In the Intermountain , Southwest and western Great Plains, the summer rains have brought the native summer and fall blooming plants into their full glory. This also coincides with the hummingbirds’ southerly migration down to southern most AZ , NM, TX and Mexico . Not coincidentally, this brings their favorite nectar sources like the Hummingbird Mint (Agastache), Hummingbird Trumpet (Zauschneria) and Sage (Salvia) into flower. Other natives plants like Perennial Sunflower (Helianthus), Asters, Joe Pye Weed (Eupatorium), Gloriosa Daisy (Rudbeckia), Goldrod (Solidago), Vernonia and all the incredible warm season grasses like Muhly (Muhlenbergia), Sprobolus, Prairie Switch Grass (Panicum), Little Blue Stem (Schizachrium), Grama (Bouteloua) also come into their full glory. Many Old World shrubs and perennials like Russian Sage (Perovskia), Butterfly Bush (Buddlleia) and re-blooming English Lavender and grasses like Chinese Maiden Grass (Miscanthus) and Fountain Grass (Pennisetum) throw their flowers into the ring as well.
I’ve been trying for many, many years to convince gardeners, who don’t already appreciate the glory of fall, the flowers don’t need to stop when early summer has past. Yes, fall is more than just Mums, flowering cabbage, kale and pansies. These are wonderful plants, but can be worked in with many other fall blooming perennials for an incredible effect.
