Overview

In the Garden
'Blue Danube' reaches a mature diameter of 12 inches (30.5 cm) and a height of 7 inches (17.8 cm), making it suitable for the front of borders, rock gardens, or as a groundcover in partial to full shade.

Care Notes
Provide consistent moisture, especially during dry periods, and apply a balanced fertilizer in early spring as new growth emerges. Standard precautions against slugs and deer are recommended, as both can damage the foliage.
