I wish I could have started before and after pictures for this Prayer Plant! I've had this for nearly 20 years. Up until 2 years ago, it was 24" across and would bloom every August (lived in MD). I moved, and within a year or so it stopped thriving.The house was a lot darker.
I moved to Florida in February of this year, and by then, it had only 3 leaves left (the 3 dull ones in the pic). I placed it on the patio after the night time temps remained above 58, and it has produced 6 new, even more vibrant leaves, with 3 shoots popping up beneath them. All within 2 months! I'll post another pic 4 weeks from now.
