Not the D. spatulta or P. leilani, but the other two pings. The one on the left was referred to as mexican butterwort, and we are clueless on the other one on the right.
The "mexican butterwort" flowers are hairy, large purple margins and white interior. I think the tail was white too, but I cant say for sure. I have successfully propagated it many many times off its carnivorous leaves, too. I havent seen a winter rosette, and its been 2 years. Safe to say it doesn't have one.
The other has a winter rosette, this one's a baby compared to others we have. Summer leaves are longer, ~3-5in on the largest one. Basal winter rosette on that stays around 1.5-2in diameter. I think the whole flower is purple...? But im not sure. Also successfully propped this from the summer leaves.
Point me in the right direction and maybe I can figure it out! They were donations from a botanical garden forever ago, I dont think they are cultivars/crosses but I am unsure.
