- Description
-
‘Blue Danube’ is a cultivar of the native Stokes' aster, which is in the Asteraceae (daisy) family. It is a showy, herbaceous perennial that is named for the Danube River because of its lavender-blue-colored flowers. Growing 12 to 18 inches tall and wide, it attracts bees, butterflies, and hummingbirds and is low maintenance, drought tolerant once established, heat tolerant, and deer and rabbit resistant.
Plant ‘Blue Danube’ in sun to partial shade and moist, well-drained soil. It is best to remove the flowers when faded to encourage new buds. When the plant has completed blooming, it may be cut back to its basal foliage. In warmer climates, the leaves may be retained throughout the winter months. The plants may need to be divided about every three to four years. Divisions may be done in the spring and fall.
With its fluffy, pale lavender to bluish, cornflower-like blooms, ‘Blue Danube’ can be enjoyed in many different settings, including pollinator, butterfly, cottage, and rain gardens. Use it along a walkway or in borders, small groups, mass plantings, or containers.
Insects, Diseases, and Other Plant Problems: No significant problems.
