But I got to wondering if it might perhaps throw some seeds out and spread that way? I guess if I do plant it, I need to cut off any flowers that form? I SURE don't want any of that stuff in my yard...my neighbor mentioned once that she was thinking of planting some at the back corner of her yard (which borders mine and is right next to my compost pile and a "wild" section of my yard that I don't mow) and I threatened her life! (We are good friends...she didn't do it, thank God, or we might not be!)

Anyway, I just thought I'd check first and see what everybody here thinks of my idea, if it would be safe?

Bamboos do pretty well in pots. If you are in an area where Winter freezes occur be sure to get a variety that can handle the cold or protect it. As for bamboo being aggressive you can find varieties that do not "run". They are known as clumpers since they send a shoot out an inch or so then produce a cane. This does not always apply but as a rule of thumb if the cane has a flat spot in the round of the cane, it is a runner. If the cane is perfectly round, it is a clumper. I have some that I planted four or five years ago that were in gallon pots. Now they cover an area of about three feet in diameter each but are about eighteen feet tall. The luxury of it is that you cannot see through them due the amount of canes is such a small area. They make a great natural fence. I have yet to see bamboo bloom but I know they will and produce seed. Most varieties die after a bloom which causes problems for Panda Bears in China. A whole grove will bloom then die leaving the Pandas without their main source of food. (little trivia)
