Rocket leaves are good in salads. Once you are used to the slightly peppery taste, you may find ordinary lettuce too bland.
It’s this taste which makes it resistant to slug attack. Rocket is easy to grow, and can be sown any time of year for a crop of fresh leaves. These contain the essential vitamin C not found in preserved foods.
If sown in autumn, the plant will overwinter as a small form, about 20cm (8 inches) high, with many leaves. These are densely packed, providing good ground cover so that little weeding is required.
You can use this as cut and come again for winter salads. Even if covered by snow, the plant can quickly regroup to produce more leaves. If it is protected from frost, you can browse on it all winter.
When spring arrives, though, it will grow quickly, with long tough stems. Flowers, as shown in the picture, appear. The energy of the plant will be directed to seeding, so the leaves will gradually become tatty from the attacks of small pests. All parts of the plant remain edible, though, and the flowers make a pretty decoration for summer salads.
The leaves become more fiddly to collect, so once the wild garlic is out and if you can use the space for more seasonal vegetables, dig up most of the rocket at this point. Leave the best looking plants to carry on flowering. They’ll produce seed, which you can harvest when the seed pods are dry. You can use this seed to sow your next crop of rocket.
It is a prolific self seeder as well, so learn to distinguish these seedlings from inedible weeds. If you allowed any rocket to go to seed this spring, the seedlings will be coming up right now. Sowing on a different patch with saved seed can be left until September.
