that outdoor one is beautiful in person! It's naturalized, wild cannabis. It was not planted, it came up from last year. I'm wondering if it could have over-wintered in the ground somehow, it's in the exact same spot as a female last year and I don't think @99PerCent pollinated that plant.
We had a run of about 10 days with zero-degree temperature at night last winter, hard to believe it could have over-wintered. But if the ground was being kept warm somehow by composting maybe it could have lived? The trunk (stem) of the plant is especially large and tree-like.
Let's ask Ed! I have read about travelers to Afghanistan reporting cannabis or hemp trees 15+ feet tall that are many years old. Down in the foothills where temps are milder. They go dormant in winter and grow again in spring.
