September in an Arizona native garden
September is a quieter month in Arizona: 50 of the state's 127 native plants flower in September, compared with 98 at the June peak. That makes these plants valuable for keeping color, and food for pollinators, going outside the main season.
17 finish in September, including Butterflyweed, California poppy and Candy barrel cactus (fishhook barrel), so this is the last chance to see them in flower.
45 of them grow in full or partial sun and 9 tolerate shade, so there are options for open beds and woodland edges alike. Sizes run from low plants like Antelope-horns milkweed and Aspen fleabane to trees such as Desert willow and Jojoba. For wildlife, 40 support pollinators, 25 provide food or cover for birds and 14 are caterpillar host plants.
32 of the 50 have a seed or plant listing we verified as the wild species. Be careful buying Apache plume, Common yarrow, Harebell: common listings for these are often a bred variety or a different species.
Good places to start
Verified wild-species listings that take sun and are widely native, so they are forgiving first plants.
