Purple beans you can see from the other end of the garden. Blauhilde is a classic German runner bean variety with dark purple, fleshy pods measuring 20–25 cm in length. They contrast beautifully with the dark green leaves and purple flowers. The plants climb to 3–4 m, covering poles and fences, and the pods turn dark green when cooked – something children love to watch.

What makes this variety special
Blauhilde is one of the best-known purple beans in the world – a late, exceptionally productive and highly ornamental variety. The pods are thick and fleshy, remaining stringless even when slightly overgrown, and their sweet flavour is more pronounced than that of green varieties. The purple pigment (anthocyanins) disappears during cooking, so the beans are green on the plate – but their intense colour makes the pods especially easy to find among the leaves when harvesting.
As a climbing variety, Blauhilde produces a long, staggered harvest until the first frosts, so a few plants can provide beans throughout the entire late season. It also tolerates somewhat cooler summers, which is not something that can be taken for granted with beans.
Growing step by step
Sowing (first half of May, outdoors): after the last frosts have passed, when the soil temperature is at least 10–12°C. Sow 3–4 seeds per planting station, 3–4 cm deep, at 50–60 × 50–60 cm spacing, with supports already in place. Germination takes 8–14 days.
Thinning: usually unnecessary – all seedlings from one planting station can grow together on a single pole. If more than 4 emerge, remove the weaker ones.
Supports: 2–2.5 m poles, a bamboo wigwam, netting or a tall fence. Wrap young shoots around the support anticlockwise – they will then manage on their own.
Care: water during dry periods, especially during flowering; mulching helps retain moisture and protects the shallow roots. Beans fix nitrogen themselves, so nitrogen fertilisation is unnecessary. Harvest the pods regularly every few days – this encourages the plant to set new ones.
Uses
Blauhilde is versatile in the kitchen: steamed, in salads, with breadcrumbs or as an accompaniment to meat. Young pods can be eaten raw, while any excess can be frozen or made into pickles and jarred salads. It is also one of the most attractive edible plants: a pergola, fence or pole teepee covered with it becomes a garden ornament and a natural screen from neighbours. It also grows very well in a large container on a terrace with support.
Gardener’s tip
Do not sow beans too early: in cold, wet soil the seeds may rot, while seedlings that do emerge will still lag behind those sown a week later in warm soil. The purple colour of the pods is a bonus at harvest – you can see every pod, making it harder to miss those that would become overgrown and reduce further production.
