Happy New Year: I'm looking for the whole-world version of the chilling hours map. http://raintreenursery.com/indexpics/… Could someone give me a hint please? I would like to try the bulbous species which might have less chilling hours than the others. And sorry that I just can't find a original map from the university. Only from the commercial web. Kind Regards It's our coldest time in a year. 12 C around 53.6 F Fierycloud, Taiwan (USDA Z11+ , AHS Z12+)
