Celandine Poppy

About this plant

Stylophorum diphyllum, commonly known as Celandine Poppy, is a captivating woodland perennial celebrated for its brilliant, cup-shaped yellow flowers. Emerging in early to mid-spring, these cheerful blossoms provide a welcome splash of color, often before many other shade plants awaken. Its deeply lobed, attractive foliage adds textural interest throughout the growing season. Beyond its early season charm, the Celandine Poppy is a low-maintenance plant, ideal for naturalistic plantings, shade gardens, or woodland edges. It readily self-seeds in favorable conditions, forming charming colonies that further enhance its woodland appeal. A true spring ephemeral, the foliage may die back in the heat of summer, especially in drier conditions, allowing other shade-loving plants to take center stage. This native beauty is perfect for adding a touch of golden sunshine to dappled shade areas, creating a vibrant focal point or a cheerful carpet beneath established trees and shrubs. Its unique seed pods also provide interesting visual texture later in the season.

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

Celandine Poppy is relatively easy to grow. Plant in well-drained, organically rich soil. Provide consistent moisture, especially during dry spells, particularly in its establishment phase. Spent flowers can be left to allow for self-seeding, or deadheaded if fewer volunteers are desired. No serious pest or disease issues. Mulch lightly in fall to protect roots and enrich soil.

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.
