Self-seeds gently to form naturalized colonies without aggressive spreading.

Blooming from April into June, the four-petaled flowers open in loose clusters above a rosette of bold, deeply lobed foliage that carries its own ornamental weight long after the last petal drops.\u003c\/p\u003e\n\u003cp\u003eThe leaves are a striking blue-green with silvery, softly hairy undersides, creating a texture that pairs beautifully with the broad leaves of hostas, the delicate fronds of maidenhair fern, and the vertical spikes of foamflower. In consistently moist soil, the foliage holds well into fall. In drier conditions, plants may go dormant by midsummer and return with renewed vigor the following spring.\u003c\/p\u003e\n\u003cp\u003eCelandine Poppy self-seeds at a manageable pace, gradually filling shaded areas with a naturalized carpet of color and foliage. Unwanted seedlings pull easily if the colony outgrows its welcome. The stems and leaves contain a yellow-orange sap that is toxic to mammals, making this one of the more reliably deer-resistant native perennials for shade gardens throughout its range in eastern North America.\u003c\/p\u003e\n\u003ch2\u003eCare\u003c\/h2\u003e\n\u003ch3\u003e\u003cstrong\u003eCelandine Poppy Care\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003ePlant Celandine Poppy in partial to full shade. It performs best in the dappled light beneath deciduous trees where it receives spring sun before the canopy fills in. Rich, moist, humus-heavy soil produces the best foliage persistence and longest bloom period. The plant tolerates a range of soil pH including both acidic and slightly alkaline conditions.\u003c\/p\u003e\n\u003cp\u003eWater consistently during the first growing season and maintain even moisture through summer if you want foliage to persist into fall. Established plants tolerate short dry spells but will go dormant early if drought is prolonged. This dormancy is not harmful — the plant returns reliably the following spring.\u003c\/p\u003e\n\u003cp\u003eFertilization is generally unnecessary in rich woodland soils. In leaner conditions, a light application of \u003ca href=\"https:\/\/almanacplanting.com\/products\/slow-release-fertilizer\" target=\"_blank\" rel=\"noopener\"\u003eslow release fertilizer\u003c\/a\u003e in early spring is sufficient. Deadhead spent flowers to extend the bloom period and reduce self-seeding if desired. Cut back yellowing foliage in midsummer to tidy the planting — it will not harm the plant.\u003c\/p\u003e\n\u003ch2\u003eSize\u003c\/h2\u003e\n\u003ch3\u003e\u003cstrong\u003eWhat Size is the Celandine Poppy for Sale Online?\u003c\/strong\u003e\u003c\/h3\u003e\n\u003cp\u003eOur Celandine Poppy ships in a greenhouse-grade grow pot and is appropriately sized for its container at the time of shipment.

Seedlings are shallow-rooted and easy to pull if they appear where they are not wanted.
