Elliott’s aster (Symphyotrichum elliottii) is the absolute last of our asters to flower at JLBG. It doesn’t begin to flower until the first of November and withstands the mild frosts of October like they didn’t even happen. It is naturally found in tidal freshwater marshes and other moist open sites from the Virginia and Carolina coastal plain south to Florida and west to Louisiana. Though it hails from moist environments it thrives under general garden conditions if the soil isn’t allowed to become too droughty.
The plant has a lot to recommend it besides the time of flower. It forms stiff stems rising 5-6’ tall crowned with a dense pyramidal arrangement of inflorescences of pale pink with a hint bluish-purple ray flowers and bright yellow disk flowers. The lack of lanky branches allows this tall aster to display its flowers without flopping all over the rest of your garden in the manner typical of asters. It spreads via rhizomes, so you need to be sure to give it space to roam a bit. It provides a dramatic impact when planted at the back of borders. Though it spreads, it doesn’t roam far from the parent plant and can be easily kept in place by yearly thinning of the outer edges of the clumps.
The most outstanding feature of this beautiful aster to me is the number and diversity of pollinators it supports. I don’t think I’ve ever seen a plant that attracted more. In addition to swarms of honeybees, bumblebees, carpenter, and solitary bees the flowers draw in numerous pollinating flies, halictids, moths and skippers. I love plants that extend the color season and though we all think about early spring, we really should also plant to extend our love affair with color into the leafless season and Elliott’s aster does this is a big way.
