Doellingeria umbellata
flat top aster, tall white aster
(Aster umbellatus)
The nectar and pollen of this plant attract both long- and short-tongued bees, wasps, flies, butterflies (including the Harris's Checkerspot butterfly), beetles, and other insects. This tall, late-bloomer is as visually striking as it is ecologically useful.
