I am actually in Colorado, I am interested in the zone(s) in Eden. I am designing a landscape there and want to plant accordingly. I, also, am interested in a list of noxious plants, I'd like to avoid them. Thank You!



The Ogden Valley is a zone 3.  

Our Noxious Weeds are:
Purple loosestrife, Russian Knapweed, Diffuse Knapweed, Spotted Knapweed, Squarrose Knapweed, Yellowstar Thistle, Canada Thistle, Musk Thistle, Scotch Thistle, Perennial Pepper Weed (Tall Whitetop), Hoary Cress,(Whitetop) Dyer's Woad, Quackgrass, Bermudagrass Meduahead,  Rye Johnsongrass, Field Bindweed, Leafy spurge.
