If I take a typical plant (such as e.g. a rosemary plant or an avocado sapling) across the equator from Florida to Brazil and back every year, so that the plant experiences Spring in both places, will the plant experience two growing seasons? Or is there some genetic wiring in the plant to prevent this?

    $\begingroup$ Is this a theoretical question? Because if you live in Florida, you would probably know that you can have already two growing seasons there. $\endgroup$ – benn Jul 19 at 15:02
  • $\begingroup$ Oh, can you elaborate on that? I don't live in Florida, so the question is theoretical in that regard--but the question is a practical one. $\endgroup$ – user257566 Jul 19 at 18:21

    $\begingroup$ I mean, please ask what you really want to do, instead of describing a hypothetical situation (in places where you don't live). Just ask, I have this plant, I live here and there, how can I do this or that with it? You'll probably get a better answer than for this question, don't you think? $\endgroup$ – benn Jul 19 at 21:18

    $\begingroup$ I’m voting to close this question because this is an hypothetical question, while this community wants actual problems (see tour). Or it would be better placed on stack exchange biology, since it is theoretical and has nothing to do with real gardening. $\endgroup$ – benn Jul 20 at 11:32

    $\begingroup$ @dandavis: Plants take cues from the environment, so they might need a certain amount of cold, or other cues, before breaking dormancy. This is something that you might expect to evolve in order to avoid the effects of an early cold snap in the fall. In fact, many plants do require a certain number of "chill hours". See e.g. ucanr.edu/blogs/blogcore/postdetail.cfm?postnum=16468 $\endgroup$ – jamesqf Jul 21 at 16:06
