The perfect dual-purpose vegetable as it produces an abundant harvest of pencil-thin, stringless green beans with a fine, sweet flavour from early summer. Later in the season, the last few pods can be left on the plant to dry as white haricot beans for storage.
An heirloom climbing cultivar from 1885, 'Blue Lake' makes making a decorative addition to any garden when grown up a trellis or wigwam.
Growing instructions:
Sow three seeds to a 15cm pot in mid-April and keep well watered and warm until germination. Keep seedlings in a frost-free greenhouse or on a windowsill, potting them on as they grow, and once all threat of frost has passed harden off gradually before planting out. Protect young plants from slugs and support with hazel wigwams or trellis. If you sow a second batch of French beans in July it will provide a continuous harvest well into autumn.
