Sunflower 'Choco Sun'

Try to plant in a location that enjoys full sun and remember to water often. Choco Sun is generally regarded as a half hardy plant, so it will need protecting in periods of cold weather. Choco Sun needs a loamy and clay soil with a ph of 5.7 to 8.1 (weakly acidic soil to weakly alkaline soil).

Aim to sow 0.49 inches (1.25 cm) deep and try to ensure a gap of at least 4.68 inches (12.0 cm). For optimal germination, soil temperature should be a minimum of 13°C / 55°F.

By our calculations, you should look at sowing Choco Sun about 21 days before your last frost date.

Choco Sun is half hardy, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

The botanical epithet is from the Latin annuus meaning “annual”.¹
