Cyps in pots 2010

[monocotman]

hi there,

it's been a pretty slow start to the season here - I reckon the plants are at least two weeks later than last year.
First up, not surprisingly, is a group of fasciolatum hybrids.
Front left is a new seedling for me - 'Florence' ( not yet registered). This is a 2nd generation hybrid - Gisela x fasciolatum, from Peter Corkhill.
I was hoping that it would have kept some of Gisela's red colouration, but not to be. Two doses of yellow/brown flowers have drowned out the red of macranthos, at least in this clone.
However it is vigorous - three immature growths last year have produced five growths and four flowers this year.
Front right is Victoria - pubescens x fasciolatum. A vigorous second year flowering seedling - two growths and one flower last year increasing to five growths and four flowers this.
The large plant at the back is the Sunny ( calceolus x fasciolatum) that I posted photos of the repotting and dividing of last autumn.
I removed six small divisions, varying from one to four buds and five have appeared this spring, though all are quite small and need at least a year to reestablish.
In contrast the individual stems of the main plant are bigger, have larger leaves and flowers than ever before. I probably didn't remove enough roots for the small divisions.
This seems to be par for the course when repotting and dividing cyps. Some plants sail through without any obvious problems and others suffer a setback and take a year to settle down,
Regards,
David

hey,
I have only one of my "treasures" flowering in pot in the greenhouse.
its a first time flowering of a bunch of Cyp. segawai seedlings.
though beein very small, only 10 cm high,
it makes this flower, a little bit  distorted.

Good morning,
just been browsing through some old photos and was struck by the improvement in the flowers of 'Sunny' over the last five years.
First up is the very first flower in 2005.
Second is the current flower, out now.
The difference is striking - the form, colour and size have all improved markedly.
When it first flowered I contacted the breeder to see if there was much variation in the flower colour in the cross.
Apparently not. I'd seen a photo of Sunny at Werner Frosh's web site and wanted a similar plant with strong brown/yellow colouration.
The improvement appears to be down to a combination of culture and maturity,
Regards,
David
ps goofy - nice segawi  - not one you see offered very often!

Hi,
an excellent new hybrid - Sabine pastel. Probably ought to be called Sabine 'virtually pure albino'.
The first hybrid grex with an almost pure white flower - there is just a few faint red spots behind the staminode. The rest of the flower is pure alba.
It's great to have a hybrid with white flowers - this is new.
Hopefully it will have hybrid vigour and eventually make a nice potful.
I don't know the exact parents that were used. Sabine is macranthos x fasciolatum. There are plenty of macranthos alba clones around but is this enough when crossed to produce Sabine pastel? Are there alba clones of fasciolatum?
There are similar grexes with Gisela/pastel and Aki/pastel, both of which probably used macranthos alba as one of the parents.
Neither of these pastel grexes are as pale as Sabine.
Regards,
David

Afternoon,

flowering for the first time for me is the hybrid 'Iwahime' - macranthos var speciosum x fasciolatum.
Anybody know where this name came from?
Although speciosum is smaller and paler coloured than straight macranthos,the flower is very similar to Sabine ( macranthos x fasciolatum).
There may be more striping in the flower than in Sabine, but it is fairly marginal and there is no difference in the size.
I'll post a comparison photo pf the two in a couple of days.
Still, a nice thing and looks to be fairly vigorous,

Regards,

David

Anybody know where this name came from?

Historical  Japanese Empress/Princess Iwahime.
Now used as the name of one of the characters in a digital wargame, I believe.

[Anthony Darby]

Cypripedium macranthos var. speciosum comes from Japan, hence the name of  hybrid. http://www.w-frosch.de/Cypris/Arten/arten_e.htm

Cypripedium 'Sabine' is actually fasciolatum X macranthos, not vice versa, though I'm not sure if that makes any difference?

[monocotman]

Maggi,

thanks for the information. I believe the plant was originally from Peter Corkhill via Laneside Alpines.
I know Peter had contacts in Japan so maybe he named it for them.

Anthony -thanks - I haven't heard of any morphological differences between reciprocal crosses in cyps, has anyone?

Regards,

David

Good morning,

the star performer for me this year is this plant of the hybrid Michael (macranthos x henryi).
Last year there were four stems and seven flowers, this year there are eight stems and fifteen flowers.
Now it has matured, the plant regularly produces multiple flowers per stem, as does another henryi hybrid, Hank Small (parviflorum x henryi).
It seems to be a good parent for multiple flowers and recessive for flower colour - just as well as they tends to be small, fairly non descript and green.
The hybrids are reasonably fast growers but the stems tend to be a bit on the weak side - probably affected by the number of flowers. In this week's high winds I've had to take both plants into the greenhouse to stop them being bashed about.

Regards,

David

That is stunning. Are you still using the perlite mix you talked about before?

David

Maggi,

thanks for the information. I believe the plant was originally from Peter Corkhill via Laneside Alpines.
I know Peter had contacts in Japan so maybe he named it for them.

Iwahime was not named/registered by P. Corkhill
but by A.Hiratsuka & T. Oyamada in 2008.

Nevertheless your plant might origin from Peter

cheers

Hello,

see my little collection in pots. They all grow in nearly pure Seramis.
kentuckiense, flavum und reginae are on the way!

David,

yes - I'm still using the same mix as before. 80-90% super coarse perlite plus a bit of orchid bark. Then full strength feed from the very beginning of growth. I posted a photo of the same plant last year.
I have a slightly nerdy photographic record of this particular plant from it's purchase as it coincided with my first digital camera!
In 2006 and 2007 it produced just a single growth and flower.
In 2008 there were three growths and four flowers.
In 2009 there were four growths and seven flowers then in 2010 eight growths and fifteen flowers.
This seems to be fairly typical of quite a few of the hybrids. They really don't start to grow quickly until there are between two and four growths. Then doubling in size each year seems to be fairly normal - it can be higher.
Hideki Okuyama ( fasciolatum x ventricosum) has increased from three growths and two flowers last year to eight growths and five flowers this year. Pity the flowers are a bit ho-hum.
The only ones that don't go along with this are the Reginae hybrids with anything except the closely related flavum. Ulla Silkens grows well but the rest I find pretty slow and a bit miffy.
Wouter Peters ( fasciolatum x Reginae) last flowered in 2006, then virtually disappeared the following year and is only now back to flowering size.

Goofy - thanks for the info, I hadn't checked Werner Frosch's list to look at the registration.

Pauli - it sounds like we use a very similar compost,

Regards,

David

David,
I always check the RHS Orchid Register
