More About Leucanthemum ‘Amazing Daisies® Marshmallow’

Leucanthemum ‘Amazing Daisies® Marshmallow’ is prized for its fully double, fluffy white blooms that resemble soft marshmallows perched atop sturdy stems. The flowers are larger and more substantial than traditional Shasta daisies, creating a lush, full appearance while still maintaining a classic garden feel.

Unlike older double daisies that can flop or bloom briefly, this variety was bred for improved stem strength and extended flowering, delivering a long season of clean, upright blooms.

Why We Like It (Our Trials)

In our trials, ‘Amazing Daisies® Marshmallow’ has shown excellent garden performance, holding its flowers upright even after rain and wind. It reblooms reliably through summer with simple deadheading and maintains a tidy clump without excessive spreading.

We especially appreciate its versatility. It works beautifully as a focal point in perennial borders, blends naturally into cottage-style gardens, and produces outstanding cut flowers with long vase life.

Amazing Daisies® Marshmallow vs. Other Shasta Daisies

Amazing Daisies® Marshmallow stands apart from other Shasta Daisies with its extra-large, soft white blooms and refined, high-end appearance. Compared to Leucanthemum Flower Power and REALFLOR® Real Sunbeam, Marshmallow leans more ornamental and less bold, prioritizing elegance over color saturation or sheer flower volume. It offers fuller blooms than both Sweet Daisy® Izabel and Sweet Daisy® Jane making it an excellent choice when you want a premium, statement daisy rather than a classic meadow look. Marshmallow keeps flowers upright and clean, giving it a more polished presence than many traditional Shasta daisies.
