Sweet rocket is most at home in an informal herbaceous border, or when left to naturalise in a wildlife-friendly garden. The deliciously scented, pale lilac flowers form in loose clusters and are attractive to bees and other beneficial insects. Their perfume will fill the air late spring and early summer evenings. They are also edible and look great sprinkled over salads. Although relatively short-lived, it self-seeds freely.

Our seedlings are grown individually in cell trays, and each plant measures about 4 - 6cm tall (from the base of the root to the top of the plant).

These seedlings are ideal for keen gardeners who have a greenhouse where the plants can be grown on until they are ready for planting out in the garden once all chance of frost has passed.

Please note: As we grow the seedlings especially for you, full payment is made when you place your order. See above for despatch dates. To ensure that your plants arrive in the best possible condition each pack will be despatched individually.


Garden care:
Pinch out the growing tips to encourage bushier growth and keep well watered. Feed with a good, high potash fertiliser (such as Tomorite) on a regular basis throughout summer. Dead-heading regularly will help prolong the flowering season, but if you want them to self-seed, allow some of the seed heads to develop fully.


  • Sowing instructions:
    Sow seed where it is to grow in late spring, after the worst of the frosts have passed. Prepare the bed well first and then surface sow, thinning the seedlings out as they grow to allow 30cm between each plant.


  • Sow: March to May
