Rob says: These beans, bred in France in the 1840s, form small bush-style plants. They are more cold hardy than most other varieties, so can be sown a few weeks earlier than others, & will crop for a few weeks later too. The beans are a waxy, yellow colour. Best picked young when they still have a flush of green on them, they have a fresh buttery flavour. As the beans are yellow & plants are short, they are easy to spot & easy to pick, ideal in containers or in front of taller crops. Try blanching a few & tossing them in your favourite salad for a bit of added crunch.
