Sunflower 'Skyscraper'

Try to plant in a location that enjoys full sun and remember to water often. Keep in mind when planting that Skyscraper is thought of as half hardy, so it will need cloching or fleece protection when the temperature dips. Ensure your soil is loamy and clay and has a ph of between 5.7 and 8.1 as Sunflower is a weakly acidic soil to weakly alkaline soil loving plant.

Look to ensure a distance 4.68 inches (12.0 cm) between seeds when sowing - bury at a depth of at least 0.49 inches (1.25 cm) deep. Soil temperature should be kept higher than 13°C / 55°F to ensure good germination.

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

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

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