Moonbeam Coreopsis

The Coreopsis verticillata 'Moonbeam' is valued for its long-lasting, creamy yellow flowers and fine, delicate foliage. This perennial grows to a height and width of 1.5 to 2 feet, forming mounded clumps that thrive in full sun. It performs well in USDA Zones 3 to 9, where it enjoys dry to medium, well-drained soils. The showy, daisy-like flowers appear singly in loose clusters, creating a bright, cheerful display that lasts from late spring through summer, with the potential for a fall rebloom if sheared in mid-summer.

The finely textured foliage is palmately divided, giving the plant a light, airy appearance. Threadleaf Coreopsis tolerates deer, drought, and poor soils, making it a reliable performer in challenging garden conditions.

Threadleaf Coreopsis adds long-lasting color and texture to a variety of garden settings. Here are some common uses:

• Borders: Use Moonbeam coreopsis in sunny borders for its vibrant flowers and fine-textured foliage, which provide continuous interest throughout the growing season.
• Naturalized Areas: Plant in naturalized or meadow-style plantings where its tolerance to drought and poor soils allows it to thrive with minimal care.
• Cottage Gardens: Its delicate, airy form and cheerful flowers make it an ideal addition to cottage-style gardens.
• Rock Gardens: This plant performs well in dry, well-drained soils, making it a perfect choice for rock gardens.
• Pollinator Gardens: Attracts butterflies and other pollinators, providing ecological value to the landscape.

Threadleaf Coreopsis is an easy-to-grow perennial that requires minimal care once established. Follow these care tips for optimal growth:

• Planting Location: Choose a spot with full sun for the best flowering performance. Moonbeam thrives in well-drained soils and is particularly suited for dry or rocky areas. Avoid planting in overly moist or fertile soils, which can cause the plant to sprawl.
• Watering: Water regularly during the first growing season to establish deep roots. Once established, Moonbeam is highly drought-tolerant and only requires occasional watering during prolonged dry spells.
• Pruning: Deadhead spent flowers regularly to encourage additional blooming and prevent self-seeding. Shearing the plant back in mid-summer will promote a second bloom in fall and keep the foliage neat and tidy.
• Dividing: Divide the clumps every 2-3 years in spring or fall to maintain plant vigor and prevent overcrowding.
• Fertilizing: Avoid over-fertilizing, as rich soils can lead to sprawling growth. A light application of compost in spring is usually sufficient.
