I am interested in creating a prairie inspired landscape in my smallish backyard. I would like to use a variety of ornamental grasses with a minimal number of flowers. I have heard that large flowering plants are better for allergy sufferers, because they use their blooms (rather than profuse amounts of pollen) to reproduce. I am the kind of person who takes two daily medications for allergies and am allergic to grass, trees, pollen, etc. Does this mean grasses will cause me fits? I would be grateful to anyone that can 1) tell me whether grasses are bad for allergies and 2) give suggestions about grasses that might be better for allergies. (And that can survive Wisconsin winters!) Thanks!
