Growth Stages
| Stage | BBCH | Notes |
|---|---|---|
| Sowing | 0 | Sow seed densely at 5mm depth in full sun or part shade (RHS). |
| Thinning | 1 | Thin seedlings to 10cm (4in) apart as they emerge; keep well watered (RHS). |
| Leaf growth | 3 | Grows to around 20cm; sow successionally for a continuous leaf supply (RHS). |
| Cut-and-come-again harvest | 8 | Pick leaves over regularly, cut-and-come-again; unlike salad rocket it does not readily bolt (RHS). |

At a Glance
Harvest & Storage
When to pick: Pick leaves over regularly, cut-and-come-again, to keep plants from bolting and provide a continuous supply; unlike salad rocket, wild rocket is a perennial and does not bolt in the same way in warm weather. Yellow flowers are also edible and can garnish salads (RHS).

A perennial, Mediterranean leafy wild rocket to around 20cm in height, with a more peppery flavour than other varieties, smaller leaves and crunchy stalks. Yellow flowers are edible and can garnish salads. Native to Europe/Mediterranean, also native to GB/Ireland. Hardiness H3 (hardy in coastal and relatively mild UK parts, -5 to 1C). Full sun preferred, tolerates part shade. Soil: chalk, clay, loam or sand; moist but well-drained; acid, alkaline or neutral pH. Height/spread 0.1-0.5m. Time to maturity 1 year. Propagate by seed sown densely at 5mm depth; successive sowings give a continuous leaf supply; suitable for cut-and-come-again cropping. Pests: flea beetles, slugs, snails. Diseases: generally disease-free, though some cultivars such as 'Sele' offer mildew resistance -- implying mildew susceptibility exists in some cultivars.
