Sunflower 'double shine'

Try to plant in a location that enjoys full sun and remember to water often. double shine is generally regarded as a half hardy plant, so remember to protect this plant from frosts and low temperatures. double shine needs a loamy and clay soil with a ph of 5.7 to 8.1 (weakly acidic soil to weakly alkaline soil).

Try to aim for a seed spacing of at least 4.68 inches (12.0 cm) and sow at a depth of around 0.49 inches (1.25 cm). For optimal germination, soil temperature should be a minimum of 13°C / 55°F.

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

double shine 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
