We have a number of favorite legumes in the garden, but most flower in the spring or early summer. The star of the fall garden is undoubtedly Dalea bicolor var. argyaea, which starts flowering in mid-October. All summer, we get to enjoy the silver foliage, which thrives in our summers, only to be further rewarded in fall with the floral show. This amazing North American native hails from Texas and New Mexico, where it can be found in alkaline sandy uplands.
