Sunflower 'Paul Bunyan'

Paul Bunyan likes a position of full sun and remember to water often. Keep in mind when planting that Paul Bunyan is thought of as half hardy, so it will need protecting in periods of cold weather. Ideally plant in loamy and clay soil and try to keep the ph of your soil between the range of 5.7 and 8.1 as Paul Bunyan likes to be in 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). Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

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

Ensure that temperatures are mild and all chance of frost has passed before planting out, as Paul Bunyan is a half hardy plant.

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