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.

California Poppy Heat Requirements (GDD)

What are Growing Degree Days (GDD)?

Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.

Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

California Poppy needs ~1,538 GDD — county provides 4,694 GDD Excellent fit

Growing Tips for California Poppy in Lee County

Direct sow California Poppy outdoors after March 23 in Lee County when soil has warmed and frost danger has passed.

With Lee County's clay soil (32% clay), work in 3-4 inches of compost before planting California Poppy. Avoid tilling when soil is wet to prevent compaction.

General growing tips

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.
