Fort Collins-based Colorado Native Plant Society was established in 1976 “to encourage the appreciation and conservation of the native plants and ecosystems of Colorado.” It has chapters in Boulder, Denver, Fort Collins, the Western Slope and southeastern Colorado. CoNPS holds a native plant sale every year. Visit conps.org, place your order by April 15 and on May 4 pick up your plants at either Boulder, Colorado Springs, Littleton or Loveland.
