I've never seen another, ever since the one I had years ago. I took cuttings to send to you, but neither them, nor the main plant ever made it. I found this Philo to be a very slow grower, even under optimal growing conditions. Yours looks like a very healthy cutting.

Photo, I got mine off a Facebook plant group. I paid $20 ( shipping was included). And it is very healthy, it was already rooted, thank God!

When you say it grows slowly, like Draceana slow? Lol.
