Garden Cosmos 'Sonata'

Sonata likes a position of full sun and remember to water moderately. Keep in mind when planting that Sonata is thought of as half hardy, so it will need cloching or fleece protection when the temperature dips. Ensure your soil has a ph of between 6.0 and 8.5 as Sonata is a weakly acidic soil - weakly alkaline soil loving plant.

Look to ensure a distance 5.85 inches (15.0 cm) between seeds when sowing - bury at a depth of at least 0.0 inches (0.0 cm) deep. Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.

By our calculations, you should look at sowing Sonata about 28 days before your last frost date.

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

The botanical epithet is from the Latin bipinnatus meaning “staunch” or “like two small wings”.¹
