I haven't, no, though I did have a hemp plant one year, which isn't the same as sativa sativa, but looks vaguely similar. Hemp seeds are included in bird seed mixes, so what she has may actually be hemp rather than sativa. Personally, I'd just be grateful if one grew all by itself... but that's another story, lol. It is tender, proper cannabis, and wouldn't have survived the winter as a plant, so I'd imagine this isn't really a true cannabis plant.

I found it growing in a window box once, brought by the birds!! I agree it is a very pretty plant It got pulled up and thrown away!!

Lol Bamboo!!! oh you made me laugh. Didn't know hemp looks similar, Perhaps thats what it was then!

I do think it was a cannabis plant they are tropical and tender therefore they would not survive our climate and if it was cannabis plant I would destroy immediately properly by burning it.

if it is be careful you dont have a nice blue bottle in civvies that walks up and down your road they have a strong nose for that sort of thing.
you dont really want her to get into trouble, best thing pull it up recycle it

"a nice blue bottle in civvies", well I must say, that's unlikely in London these days, policemen on foot, uniformed or not, are rare as hen's teeth...

yea but i actually do have them living in my road
