I have a rosemary plant that is about 20 years old. I live in zone 6 in Vernon British Columbia. I bring it in when the nights get to 0C 32F. I leave it by the basement sliding door with a south exposure. It blooms 2 or 3 times a year and has not been repotted for over 7 years. It reseeds itself on top of the compost that I add every year. It is outside now and just starting to bloom again. I plan in repotting it next spring by cutting some of the roots and pruning it.
