Cattleya trianae and percivalliana

[monocotman]

This trianae is the one that I featured last year as a four year demonstration of bloom changes and improvements. It’s continued to grow with four new pseudobulbs this season, three of which and flowering.
Chadwick writes “But it is the many delicate pastel shades of color that set C. trianaei apart from the other Cattleya species.” I have to agree. The pale pinky lavender is really beautiful.
I dropped the plant earlier in the year when it had two new growths and broke one clean off. Fortunately it broke two new leads from older growths and so now have three leads. It’s very vigorous and loving the new growth room.
Next is Cattleya percivalliana albescens ‘oro blanco’. A plant making steady progress.

wonderful flowers!!!!

Blooming now David, a little early? What conditions do you think cause the inflorescene to develop?

This summer was hot, many of christmas flowers are in bud at me, too.

Terry, who knows with my conditions?
I am cutting down the lighting and the night temps lows are approaching 15c when it’s cold so hopefully things will be back to more normal flowering times next year.

the 'white' is very pretty with the faint colour in the lip

Both sets of blooms are stunning

Wonderful!

You are suggesting that the temperature change induced the inflorescence to begin growth? It makes sense that it is some combination of day length change and temperature change that does it. If the drop from hot summer to normal autumn occurs, the plant could begin early.

It wasn’t that hot in Cornwall this summer but the plants did get long days under the LED lights and temperatures in the mid twenties. Growth was good. Plenty of plants made two successive growths. I think I still need to play around with the conditions in the growth room just to optimise it. Flowering is generally early for some but I still have a labiata just showing buds and other trianae are not yet in bud.

I suspect there is good variability of times of flowering, new growths, and rooting in the natural environment. Not healthy for the plant population to all flower the same week. It makes them too vulnerable to weather and predators. We shouldn’t expect to get all of any species to flower at the same time.

Lovely Cattleyas, especially your percivaliana.

Terry, some species are growing and flowering fairly normally such as labiata and lueddemanniana. With gaskelliana and mossiae, some clones are flowering and some are not. All are producing sheaths. With warscewiczii and hardyana, most are not producing sheaths although growth is good.

Now that storm Bert has finally passed and the weather is a bit better, here is a nicer photo of the trianae outside.
