    Easy to grow and flowering prolifically for several months in summer (especially if dead-headed regularly), these hard-working annuals make wonderful additions to the garden. The flowers are very pretty too, with soft pinkish-white petals that are irregularly edged in a rich shade of crimson. Grow more than you need so you have plenty for the vase.

  • Garden care:In early spring, sow shallowly in seed trays and keep under glass, transplanting them into individual pots when large enough to handle. Harden off before planting outside after the frosts. Alternatively, sow in-situ in mid to late spring in a well-prepared bed and thin the seedlings out as they grow to allow approximately 30cm between each. As the seedlings grow, pinch out the tips to encourage bushier plants. Taller plants may need supporting with brushwood stems in exposed positions.

  • Sow: March-May

  • Flowering: June-October
