Threadleaf Tickseed

About this plant

Coreopsis verticillata 'Moonbeam' is a highly popular and reliable perennial, celebrated for its airy, fern-like foliage and an abundance of soft, lemon-yellow daisy-like flowers that bloom profusely from early summer through fall. Its compact, mounding habit makes it an excellent choice for borders, rock gardens, or mass plantings, providing continuous color and texture. 'Moonbeam' is particularly valued for its extended blooming period, virtually carefree nature, and ability to thrive in various conditions. This cultivar is a true garden workhorse, attracting beneficial pollinators while resisting deer, making it a fantastic addition to any landscape seeking long-lasting beauty with minimal effort.

Installation timing

When we're in season, outside of the winter months, our goal is to get your plants installed within about two weeks. That window gives us enough time to secure your plants from our supplier and find a spot on the schedule. Throughout the process we stay in touch through notifications and your existing client portal on the main A Cut Above website, which is separate from this landscaping plants shop.

Care & maintenance

Easily grown in average, well-draining soil. Deadhead spent flowers to encourage continuous blooming. Divide clumps every 2-3 years in spring to maintain vigor. Generally pest and disease free.

Watering suggestions

Proper watering is the single most important factor in your plant's survival after installation. Newly installed plants have a limited root system and rely on you for consistent moisture while they establish.

• First 2 weeks: Water deeply every day (or every other day in cooler, wet weather), soaking the root ball and surrounding soil.
• Weeks 3–12: Water deeply 2–3 times per week, adjusting for rain, heat, and soil drainage.
• After establishment: Water deeply about once a week during the growing season, and more often in extreme heat or drought.
• How to check: Stick a finger 2–3 inches into the soil near the roots — if it's dry, it's time to water. Deep, less-frequent watering encourages strong roots; shallow daily sprinkles do not.
• Avoid: Overwatering (soggy, waterlogged soil) is just as harmful as underwatering and can drown roots.

Watering needs vary by plant, season, soil, and exposure. Because proper watering is the customer's responsibility after installation, please make sure you understand and can follow these suggestions before ordering.

Good to know: plants and trees purchased from and installed by A Cut Above include a one-year limited warranty from the date of installation. Because plant survival depends heavily on proper watering and care after installation, losses caused by improper care, neglect, animal or chemical damage, or extreme weather are not covered, and we must be given the chance to inspect a struggling plant before it's removed or replaced. Coverage is one replacement per plant. Read our warranty info.
