Detailed Information

Flower: Flower shape: 7+petals Cluster type: panicle

[photo of flowers] Leafy, open cluster of daisy like flowers, ¾ to 1¼ inches across, 20 to 60 narrow white to bluish rays (petals) and yellow button-like disk in center, on a slender stalk to 1½ inches long.

[photo of bracts] Flower bracts are very narrow and over lapping like shingles, in 3 to 5 rows.

Leaves and stems: Leaf attachment: alternate Leaf type: simple

[photo of leaves] Leaves are alternate, lance-elliptic, up to 6 inches long, to ¾ inch wide, toothless and hairless, tapering to a blunt tip and tapered stalk at the base, becoming smaller as they ascend the stem. Stems and leaves are smooth with a whitish, waxy surface. Multiple stems, tall and slender, arise from the underground root-like branches (rhizomes), becoming heavily branched in the flower cluster.

Fruit: Fruit type: seed without plume

The flower produces a small nondescript seed head; the fine seed is nearly plumeless.

Notes:

False Aster is most commonly found in moist habitats along streams and lake shores. The large showy clouds of flowers do not become apparent until late into August, continuing into the fall. It will perform well in the home garden though the root system can be aggressive and require periodic containment weeding. It is distinguished from other daisy-like flowers by the relatively large button-like disk in the center of the flower, and the narrow bracts that resemble one of the fleabanes more than other asters. There are 2 varieties in Minnesota: var. recognita and var. latisquama. As far as we can determine, the subtle differences are in the floral bracts.

This is a spectacular plant for the wet garden area. Another name is "Thousand Flower Aster". When in bloom, it smothers anything underneath it. There is even a pinkish form. I well recommend it for the garden.
