Outstanding Qualities

A lovely North American native, the white wood aster rambles and tumbles through the garden bed. In late summer a profusion of lacey small white flowers top the lax purple-black stems. The frothy flowers peek out from between its neighbors and weave the garden together. This is one of the few asters that will also tolerate some shade.

Culture Notes
White wood aster thrives in light to open shade in rich well-drained soil. Once established it will grow with only occasional watering. Although it may produce seedlings, it does not become aggressive in the garden. Resist the urge to stake it, or you’ll spoil its carefree appearance. Allow it to mix and weave through other garden plants.
