Hi Rudi:
Your Saxes are very early.  Must be warm in Europe this year.
We have Saxifraga Winton in flower in the garden today (always early for us) and Amerigo Vespucci in the Alpine Shed.
Amerigo Vespucci (by Karel Lang) has interesting foliage and good flower colour.

Hello David, you are right, we had no real winter and the flowering season
started extremely early this year.
Saxifraga Lismore Mist
Saxifraga Allendale Accord

Well they would be if they were not upside down! Help Maggie please!
I thought  you were  illustrating  how  your show  plans  have  been turned upside  down by the  weather !
Fixed those  for  you, Sue. :)

I envy all of you who're able to grow sax in a greenhouse, even outside they burn with the warm summer despite been planted under shade. Silver ones are the only one i can keep.

The flowering season is really starting here on the west coast of Canada.  Cumulus is my favourite white.  I find it much easer to grow than Coolock Gem.

Such fine plants, thank you for showing. I like Peach Melba best, the change of flower coloring
is really amazing.

Nice to have some cheerful colours around these days

[attachimg=5]Thanks Maggi:
Flowering is really taking off here.  Saxifrage Sunday was planned for today for our Alpine Garden Club of British Columbia members but we had to cancel. The inspiration was the annual Waterperry Saxifraga Day. Maybe next year.  :(
Here's a few more pics.

David, I wonder please if you would give us a resume of your annual watering regime for your plants in plunges?
Title: Re: Saxifraga 2020
Post by: David Sellars on March 24, 2020, 12:48:58 AM
David:

Keeping Saxifrages moist is critical especially in the summer. We like to go away hiking in the mountains in July so I have set up an automatic watering system that keeps the sand wet. The clay pots absorb the water and the evaporation from the sand keeps the whole enterprise cool.

Originally I used a small diameter soaker hose but over time it was needing to be on 2-3 hours or more a day.  I replaced it a year or so ago with flexible irrigation pipe that has emitters every 10 cm or so. The new system only needs to be on 2-3 minutes a day!

The pipe is at the base of the sand.  The box is lined with plastic but has some drain holes in case the watering system goes haywire.  The first pic shows the pipe in the foot of the box.  The second is the inlet system.  In the third pic you can see the inlet at top right.

At this time of year I water by hand directly into the pot and the sand.  I use a very coarse potting mix so can't overwater.

I forgot to mention that when it gets really hot on the summer (and I am around!) I spray the whole plunge bed by hand to help cool things down and add extra moisture to the pots.

I discovered this strange color combination on one of the saxifrageas yesterday...  all the flowers are salmon pink...  ...and a yellow one in the center...  odd...  ...but beautiful.

Looks like a good place for this beauty, it can grow for a long time in that hole.
The big flowers on these tiny rosettes are simply amazing.

Saxifraga pubescens, always very free floering.

Mukdenia rossii 'Karasuba' .  Moved from a spot in the garden where it never flowered, it seems to like it now.

Very nice S. pubescens.  :D I have had difficulty keeping it going here.  What are you using for potting mix? Any special treatment you are using?

Thanks

David
Title: Re: Saxifraga 2020
Post by: ruweiss on April 18, 2020, 08:35:15 PM
David,
Sax.pubescens grows at high elevations on granite in the Pyrenees, so my plants are cultivated
in a lime-free mineralic soil with just a little amount of humus. During autumn and winter they
get protected from overhead moisture, the plant at the photo is in the alpine house.
Good luck with these fine plants!

Saxifraga "Cassini"  (aretioides x dinnikii)
Title: Re: Saxifraga 2020
Post by: Tristan_He on April 21, 2020, 09:33:18 PM
Saxifraga andersonii. For a Himalayan species this is pretty easy, it gets a bit bigger every year and is now something of an old friend. It flowers a bit later than most of the other saxes and can be a bit shy flowering some years. Then out it pops... or not!  ???

Here is the main patch - half of it has decided not to flower.

[attachimg=3]

A secondary patch is a bit more floriferous.

Close up. The flowers open pink, then fade to white.

Found a very good red form of Saxifraga media in 2015 above the Port de la Bonaigua east of the Val d'Aran in the Pyrenees.

[attachimg=1]

Collected some of the previous year's seed heads and grew them on. Planted out three on tufa and this is the second to flower.

Lovely  to see David. I wonder  how  long  it  will be  before  the  mountains  will be  visited again? A  long time , I reckon.

Thanks Maggie.  We are hoping to get into our local mountains in June as soon as the snow melts.  Our Provincial health officer says "Please, go outside" for our mental health given that coronavirus is much less likely to spread outdoors.

Saxifraga 'Southside Seedling'............. It might be common but very pretty for all of that.

Two Saxifraga fortunei cultivars that have done well this year. 'Eiga' must be one of the most floriferous fortunei types available, it reliably covers itself like this every year.
