Common yarrow 'Rosie'

Try to plant in a location that enjoys full sun and remember to apply water fairly sparingly. Keep in mind when planting that Rosie 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 Rosie about 49 days before your last frost date.

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