European michaelmas daisy, also known as Summer michaelmas daisy

A perennial harboring vibrant, daisy-like flowers, european michaelmas daisy thrives with post-bloom deadheading to encourage further flowering and maintain vigor. Key pruning involves cutting back spent stems to basal foliage after flowering, typically in fall, and lightly trimming the plant in spring to promote dense growth. Prune sparingly mid-season to remove wilted flowers. This maintenance prevents self-seeding, which can result in loss of hybrid vigor, and contributes to a more prolific bloom the following season.
