The California poppy (Eschscholzia californica) is the state flower of California and a drought-adapted cool-season annual. Cup-shaped blooms in vivid orange, yellow, red, and pink open in morning sun and close at night. It thrives in poor, well-drained soils, self-sows freely, and goes dormant once summer heat arrives. Ideal for naturalized wildflower meadows and xeriscaping projects.
Eschscholzia californica · Flower · Papaveraceae family · 60–90 days to maturity

Growing Tips for California Poppy
Direct-sow only — the taproot cannot survive transplanting. In zones 6–7, scatter seeds in early spring as soon as soil is workable; seedlings tolerate light frost. In zones 8–10, fall-sow Oct–Dec for winter/early spring bloom. Simply scatter on bare, cultivated soil and press gently — seeds need light and soil contact but minimal cover. Thin to 6 inches. Avoid fertilizing; rich soil encourages foliage over flowers. Allow seed heads to mature and shatter for naturalized self-sowing colonies year after year.
