Accidental cloning

I did my first harvest a week ago , did some trimming before cutting it down and left some plant parts in the pot .
Pulled the root ball and gave the left over soil a stir up then left it out on the patio and sort of forgot about it.

Was doing my yard work this morning and gosh darn it if one of those cuttings didn't take root and now looks like a rather healthy little plant .

So is it worth keeping ? My brain says probably not because it's going to be in flower mode from the start but I may be wrong

If it has rooted and the days are long where you are, it will be re-vegging. If you need the pot for another grow, maybe transplant the cutting into a smaller pot. I say let it grow : )
