Sunflower 'Evening Sun'

Sow seeds outdoors after last frost. Sunflowers prefer full sun to light shade and well-drained rich soil. Some plants may need some support.

A full sun position will ensure your plant thrives and remember to water often. Keep in mind when planting that Evening Sun is thought of as half hardy, so remember to protect this plant from frosts and low temperatures. Planting Evening Sun in loamy and clay soil with a ph of between 5.7 and 8.1 is ideal for as it does best in 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). Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

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

As Evening Sun is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.

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