A sudden drop in overnight temperature killed my outside pot of coleus. I had just taken these pictures a few days before. I don't know if I was imagining things, but it seems the pink hues were more vivid than ever, those last few days it had bracing in the cold.
I still don't know why some leaves come out rounded edges
and others the normal pointy shape.
Glad I have more of this pretty in the windowsills until next spring.
