If this is the "other" chart, you mean, I think neither really supersedes the other. One is based on tests in CA and the other based on tests in Australia, using different grafting techniques and potentially different rootstock sources that may not be genetically identical even if they are allegedly from the same nucellar seed line. Any discrepancies are probably down to those kind of differences.

I've often seen it said that key limes are among the least cold-tolerant of all citrus, and they do seem to die rather quickly during even a brief exposure to "hard freeze" temperatures. But in my mostly unheated greenhouse here in the "cool mediterranean" climate of Seattle, they seem to be among the most tolerant of non-freezing but persistently cool temperatures.

Whereas mandarins, Persian limes, and lemons get a sickly yellow color after months on end of lows in the 30s-40s and highs often in the 40s and rarely above 60 (all in °F), the key limes not only stayed dark green, they were the first to push a new spring flush.

Has anyone else in cooler mediterranean climates noticed this? I was mostly growing these seedlings as a novelty, but after seeing their performance for a winter in the greenhouse, I'm thinking I'll put one in the ground in there permanently.

I've not had it myself, but pretty much every time I've seen it under discussion people have spoken very highly of it. Whether compared to Meyer, Pomona, or Ujukitsu, NZL seems to always come out on top.

The Sangue e Latte wood I got was from Italy, and it took off identically to when the donor tree did over there. I look forward to seeing how it grows this season.

Thanks!
I'll start root chopping!!
