don't know if it would work with ornamental grasses, but I have an extroverted gardening friend who often asks homeowners if they'd like her to clean up their overcrowded flower beds & divide their perennials, irises, etc.

& she takes the surplus plants home!

At just about time of year, I stop at the different restaurants, malls, etc that may have ornamental grasses I like. I carefully just snip of a few seed heads, and plant them at home. I get about 50-60 percent germination. :-) Since they are prechilled, they seem to have no problem germinating.

Over on the winter sowing site people are talking about starting grasses. I guess they do them earlier due to taking longer for grasses to get going.

GREAT idea Puzzle!
