Last fall, I moved two phals from the kitchen to the patio. Because I was renovating some things.
I promptly forgot about them, and found them again sometime last month.
So they were outside for all of our winter.
Temperatures reach a lovely 28 - 45 at night during January, and bits of February. They sat through the rain, the wind, even the 5 minutes of snow (omg we had snow!) and brief hail.
Despite the cold, I do know that I can keep sub tropical and tropical plants that are supposed to be grown warmer. So some factor I don't now about was obviously helping.
Anyway, suffice to say these phals were grown colder than they should've been.
What I found interesting is that they reacted in different ways.
One, is a phal amabillis. The other is a noid.
Amabillis lost every root, 4 leaves, and suffered a bit of damage. It's produced two basal keiki, and the mother plant has sent out a root. So I'm going to treat this as a happy accident. And look forward to big future displays.
The noid however, suffered very little damage. A few small spots of cold damage, and no root loss. And to my delight, 3 spikes! And one branched.
