'Blauhilde' Pole Bean – traditional violet climbing bean with long, tender, stringless pods that turn green when cooked.
Annual, warmth‑loving legume with long, violet, stringless beans and an aromatic, mildly flavoured taste. The plants grow vigorously climbing, reach 250–300 cm in height and require a support structure. They thrive reliably in sunny, warm locations in open ground, raised beds or the garden, with moderate water needs and strong yield reliability. The variety is robust, low‑maintenance and open‑pollinated – ideal for self‑sufficiency, companion planting and ecological cultivation.
Origin & History
‘Blauhilde’ is a traditional European pole bean that has been grown in home gardens since the mid‑20th century. It belongs to the classic climbing Phaseolus vulgaris types, valued for their exceptionally long, violet, stringless pods. As an open‑pollinated variety, it has been stabilised over decades through gardener selection and adapted to a wide range of garden soils. Botanically, it belongs to the family Fabaceae, subfamily Faboideae, genus Phaseolus.
The first documented mention of the variety dates to 1964, when it was described in the German horticultural reference “Das Lexikon der alten Gemüsesorten” as a new violet pole bean with stringless pods and high yield reliability. As a colour‑intense post‑war bean, it spread rapidly through Central European kitchen gardens during the 1960s and 1970s and became established in European gardening publications. Since then, it has been regarded as a robust, colour‑stable and productive variety with exceptionally long pods for home and farm gardens.
Its violet colour was considered a special feature that attracted attention both in cultivation and in the kitchen. Particularly characteristic is the so‑called “magic bean effect”: the deep‑violet pods turn a bright emerald green when cooked – a colour change that made it a beloved children’s and family bean in many households. The variety proved especially reliable in regions with changeable summers, as it flowers consistently, offers long harvest periods and produces stable yields even under less‑than‑ideal conditions. In smallholder and self‑sufficiency gardens, it is still valued today for its long, stringless pods, mild‑aromatic flavour and high resilience, and remains one of Europe’s most popular violet pole beans.
Appearance & Characteristics
‘Blauhilde’ is annual, herbaceous and strongly climbing. It forms long, twining shoots with medium‑green foliage. The white to slightly violet‑tinged flowers appear from early summer. After flowering, long, round, violet, stringless pods develop, containing tender, cream‑coloured seeds. The root system is tap‑rooted with strong lateral roots. Annual in cultivation, not winter‑hardy.

Usage & Cultivation Highlights
‘Blauhilde’ is excellent for pan dishes, vegetable sides, stews, wok dishes, tempura, pickling, fermenting and long‑term storage. The stringless pods can be steamed, boiled, fried, grilled, deep‑fried or frozen after blanching, while keeping a pleasant bite. Their mild, delicate aroma makes them versatile – from traditional home cooking to modern vegetable cuisine. Young pods pair well with herbs such as summer savoury, tarragon or lemon thyme and fit perfectly into bowls, pasta dishes, summer vegetable pans and light curries. ‘Blauhilde’ also works beautifully in oven dishes, hearty gratins, stuffed vegetables, rice and grain pans, warm mezze, vegetable antipasti, fine vegetable creams, bean pesto, marinated grilled vegetables, summer salads, vegetable chips and aromatic soup garnishes. In cold dishes, the pods enrich pickles, appetiser platters, bowl toppings and light lunch dishes. Mature seeds can be dried and used as dry beans.
In cultivation, ‘Blauhilde’ is highly reliable: it prefers sunny, warm locations and performs well even in regions with changeable summers. Thanks to its vigorous growth, it needs a stable climbing support, yet remains low‑maintenance and largely disease‑resistant. Even moisture promotes pod set, while waterlogging should be avoided. The plants thrive reliably even in less‑than‑ideal soils. As a legume, it fixes nitrogen and improves long‑term soil fertility. Its long growing season allows for an extended harvest over many weeks. ‘Blauhilde’ also impresses with strong heat tolerance, robust standability and the ability to bridge dry periods thanks to its deep taproot. The variety shows strong competitiveness against weeds, steady flowering into late summer and remarkable uniformity in pod formation. In companion planting – especially with cabbage, lettuce, maize or herbs – it remains vigorous and productive.
Compared to other pole beans, ‘Blauhilde’ stands out with its exceptionally long, violet, stringless pods, mild flavour and high yield reliability – ideal for self‑sufficiency, family gardens, mixed cropping and ecological cultivation.
