Variegated leaf porn

Whenever I put the word “porn” on my blog I get lots of hits. I need all the help I can get, so as a sort of follow-up to my post on the science behind variegated leaves, here’s some variegated leaf porn from Roger Williams Park Botanical Conservancy in Providence.

I have no idea what any of these plants are. Any ideas anyone? Jo-Ann B., if you’re out there chime in because I know you know the answer! I think it’s the coolest thing ever that the leaves are variegated green/cream on the top side, but all purple on the bottom side. Very wacky things going on with pigments and genes here.

Below is an example of a plant that lacks chlorophyll (green pigment). It has instead an excess of the anthocyanin, the pigment that produces reds, pinks, and purples. Posted by: Caroline Brown    Source
