Garden Cosmos 'Polidor'

Plant in a location that enjoys full sun and remember to water moderately. Keep in mind when planting that Polidor 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. Polidor requires a soil ph of 6.6 - 7.8 meaning it does best in weakly acidic soil - weakly alkaline soil.

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 Polidor about 28 days before your last frost date.

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

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