Last Call
As fall color, the caution-yellow flowers of rabbitbrush tend to flare early. They bloomed here, this year, weeks before the aspen or the scrub oak got around to changing. As a wildflower, though, rabbitbrush blooms late, which is why plantswoman Lauren Springer Ogden refers to it as the “last bar open”: a destination where insects gather for one final slug of nectar before the season shuts down.
