I've actually been away from my plants for a couple of weeks. It's amazing what you find when you step away from staring at them every day!
Twinkle has 2 pseudobulbs! Before I left, only the one closest to the camera was growing. If you look behind, you see a second pseudobulb! This is so exciting! I'll have at least two sprays of flowers when they mature since they only send up stalks from new growth! Twinkle has been sitting in one of the south facing windows and it looks like it likes the added light!
