Low was 0F this past winter. Mt. Ginni Debeuzevillei has seen colder but was wind protected. The previous winter saw -14F was wind protected and a string of mini Xmas lights, so low was about -9F inside. It was setback and did grow until late June. I think it died this winter since it was weak and damaged from last winter.

I'm glad to hear your camphora is coming back so fast.

What do you have for trades? I have loads of rhododendron seedlings, Yucca hybrid seed, Tetrapanax. Do you have lacrimans seed?
