Cypripedium japonicum

Wim,
Nice flower on not an easy to flower species!
The past couple of years have been a real trial with family issues and the cyp collection has rather suffered.
I have probably lost about half the pots. Nearly all have been to rot where the plants just do not appear after winter, despite being kept dry. Some is probably down the the size of some of them. I can confirm that as Michael Wienert says, plants that grow in size seem to become more susceptible to rot.
Anyway on the up side I now have plenty of room for all the plants on the staging behind the greenhouse and they can spread out without being squashed up.
First to flower this year was formosanum although there are probably only half the growths of last year.
Next is Michael alba and this is one plant has has held its own. About 22 flowers this year.
I grow the plants on the concrete behind the greenhouse last year rather than on the staging.
With the wet spring this meant quite a bit of slug damage. The reginae types were fine with this but none have appeared this year. Maybe it was too wet for them.
The big macranthos type hybrids ( Philip, Lucy pinkepank) are still fine and getting pretty big. Both Michael clones are well.

They still look great, David...I like the bigger pots...the hybrids are a lot tougher and more garden worthy than most species, except for Cypripedium formosanum which forms big clumps in the garden...it's starting here now
-
All of the sudden, the cypripediums on my allotment are in flower, and I realise that I must split them up soon, as they are now growing across the path between my raised beds.
Here are:
Cyp Ventricosum Pastel 1 & 2 and
Cyp Sabine Pastel
NB I changed the names following a discussion with Michael Weinert.

Really lovely Maren. Mine don't even have their flower heads on yet.

Karen,
Those are lovely,
David
-
...did you mean Maren?
-
Sorry Maren, I do and my spell checker has just changed it again to Karen!
My iPad only seems to recognise 'english' Christian names.
This time I noticed.
A couple for this week.
First up a true alba Sabine with no trace of colour.
The plant is struggling and has already lost a new growth to rot this year. I may have to repot it soon.
Next is one of the biggest cyps I have ever grown.
This Gabriela is about 2 feet across with 35 growths and flowers. A bit of neglect last year did it no harm,

Very nice plants.
You could add my name to your spellchecker's dictionary.

David your Cyp, Gabriela is lovely. We had a frost last night so had to cover mine up. I am way behind with my Cypripediums.
My computer changes my friends name from Kenny to Jenny all the time. Makes me smile .
Angie :)

A monster philipp which has developed good colour with slow growth in our cold spring.
Now up to about 25 large flowers

Cyps well into growth here.
I'm on a steep learning curve with these difficult plants. Some have done quite well whilst others have gone back somewhat. I think I will need to fertilize more. No flowers at all on C. segawai -I need to try to extend its growing season.
Cypripedium formosanum -Only 3 flowers this year, same as last year.

Cypripedium plectrochilum -only two flowers, one opened early, this one later.
(https://c1.staticflickr.com/3/2813/33515658153_e89263ce76_o_d.jpg)
Cypripedium pubescens -a dwarf form, bought as forma planipetalum but lacking the
"planar" petals.

Cypripedium parviflorum
(https://c1.staticflickr.com/5/4161/34468738862_5d01e2937e_o_d.jpg)
Cypripedium fasciolatum -I have a couple of different clones with different flowering times.

I thought I had lost this last year and so tracked down another, but the initial plant has survived -gone from 4 growths to one. Rebunense seems to be very prone to rhizome rot. I now have them in pots of almost pure pumice with the rhizome barely covered. I keep them just barely damp, cool and in shade.

That's very true David ........but then again yer a lang time deid!
(Carpe dieme!).
Here's another one that dies if looked at the wrong way:
Cypripedium acaule

Cypripedium acaule de-flasked seedlings are sometimes available from Albiflora and other sources. They need to be grown in a free-draining very acidic mix (coarse silica sand/grit, chopped sphagnum moss and very acidic Scots Pine duff). The pH of the medium needs to remain below 4.5, this is achieved using reverse osmosis-treated water/rainwater with 15mls/L of cider vinegar added. The seedlings are grown in a polystyrene vaccine box with drainage holes 2cm above the inner base -which effectively creates a small acidic reservoir.
This is the first year of flowering (only one seedling so far). I suspect that getting them this far has been the easy part.

Amazing photos, Steve! I am constantly in awe of the images you are able to capture. Thought of you, the other day, when I noticed Cypripedium acaule (alba form) preparing to bloom at a friend's woodland cabin.
-
Cypripedium parviflorum var. pubescens forma planipetalum in flower yesterday. About 10-11cm tall. Wishing Steve were here to photograph it.
Weather is remaining cool, 11c today with intermittent showers. Hard to believe but the mid-season magnolias are still providing a show, the Camellias are still looking good -in June!

Two out of three clumps of Cypripedium parviflorum var. pubescens have decided to bloom this year. Nice to see a bit of petal colour variation between the two plants.[attachimg=1]
-
A friend's Cypripedium reginae seems to be enjoying the weather here. How it managed to get through last year's record drought is a mystery. Lost count at 50 flowers, long overdue for division.
john - +14c, drizzle & fog
-
I bought a Cypripedium reginae from a local garden centre last year, split it into 2 plants immediately and have been somewhat surprised to find that not only have I not killed them (yet) but one has flowered this year (in very dry East Anglia). Whether I will ever get the opportunity to lose count of flowers remains to be seen...
