Growing Sunflower in Anaheim
Anaheim's Zone 10b inland Southern California climate is warm and dry year-round with virtually no frost risk. The slightly hotter, drier conditions compared to coastal Orange County are excellent for warm-season crops like tomatoes, peppers, and eggplant during the long spring and fall windows. Cool-season vegetables thrive throughout the mild winter months from November through March.
In Anaheim, sunflower can be planted in late winter or early spring — typically February or March — before summer heat peaks.
Sunflower thrives between 60°F and 95°F. It is frost-sensitive, meaning a single freeze at 32°F will damage or kill it — always wait until frost danger has fully passed. Expect 70–100 days from transplant to first harvest. Direct sow preferred. Full sun and well-drained soil.
