California poppy grows as a mound of ferny, finely dissected, gray-green foliage, topped from early spring to mid summer with many slender, upright flower stems. The simple, cup-shaped flowers have satiny petals in shades of orange; there are also many cultivars available that expand the color range with reds, pinks, yellow and creamy white, and semi-double to double flower forms. Not surprisingly, California poppy is quite drought-tolerant. It’s an excellent choice for garden spots with dry, sandy soil, and it also thrives in nutrient-poor conditions.

Pests and diseases
- Prone to foliar and root fungal diseases in very humid climates or overly wet soils.
- ‘Mission Bells’ has double and semi-double flowers in a range of colors (white, orange, pink, yellow).
- ‘Rose Chiffon Thai Silk’ has silky rose-pink double flowers.
- ‘Buttercream’ has creamy palest yellow flowers.
- ‘Tropical Sunset’ is a mix of single and semi-double flowers in shades of red, orange, pink, yellow and cream.
- California poppy is a cool-season bloomer. In warm climates, sow seeds in fall for late winter to spring bloom; in colder regions, sow in spring as soon as the soil can be worked.
- California poppy foliage often dies back in late summer, but new foliage returns in cooler autumn conditions.
- It’s a prolific re-seeder—this can be a welcome quality in difficult sites, but if seedlings spread out of bounds they’re easy enough to pull or hoe.
