I'm afraid that weed needs in warm climate: south USA, Jamaica, east, south Europe... Anything what would grow northerly would not get the same effect.
This is not a miracle that something would grow.
But this is like trying to cultivate waterlemon in the north.
It would be small like tomato, green like it happen with waterlemon at the beggining of summer in the south and no more.
IMHO, No way.
You know what is the difference between weed in the north and weed in the south.
In the south it is like
tree!
In the north it is grass on the belt.
Only special greenhouses will save.
Not that kind of seeds.
