How long lasting outdoors

Can a mj plant last more than just one harvest? If you just snip the buds off and leave everything else, will it come back the next year when it's not frozen? Is there a strain that comes up after froSt times are over and continues to grow bigger and bigger?

The short answer is No. Cannabis is a annual just like a tomato, squash or pepper.

Or a gopher.

Depending on the strain, it is possible, but consider a few things first. Most plants can't make it past the winter, so a majority will die from the cold. Those that make it through the winter have been thoroughly stressed, but are still alive. Once it warms up, the plants will go into flower since the early spring is about 12 hours of light, but after a month or so will revert backinto veg because the days are getting longer. A month or more after solstice, the plant will start to flower again, ready for harvest in fall. To recap- 4 months of deep freezing, flowered, reverting to veg, then flowering again. These levels of stress will cause a plant to hermie, no two ways about it. Any story I have heard of a plant that keeps coming back turns out to involve a hermie with heavily seeded buds. So yeah, it can be done, but when you consider the outcome (and the fact you have a 20 foot pot plant to hide) it is best not to do it.

if u start a plant before last frost and switch to outdoors will it be able to harvest in the summer since it goes right into a 12/12??

Again the answer is no. Since the photoperiod (daylength) continues to increase during the spring months all the way to summer-solstice, the plant would simply switch to a vegetative mode until it nears 12-14 hrs of daylight depending on strain and phenotype. The so called "Autoflower" strains are somewhat independent of photoperiod and can flower in the early-summer for a earlier harvest. This is done by breeders by crossing with ruderalis strains that have adapted to the shorter growing season of the upper latitudes. Since cannabis is not a perennial or "woody" plant, it cannot tolerate frosts/freezes for more than a few hours much less a few months, no matter the strain.
