@Porat, sorry for the late reaction, i think A.Filifera is much more cold hardy than A.Americana, especially in combination with a higher humidity. My A.Filifera still looks like there have never bin a winter before. A.Americana normal version is R.I.P , A.Americana Variegata is still alive but doesnt look to good.
Greets.
P.s Thank Yonex, i will in the future!
