Charming, large spikes of single, lilac and purple flowers are produced in the spring filling the air with their sweet and spicy evening fragrance. Sweet Rocket will also attract butterflies and other beneficial insects to your garden. The hardy Biennial can be perennial in some soils.
Sow from May to June, transplant in autumn. Sow seed outdoors in a spare piece of ground or nursery bed. Prepare the ground well and rake to a fine tilth before sowing 12mm deep, in rows 30cm apart. Thin out plants to 15-30cm apart to get plants large enough for transplanting in autumn. Alternatively mix the seed with another annual wild flower and scatter thinly when sowing your wild flower border or meadow. Thin out as necessary. Plants will self-seed in following years after flowering. Space the plants 3cm apart in full sun or part shade. In the autumn, carefully lift plants and re-plant into final planting positions, spaced 3cm apart. Plant in any ordinary soil in full sun.
