Post by: Florian on January 24, 2019, 07:24:01 AM
Seen today in Montreux (CH), any guesses?

Looks like a Thomasville.

A hardy citrus growing outside in Switzerland, near Lake Geneva, with a slope behind it.
Is that stone wall facing South?

Ilya, is your Thomasville trifoliate? Mine is exclusively monofoliate.. ???

Socal2warm, Montreux is one of the mildest places in Switzerland north of the alps.
The wall is indeed facing south and the little tree is only a couple of metres away from lake Geneva.
I guess that a Satsuma would survive most winters there unprotected.

Lower branches  of  Thomasville as well as strongly growing new shoots have trifoliate leaves, while on the top and on flowering twigs they are single.

Ok, I see. That makes sense. Mine is grafted. But then I am not convinced the above plant is Thomasville since almost all of its leaves are trifoliate (although on some the two side leaflets are very small).

Longer middle leaf suggests mandarin background  http://fshs8813.wpengine.com/proceedings-o/1999-vol-112/54-55%20%28BOWMAN%29.pdf (http://fshs8813.wpengine.com/proceedings-o/1999-vol-112/54-55%20%28BOWMAN%29.pdf)

I am also not sure, but the closest  thing that I have seen is Thomasville. This plant, obviously low grafted on poncirus is way too vigorous.
