Symphyotrichum lanceolatum (White Panicle Aster) is a robust herbaceous perennial boasting numerous branched stems smothered by sprays of tiny star-like white flowers in mid summer to fall. Rising from the stem tops and upper leaf axils, each blossom features 20-40 white rays surrounding a center disc packed with pale yellow disc flowers. The disk flowers change from yellow to reddish with age. The blossoms are pollinated by bees, butterflies, flies, beetles and moths. Blooming for 4-8 weeks, the flowers are followed by a dry seed (achene) that matures in late fall and is distributed to new locations by wind. The stems are clad with alternate, narrowly lanceolate leaves, 5 in. long (12 cm), sometimes irregularly toothed along the edges. Medium to medium-dark green above and paler below, they significantly decrease in size as they ascend the stems. Native to wet prairies, low wet depressions and along streams of North America, White Panicle Aster is easy to grow, low maintenance and is not affected by any serious pests or diseases. However, it can spread aggressively by rhizomes and form dense colonies. It is best used in moist prairies and meadows.
