Callirhoe Involucrata Seeds – 10 Purple Poppy Mallow Winecup Flower Seeds

Callirhoe involucrata, commonly known as purple poppy mallow or winecup, is a native perennial prized for its trailing stems and vivid magenta-purple, cup-shaped blooms. The flowers open in bright sunlight and close in the evening or on cloudy days, adding a cheerful, ever-changing element to sunny borders, rock gardens, and native plantings. Its low, spreading habit makes it an excellent groundcover for hot, dry sites and slopes.

Winecup is drought tolerant once established and attracts pollinators, making it a useful choice for water-wise landscapes, pollinator gardens, and wildflower meadows. The deeply lobed green foliage forms a dense mat that helps suppress weeds and soften the edges of paths or retaining walls.

Planting & Care

Sow Callirhoe involucrata seeds in a well-drained seed-starting mix. Lightly scarify the seed coat and soak seeds in water for several hours before sowing to help improve germination. Press seeds into the surface and cover lightly, as light may aid germination. Keep the medium consistently moist but not waterlogged, and provide warmth and bright light. Germination can be slow and uneven, so be patient.

Once seedlings are large enough to handle, transplant them into individual pots and grow them on before moving to the garden. Choose a sunny location with well-drained soil. Water regularly during the first growing season to help plants establish, then reduce watering as they become drought tolerant. Winecup generally needs little maintenance and can be left to spread naturally as a groundcover.
