Garden Cosmos 'Sonata white'

Try to plant in a location that enjoys full sun and remember to water moderately. Sonata white is generally regarded as a tender plant, so remember to ensure that temperatures are mild before moving outdoors. Sonata white needs a soil ph of 6.6 to 7.8 (weakly acidic soil - weakly alkaline soil).

Light aids germination which will occur in 7 to 15 days.²

Aim to sow 0.25 inches (0.64 cm) deep and try to ensure a gap of at least 0.98 inches (2.5 cm). For optimal germination, soil temperature should be a minimum of 20°C / 68°F.

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

Sonata white is tender, so ensure you wait until all danger of frost has passed in your area before considering planting outside.

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