I've got my first S. purpurea from Lowes a month or two ago. It was just about completely green when I got it but cold air and bright light hath done it's magic and the latest pitcher is the reddest of all. I like it but shouldn't it be "purple"?
Also, I notice that unlike Nepenthes these don't seem to self fill with fluid. Should I be putting some R/O in them to make them have moisture in the funnel? How long can I leave this in a 2 .5" W x 5" deep pot of LFS? Repot when i move it outdoors in spring to a 4" or bigger?
