Phalaenopsis - any way to identify the most/least cold tolerant ones?

[Delila]

Hmm, that's quite a database. Because most Phals are multi-generational hybrids, I guess I was hoping that some clever person might have figured out general cold tolerance guidelines according to e.g. Leaf shape/thickness/colour, root style, flower type, etc.

e.g. Violacea types are fairly recognisable, and I assume they have poorer cold tolerance. Certainly none have ever made it through my winters to date . So anything vaguely resembling them I will try to keep warmer...somehow!

There is no general way as you expect to classify warm and cold growing plants. Databases like Orchidwiz can tell you the individual species composition of a hybrid and based on the average will predict the growth conditions, though helpful, this technique is flawed as the characteristics that are passed down from each generation to the next are variable. For eg Phal. lindenii is a cold to cool growing species with mottled foliage, this plant when hybridized to Phal. Silbergrube (equestris x celebensis) which has spotted silver foliage, produces a plant that has foliage exactly like lindenii and flowers very very similar to lindenii but this plant does very well in warm climates.
