Broccoli : Belstar F1 Hybrid

Broccoli 'Belstar' F1 Hybrid (Calabrese)

Brassica oleracea (Italica Group)
 Customer Rating

The well domed, small beaded heads of Broccoli ‘Belstar’ have an excellent flavour, and a healthy green colour. The firm heads of this RHS AGM variety remain in good condition for a long time, producing plenty of side shoots once the central head is cut. This tasty variety can be planted in succession for an ongoing harvest from late summer to autumn. Height: 45cm (18”). Spread: 40cm (16”).


Andrew Tokely says: "I always sow this broccoli early in the year and harvest large tasty heads before they can be attacked by caterpillars. Once the main head is cut, I give the plants a good watering, so over the following weeks and months a secondary crop of tasty smaller spears are produced making this a very worthwhile crop."


Companion planting: Try growing broccoli with Nasturtiums to draw cabbage white butterflies away from your crop, and mint to help deter flea beetles.
