That looks like a marijuana plant to me too. What do you want to do with it? It may be a male (worthless) or a female. Do you have a place to stash a big eight foot plant. It will get big. If its a girl chances are you will have a nice little harvest come October. If you can keep it safe until then.

Does anyone else know about your refugee plant? They may have the same idea as you so better think fast.

I have always likes refugees. Just the fact it lives and shows you it wants to beat the odds. It clearly needs a home.

One last thought, do you have any natural occuring marijuana plants in the area? If you have weed growing wild in your area it could be an old rope plant. In that case chances are good that the plant has very low THC and is not worth the effort.

Whatever you do good luck.
