  • Position: full sun
  • Soil: well-drained, preferably poor soil
  • Rate of growth: average
  • Flowering period: May to July
  • Flower colour: deep brownish red
  • Other features: the flowers are attractive to butterflies and bees
  • Hardiness: hardy annual

    Altogether charming, dark crimson flowers, which look almost black on cloudy days, sit on top of upright, branching stems, looking like miniature pom-poms. Ideally suited to wildflower meadows or naturalised planting schemes, the flowers will hold their colour well and will attract beneficial insects in their droves.

  • Garden care:In early autumn surface-sow in trays of good seed compost and over-winter in a cold frame or greenhouse, thinning out and potting on as they grow. These can be planted out in spring and produce early flowers. Alternatively, shallow-sow directly into a well-prepared seedbed in spring, thinning out to 15cm. This plant will produce more flowers when grown in poor soils, so don’t over-fertilise. Pinching out the growing tips will encourage bushier growth.

  • Sow: September-October or March-April

  • Flowering: May-July

  • Approximate quantity: 300 seeds.
