Overview of Dragon Tongue Beans
Dragon tongue beans, scientifically known as Phaseolus vulgaris, are an heirloom variety of bush beans. Originally from the Netherlands, they’re also called Dutch heirloom, Merveille de Piemonte, or Dragon Langerie beans.
These beans stand out due to their striking appearance. The pods feature vibrant purple streaks on a creamy yellow background, creating a visually appealing pattern reminiscent of a dragon’s tongue.
Dragon tongue beans typically grow to 4-6 inches long. They have a flat, broad shape and a crisp texture when fresh. As they mature, the purple streaks fade to a more uniform yellow color.

Cultivation Tips
Dragon tongue beans thrive with proper planting and care. Attention to soil, sunlight, and maintenance ensures a bountiful harvest of these unique bush beans.
Planting Requirements
Plant dragon tongue bean seeds in full sun after the last frost. Choose a spot with well-drained soil rich in organic matter. Space seeds 6 inches apart in rows 18 inches apart. Sow seeds 1 inch deep.
These bush beans prefer slightly acidic soil with a pH of 6.0-6.5. Add compost to improve soil structure and fertility. Avoid excessive nitrogen, as it promotes leafy growth at the expense of bean production.
Dragon tongue beans germinate quickly and grow vigorously. They adapt well to container gardening if adequate drainage is provided.
Maintenance and Care
Water dragon tongue beans consistently, keeping the soil moist but not waterlogged. Mulch around plants to retain moisture and suppress weeds. Avoid overhead watering to prevent fungal diseases.
Monitor for pests, especially Mexican bean beetles. Use row covers or handpick beetles to protect plants. Rotate crops annually to reduce disease risk.
Harvest dragon tongue beans when pods are 4-6 inches long, typically 50-60 days after planting. Pick frequently to encourage continued production. Beans are ready when pods snap easily and seeds are still small.
For dried beans, leave pods on plants until they turn brown and brittle. Harvest before frost and complete drying indoors if necessary.
Cooking and Preparation
Dragon tongue beans offer versatile culinary options with their unique flavor and texture. They can be prepared using various cooking techniques and paired with complementary ingredients to create delicious dishes.
Cooking Techniques
Dragon tongue beans can be cooked using several methods. Boiling is a simple technique – add the beans to salted boiling water for 3-5 minutes until tender-crisp. Steaming preserves nutrients and color, taking about 5-7 minutes.
Sautéing brings out the beans’ sweet flavor. Heat olive oil in a pan, add the beans, and cook for 3-4 minutes while stirring. Roasting intensifies their taste – toss with oil and roast at 400°F for 10-12 minutes.
For raw preparations, thinly slice the beans and add to salads for a crisp texture. Blanching briefly in boiling water then shocking in ice water maintains crispness while softening slightly.
Flavor Pairings
Dragon tongue beans have a mild, sweet flavor that pairs well with various ingredients. Garlic and lemon juice enhance their natural taste. Sauté with minced garlic and finish with a squeeze of lemon for a simple side dish.
Cherry tomatoes complement the beans’ sweetness. Toss blanched beans with halved cherry tomatoes, olive oil, and fresh herbs. Nuts like almonds or pine nuts add crunch and richness to bean salads or sautés.
Herbs such as basil, thyme, or dill bring freshness. Toss steamed beans with chopped herbs and butter. For Asian-inspired flavors, stir-fry with ginger, soy sauce, and sesame oil.
