may to october.

Some arils starting to bloom here. Mainly dark species hybrids. The rain and cold might be not that good for them though. Seems that it has been cold and wet for the last month. I was in London and Winchester for three weeks but came home a week ago.

Welcome to the south hemisphere blooming time  and pictures 
Everything (almost) is dry and yellow here !

The year is passing quickly.   Already, the first onco species this year for me, Iris haynei from seed from David Shahak, 1986 and embryo cultured in 2012.

[arillady]

Beautiful Peter. The arils here have had to put up with frosts the last few mornings so aren't looking the best. Oh for some prolonged sunshine. At least we aren't in Canberra which is really cold the last week or more.

seems that south meets north 
Here is Iris paradoxa ssp. coshab blooming.... today in the greenhouse !!!
Season is crazy !
