I nearly cooked this plant last year with a little direct sunlight. The plant flowered recently, and now it has grown a new leaf with ribs on it. Is it the stress of last year, or is it a sign of neglect due to it being a noid?
It has another leaf barely peeking out, and it still hasn't dropped the 2 flowers that survive. I'm happy that it is growing, considering the torture it has endured.
I've had Phals do that, but not quite so pronounced. It's probably due to stress, perhaps too little water combined with too much sun. It may look a little goofy, but should be OK.
