David, how are you able to get plants right now?

Certainly one that I would test with Agdia strips.

SlipperTalk has some excellent chains about outstanding white Cattleya hybrids. Searching Bow Bells and Bob Betts will bring up most of these. A few months ago, I found that Shogun Orchids in Hawaii had a division of Cattleya Bow Bells ‘White Sands’ for sale with a mature growth in sheath that...

I was surprised by how thick and relatively short the pseudobulbs seem to be. The leaves also seem wide and thick. Is this from the culture or is it genetic?

The leaves certainly scream tetraploid!

Is this a division of the ‘Waldor’ cultivar that got the 89 point AM in 2022? Your sepals and petals are more lavendar than the award photo; the veining does not show in the award photo. Nicely grown. It doesn’t look like Waldors could get more than 2 flowers per inflorescence.

It seems like line breeding and polyploidy in a number of Cattleya species can produce flowers that rival awarded hybrids!

The petals are wide. Hard to believe it is pure purpurata.

That is why I have found Orchids Roots easier and faster to use. Plus, if you register (free) you get great information on ancestry and progeny.

The issue in Orchid Roots with the second one is that it is Laura-Lei Quintal. The dash matters in the search. Probably also want to be sure the tag has the dash. My understanding is that Orchid Roots is a direct feed from RHS, but I don’t know if there is a little lag time.

Is that three flowers on the one inflorescence, Leslie?

It will be great. I saw an awarded Lovely Lynne picture recently and it was not as nice as some of yours.

Orchid Roots told me that (Fall River x besseae) is Acker’s Flame. However, I don’t find that Laura Lei Quintal itself is a registered hybrid.

It is more than just the technology. It is also agreeing on what is a definite species. Only wild collected plant (not so easy with a number of species anymore)? Is it line bred plants from certain reputable breeders who don’t make mistakes with labeling or flasking? How many definite species...

I think the windowsill gave you a natural decrease in day length, light intensity, and temperature. You likely had lower humidity as well which gave overall less moisture to the plants even if you were fertigating as usual. All of this was enough to trigger inflorescence.

C. warscewiczii is different. At latitude 6 N its change in day length and light intensity is modest. It also has almost steady temperatures during the year. What it has is drier few months in mid-winter. This may be what triggers inflorescence. So a modest dip in day length and light intensity...

David, with the proviso that in-situ natural habitat conditions do not always produce the best flowers, purpurata is an outlier in the unifoliate Cattleya group. It is native to a narrow coastal stretch of Brazil that the Baker culture sheet says was originally about 750 miles long. Much of the...

That would be roughly 120-130 peak photon flux density, which would good for Phrags, even a bit high for many Paphiopedilums, but too low for Cattleyas.

That is great coloration - I like it better than ‘Pizzaz’

It is almost identical in coloration and configuration to my non-fragrant fischerii that comes from a line of sib crosses done by Orchids Limited. The orchid world has been confused and in conflict about species since the earliest days. It will be a while until sophisticated genetic tools will...
