Garden Cosmos 'Sunset'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Sunset is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside. Ensure your soil has a ph of between 6.6 and 7.8 as Sunset is a weakly acidic soil - weakly alkaline soil loving plant.

Try to aim for a seed spacing of at least 0.98 inches (2.5 cm) and sow at a depth of around 0.25 inches (0.64 cm). Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.

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

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

The botanical epithet is from the Latin bipinnatus meaning “staunch” or “like two small wings”.²

Salt Spring Seeds says that this is a heritage variety which was introduced in the 1890s. ¹
