Last night I found myself wondering about the relationship (is it linear?) between dormancy and death in a rose. I think when some plants (maybe Hostas) are water stressed they simply retire early into dormancy and then return in the next season (with water of course). I also remember in nursing school being taught that surgical anesthesia puts us into a state that is as near death as possible (from which we can hopefully be brought back). And, so that all makes me wonder whether dormancy is just a pre-expiration for the plant until the necessary requirements for its life are restored (heat in particular) and ....
okay, finally the practical part of my question: IF at the very end of the season a rose were not watered would it simply go into dormancy early and be likely to return in the spring, or would it simply die.
