I have a bunch of Mexican pings that look almost identical to the pictures you posted. However, the flower in one of your pictures was quite different from the ones I get from my pings, so maybe they are different species or different cultivars. Let me know if you want to discuss further. Also, I have some fork-leaf sundews that I just now started from cuttings. They are pretty small, but the plants are pretty easy to grow outdoors here in Dana Point.
