Garden Cosmos 'Psyche Mix'

Try to plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Psyche Mix is thought of as half hardy, so remember to protect this plant from frosts and low temperatures. A soil ph of between 6.0 and 8.5 is ideal for Psyche Mix as it does best in weakly acidic soil - weakly alkaline soil.

Try to aim for a seed spacing of at least 5.85 inches (15.0 cm) and sow at a depth of around 0.0 inches (0.0 cm). Soil temperature should be kept higher than 20°C / 68°F to ensure good germination.

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

As Psyche Mix is half hardy, ensure temperatures are mild enough to plant out - wait until after your last frost date to be on the safe side.

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