This year I have had a lot of antirrhinums grow between a path and fence that I haven't planted they just appeared. I now see that they have seeded and there are some nice sized plants growing. Should I leave them will they last the winter and flower next year?
I have some come through most winters. More reliably where they're grown hard, no food, no water, dry soil. Soft ones might go under in a hard winter
