Happy New Year:

I'm looking for the whole-world version of the chilling hours map.…

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
