I got this at Painters Greenhouse in Old Fort a few years ago. I love the pink side of the leaves.

To my frustration, keeping it inside wasn’t keeping it pink, though. It gradually lost the significant color difference. I assumed that it was similar to my black elephant ear and simply needed natural light to brighten up.
I had pinched a piece to root for a friend and as it grew roots the leaves that actually had been slightly pink died. So, by the time there was enough root to stick in dirt and I was going to see her soon, it just looked like a regular syngonium with the barest blush on one side of those leaves.
I took the big pot outside when I potted the cutting and left them both outside for a while, hoping they would have the same dramatic response the Colocasia had. They didn’t seem to do anything, though.
When I picked up the pot to take to my friend, it had a new leaf and it was vibrant. The other 3 were still just green. I told her how it had behaved so that she could know what to expect. And she suggested that the planted needed the light to produce pink leaves rather than to change the green to pink. And, looking at the new growth on my large plant, that seems to be the case.
So, all color change in non-green leaves is not the same.
I have learned a thing.
What do you think?
