Common yarrow 'Cassis'

Plant in a location that enjoys full sun and remember to apply water fairly sparingly. Keep in mind when planting that Cassis is thought of as hardy, so this plant will survive close to or on freezing temperatures.

Try to aim for a seed spacing of at least 11.9 inches (30.5 cm) and sow at a depth of around 0.25 inches (0.635 cm). Soil temperature should be kept higher than 18°C / 64°F to ensure good germination.

By our calculations, you should look at sowing Cassis about 49 days before your last frost date.

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