With a unique climbing habit Courgette 'Black Forest' makes a great space saving variety for growing in containers on the patio. The long stems will need tying onto a trellis or netting to gently train them upwards. Courgette Black Forest will produce heavy yields of dark green, smooth, cylindrical 15cm (6") courgettes if picked regularly throughout the summer. Height: 120cm (48"). Spread: 60cm (24").
