But you have to pluck them first.

Another problem with eating grass is what else might be on it. Pesticide, fertilizer (both processed and 'raw') and intestinal parasite eggs. Always wash your grass before you eat it. Don't wash it before you smoke it or it won't light.

I eat chives right out of the garden, and nasturtiums. I haven't gone for roses yet, but they're better for my eyes than for my stomach. I believe squash blossoms are edible, but they're also too pretty to eat, IMO.
