I have not had a lot of success w Alsto's yet. I have not given up. I hear they are mostly unhappy with cold and wet, not cold. Thats from a zone 7-8 perspective. Under unheated glass in winter may be there favorite place? I also note the ones i gave some shade seem to be doing better - maybe they stay dormant longer and do not try to grow in the coldest wettest time?
