Did you know Plumeria acquire different levels of Dormancy?
Dormancy levels vary between plumeria. In general, the
number of plumeria that may acquire dormancy shows a trend
to increase with geographical distance from the equator and correlates with the occurrence of seasons.
Variation can also be found within plant species. This has been
studied intensively in the model species Arabidopsis thaliana
(Arabidopsis), which is widespread in Europe and parts of Asia.
and shows high variation in dormancy levels

Did you know spider mites go dormant during cold weather?
spider-mites have learned to go dormant when the length of hours of daylight start getting lower, seemingly aware that cold temperatures will soon follow. Other factors enter into it, such as temperature, but photo-period appears to be the main cause. The specific amount of hours of daylight required to bring on dormancy varies according to latitude (farther north, where it gets cold early, they go dormant sooner), but it’s somewhere in the neighborhood of 13 hours a day of light everywhere. They don’t all go into diapause at that same exact time, either, as individual spider-mites have quite a variance in their response to these stimulations.
