Hi Peet,
Welcome to Permies!
I have heard of Vetiver grass, but think it suited to warmer climes than mine! I am trying growing Miscanthus at the moment for biomass. One of my plants is starting to increase, so a qualified success there....
Welcome to Permies! So nice to meet you. I wish you great success as...autumn begins there? (Spring is in full swing here! Melons getting planted in a week or so!)
