U. warburgii in zone 7

Though last year especially was quite cold, and the average high is significantly lower here, my usda zone 7 conditions aren't terribly unlike Utricularia warburgii's home climate in Zhejiang, China (boy the searching I had to do to come up with more than "found in China, where it grows in sunny wet meadows at an altitude of 900 m").

Moral of the story, after 3 years untended in my sarracenia tray, i found a pot with U. warburgii alive and well. I dont know if it has flowered outdoors, just that it survived freezing temperatures quite impressively. Looking forward to learning more.

I'm surprised that it will take such cool temperatures. Interesting.
