My anceps tanned by the winter sun...but I wonder if it is too much.
My feeling says it's not. It's growing outside benefiting from what I call "anceps weather": low temps (14 to 2ºC / 57 to 35 F) and clear skies with full sun all day (with low RH there's an increase of UV intensity that might explain this color). In the past days I've been sheltering it indoors as there's some frost going on.
Note: the sunburned leaves happened in summer under full sun with temps over 40ºC (104 F).
Enjoy!
