Nut sedge is pure hell for an OCD gardener!
unFortunately, while I try to get rid of it, the dogs eat it elsewhere, and I get the seeds!
Bamboo......Oh, yes, I brought a variety that spreads, grows to unreal heights, but put in a larger planter. I gave some to a neighbor 20 years ago.
Still, they cant rid themselves...it sends runners across the property, on the other side of the house, neighbors too!
I grow a few varieties, clumping, of course in the ground. Dwarf Bamboo, Papyrus, Chestnuts, Asian Spinach, Plumeria.....and on. Mostly as Specimens, as opposed to an organized garden. I add my herbs into the landscaping.
