I agree. One of the best Cattleya species of all time!!!
I think it is the pinkish lavender color, large flowers on a compact plant. But what sets it apart are those raised, golden yellow keels in the throat.
David,
Thanks for asking.
I grow in an unheated GH on the coast in Bolinas ( just north of San Fracisco).
Winter nights down to 40 F Summer highest 80s F.
I am able to grow mounted due to proximity to the Northern California coast where I don’t have to fight for ambient humidity.
Plant hangs in good but not too bright light maybe 2500 FC summer.
I water/hose spray approx 2 x week in summer less in winter. And if I’m lucky I can feed every other week.
Our water quality is generally good 180 TDS Winter - Spring can reach 250 in summer.
I’m going to the GH tomorrow and will add to this post if I see more details tomorrow.
