The message

from sutartsorric contains these words:

Didnt some botanist prove the Ash always comes before the Oak, because
the Ash responds to temperature while the Oak uses day length?

Given the low temperatures we've been having, I would have thought that
the oak would win. Thinking about it further, if this was the case,
surely in the frozen north, where day length gets longer than in the
south, the oak would always win!
