Saxifraga corymbosa, easy and reliable flowering rather
late in spring:

I like the citron yellow of corymbosa Rudi. Will those rosettes die and have to be raised from seed, or do they form clumps in time?

'Perseus' is a good one too, will keep an eye out for that one.

Tristan, Sax. corymbosa (syn.luteoviridis) is a very robust plant for places which get
not too hot in summer. It increases slowly by forming clumps, but it is more fun by
raising them from seeds if you are patient enough.

Saxifraga pubescens subsp. iratiana, a nice little mossy that seems to be settling in well.

Growing cushions plants which needs cool summer is if not a challenge, impossible in most lowlands parts of europe.
For the last 25 years i climb each season on the same mountains where i monitor Andrisace and Sax. I can affirm that 60% of these areas are now empty or with few subjets that burn a bit more summer after summer. For the 40% remaining plants moved 300 or 400m higher or those already at these altitudes are in good conditions. 25 years is a lot for a man but nothing for climate, just thinking about that is scary.
I've a good exemple on mont Visio, the last 3 years i tried to spot zones where Androsace helvetica used to be found, well nothing to watch except dry plants still fixed in the rocks. Last studies say s.oppositifolia climbed from 170m in the italo-franco alps range.

Except daily watering, shading and cooling plants it's a real challenge to grow these cutties.

Saxifraga hypnoides
. This is one of those saxes that spreads rapidly when it is happy, and goes backwards rapidly when it is not.



One of the encrusted species - callosa perhaps?

Sorry, I unfortunately  found this only today. Based on your observations it became more clear to me that here cultivatian of alpines in troughs in summer is only possible with daily careful care. This is how you have to endure carrying water cans. Another way is to restrict myself to more heat tolerant species.

Saxifraga aizoides. This grows quite well in a shady spot. I have two clones raised from seed, this one is flowering well this year.

I spent yesterday emptying out a couple of troughs whose contents had either reached beyond their time-span or weeds had conquered. Having done that the time is right to think about what I may re-plant in the troughs.

I've decided to go for a selection of Porophylla Saxifrages but here's the problem? The troughs are set up as mini-crevice troughs (nothing special, but I happened to have available quite a few broken paving slabs!) and I need to have quite small plants to use(ie seedlings). Saxes I've bought  over the years from a range of UK Nurseries would have been too large to plant in my quite narrow crevices. 

Really I could do with 20-25 plants, ideally all different.  So, be you a professional grower or a amateur, and you have plants to suit my needs do get in touch with me please, I'm happy to pay for plants, package and postage.

David, pm me if you want some pieces of any of the Saxes I grow. They usually produce plenty of spare pieces.

Thanks Ian, but I think it is some years since Mendle Nursery did any Saxes, they seem to specialise in Sempervivum these days.
