There are 30 species of Dalea found in Arizona, many of which are the the nursery trade because they are so doggone pretty. How cool is that? Very. Feather bush (Dalea formosa) can be found in lots of different plant communities around Arizona, New Mexico and across the border into Sonora and Chihuahua. It sure seems to like warm rocky rubble wherever it is and the gravelly plain at the base of the Dragoon Mountain fits the bill. The photos are mine and taken on the aforementioned gravelly plain.
