More About Leucanthemum ‘Flower Power’

‘Flower Power’ delivers big, bold, classic Shasta Daisy blooms with clean white petals and sunny yellow centers that immediately brighten the garden. The flowers are held upright on sturdy stems, creating a cheerful display that feels both timeless and familiar. I have always appreciated how certain daisies capture that classic garden look without feeling outdated, and ‘Flower Power’ does exactly that. The blooms have a strong presence, rising clearly above the foliage where they can be seen easily across the border. When several plants are grouped together, the effect is a vibrant field of white flowers that catches the light beautifully. It has that welcoming, happy character that makes people stop and smile when they walk by. In many ways it represents the very image people have in mind when they think of a Shasta Daisy.

Another reason this variety stands out is its balanced growth habit and dependable performance. The plants grow with a uniform shape that feels neat and intentional rather than loose or sprawling. Each stem holds its flower upright, allowing the blooms to stay visible and clean even as the plant fills out. Flowering typically begins in Early Summer and continues steadily with simple deadheading. I appreciate plants that reward just a little attention with a longer bloom period, and this one certainly does. The foliage forms a healthy mound beneath the flowers that supports the overall structure of the plant. Because of that tidy habit and reliable flowering, it is an easy choice for gardeners who want strong performance without constant maintenance.

Why We Like It (Our Trials)

In our trials here at Garden Delivery, ‘Flower Power’ has proven to be consistent, durable, and very dependable in real garden conditions. The plants have handled Summer wind and rain with surprising strength, with stems that remain upright even when storms move through. That kind of resilience is important because many older Shasta Daisy varieties would start leaning or collapsing once the flowers became heavy. With ‘Flower Power’ the blooms stay clean and visible, keeping the display looking fresh for longer. When deadheaded regularly, the plant continues producing new flowers throughout the season. I also appreciate how the plant forms a full, balanced clump that looks deliberate and well placed in the landscape. It never feels wild or floppy, which makes it easy to design with.

We also value how versatile this variety is in different parts of the garden. It works beautifully in perennial borders where the white flowers create contrast against colorful companion plants. At the same time it blends naturally into cottage style gardens where daisies feel right at home among other classic perennials. The flowers are also excellent for cutting, producing strong stems that hold up well in bouquets. When we bring them indoors they tend to last a long time in a vase, which customers always appreciate. Another bonus is the steady stream of pollinators that visit the blooms throughout the flowering period. Bees and butterflies seem to find the flowers quickly and return again and again as the plant continues blooming.

Flower Power vs. Other Shasta Daisies

‘Flower Power’ earns its name through sheer bloom production, often outpacing the others in flower count and seasonal impact. Compared to Amazing Daisies® Marshmallow, the blooms are slightly smaller but appear in greater numbers, creating a more energetic, high-contrast display. Instead of producing a few oversized flowers, it spreads its energy across many stems, which helps the plant look full and vibrant for a longer portion of the season.

It has a bolder presence than both Sweet Daisy® Izabel and Sweet Daisy® Jane especially in mass plantings where consistency and volume matter most. While REALFLOR® Real Sunbeam offers unique coloration, ‘Flower Power’ wins for gardeners seeking nonstop white blooms with classic yellow centers and strong visual rhythm. For gardeners who want a dependable daisy that delivers consistent color and energy throughout Summer, this variety is hard to beat.
