More About Coreopsis ‘Moonbeam’

Coreopsis ‘Moonbeam’ is one of the most beloved and widely planted tickseed varieties—and for good reason. Its soft, pale lemon-yellow flowers have a light, airy quality that brightens the garden without overpowering neighboring plants. The blooms appear in incredible abundance, floating just above fine, threadlike foliage that gives the plant a graceful, almost ferny texture.

Flowering begins in late spring and continues steadily through summer and often well into early fall. Unlike many perennials that bloom in short bursts, ‘Moonbeam’ delivers consistent color for months. Even when not in bloom, the foliage remains attractive, forming a tidy mound that blends effortlessly into mixed borders and naturalistic plantings.

Why We Like It (Our Trials)

In our trials, ‘Moonbeam’ has proven to be one of the most reliable long-blooming perennials available. It handles heat, humidity, and periods of drought with ease, all while maintaining a soft, refined appearance. Once established, it requires very little care beyond occasional trimming to refresh the plant.

We especially value how versatile it is. ‘Moonbeam’ looks just as good massed along a border as it does woven through a pollinator or cottage garden. Pollinators visit it constantly, yet deer almost always leave it alone. It’s a classic, no-fail perennial that performs year after year with minimal effort.

Coreopsis ‘Moonbeam’ vs. Other Coreopsis Varieties

Compared to large-flowered coreopsis like ‘Early Sunrise’ or ‘Double the Sun,’ ‘Moonbeam’ offers a more delicate look with smaller flowers and much finer foliage. While the blooms are subtler, the sheer number of flowers and the extended bloom season often surpass those of larger-flowered types.

When compared to other threadleaf coreopsis, ‘Moonbeam’ stands out for its softer flower color and exceptional longevity in the landscape. It spreads slowly without becoming aggressive and maintains a graceful, mound-forming habit. For gardeners seeking a long-blooming, low-maintenance perennial with elegant texture and dependable performance, Coreopsis ‘Moonbeam’ remains one of the very best choices.
