Now that the five-month inferno called summer is over, it’s time to for fall planting in the American Southwest. Perfect time to get landscape and garden plants established before next summer. My favorite sources for landscape plants and seeds? Here goes: Trees for Tucson, Desert Survivors, Tohono Chul Gardens, Pima County Master Gardeners, Spadefoot Nursery, Native Seeds/SEARCH, Pima County Library - Seed Library, Terroir Seeds.
