I got a big pile of seeds from China. Most are veggies and I recognize the seeds as such. Some in the list were bad and I had intended to throw them in the trash, but whoever processed the order, gave me a different seed mix so I didn't get those - just the bad yellow iris, I think. I will start 3 seeds and see if they are the naughty ones. They can have their own corner with the raspberries and easily go away if they are.
We have the dreaded Japanese Knotweed all over Maine. It is a horrible invasive.
