Ivory Castle California Poppy Seeds – 50 Count

Southern Seeds was founded in 2019 by Ryan and Kim Dorn and became Seed Therapy in 2025. The family business moved its operations to the Dallas, Texas, area in 2023. Drawing on generations of growing experience, the team focuses on dependable seeds, personal customer service, and helping gardeners succeed. Its work includes relationships with American farms and seed donations to schools and community gardens.

These wildflowers are the same beautiful shape and form as the common California Poppy but bloom with a pleasant ivory blossom. A native cool-weather perennial flower, Ivory Castle California Poppy grows in open areas, hillsides, and along roadsides throughout the western United States. Upon maturity, this plant reaches a height of 12-16" with bluish green fern-like leaves and pale yellow cup-shaped flowers. In addition to attracting bees and butterflies, this plant is also resistant to deer, tolerates drought, is edible and medicinal, self-sows, and is great as a cut flower!

Planting Instructions:

Sow California poppy seeds in early spring, planting the seed 1/4" below the surface of the soil; keep the soil lightly moist until germination, which should occur in 2-3 weeks at a soil temperature of 60-65 degrees. In USDA Zones 7 and warmer, bulk poppy seeds can be fall planted. Poppies do not transplant well, and must be planted while very small if started indoors. Water seedlings occasionally, but decrease watering as the plants mature; poppies tolerate drought well and will only need watering in periods of extreme dryness. This plant tolerates most soils that drain well, as well as adapting to seaside conditions. This plant does not need rich soil, and actually blooms best in poor soil. Pinch off faded blossoms for the most prolific blooming.
