Sunflower 'Topolino'

A full sun position will ensure your plant thrives and remember to water often. Keep in mind when planting that Topolino is thought of as half hardy, so protect with a row cover whenever the temperatures drop. Topolino requires a loamy and clay soil with a ph of 5.7 - 8.1 - it grows 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 Topolino about 21 days before your last frost date.

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

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