About this plant

'Blue Moon' Phlox is a true gem for the shade garden, gracing your landscape with a profusion of delicate, lavender-blue flowers in early to mid-spring. These charming blooms, held atop airy stems, release a sweet, subtle fragrance that invites both admiration and early pollinators. This native perennial forms a lovely mat of semi-evergreen foliage, creating a soft, green carpet that remains attractive even when not in bloom. Perfect for naturalizing in woodland settings, under deciduous trees, or along shaded borders, 'Blue Moon' provides a serene and vibrant display that announces the arrival of warmer weather. At A Cut Above, we select only the finest specimens to ensure vigorous growth and abundant flowering. Plant 'Blue Moon' Phlox for an effortless touch of woodland elegance and a reliable spring spectacle that returns year after year.

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

Requires well-drained, organically rich soil. Mulch annually to retain moisture and keep roots cool. Water regularly during dry periods, especially in its first year. Deadheading spent blooms is not necessary but can tidy the plant. Divide crowded clumps every 3-4 years in early spring or fall to maintain vigor.

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.
