The Botanical Truth: Are Dragon Tongue Beans Green Beans?
At a foundational level, yes, dragon tongue beans are a type of green bean. The term "green bean" is a broad, common name that refers to the edible pod of various cultivars of the species Phaseolus vulgaris. This species also includes many other familiar beans, such as pinto and kidney beans, but dragon tongue is a snap bean variety—meaning the pod is meant to be eaten whole when young and tender. While their colorful appearance might suggest otherwise, their botanical classification confirms their place in the green bean family.
What Makes Dragon Tongue Beans Unique?
Despite their family ties, dragon tongue beans are far from a carbon copy of a standard green bean. They are a Dutch heirloom variety, sometimes known as 'Dragon Langerie,' and prized for their unique characteristics.
- Appearance: Unlike the uniform green of typical varieties, raw dragon tongue beans have a creamy yellow or pale green pod, stunningly adorned with vibrant purple or burgundy streaks and mottling.
- Flavor and Texture: They are renowned for their sweet, juicy, and subtly nutty flavor, which many find more complex than a common green bean. The pods are typically wider and flatter than cylindrical green beans and are notably stringless and tender.
- Versatility: This variety is exceptionally versatile. When young, the pods can be eaten as a fresh snap bean, but if left to mature on the vine, they can be shelled and used as a dried bean.
Culinary Uses and Cooking Dragon Tongue Beans
Cooking dragon tongue beans is straightforward and similar to green beans, but with one surprising difference: the color. The beautiful purple streaks fade almost completely when cooked, leaving the pods a solid creamy yellow. This color change is a natural process and no cause for alarm.
Here are some popular ways to prepare them:
- Blanching: A quick blanch in boiling water and an ice bath preserves their crispness. The color will change, but the flavor remains.
- Sautéing and Stir-frying: This is an excellent method for highlighting their buttery, nutty flavor. They cook quickly and maintain a tender-crisp texture.
- Roasting: Roasting with a little olive oil, salt, and pepper brings out a deep, savory sweetness. The high heat can add a pleasing char.
- Raw: Unlike some other beans, dragon tongue beans are particularly delicious when eaten raw. Their sweetness and tender texture make them a fantastic addition to salads and vegetable platters.
- Pickling: Their crispness makes them a perfect candidate for pickling, creating flavorful dilly beans.

Growing and Sourcing Dragon Tongue Beans
For the avid gardener or home cook, growing dragon tongue beans is a rewarding experience. As a bush variety, they do not require a trellis and produce pods in a relatively short time, often around 60 days to maturity. The plants are beautiful, with purple flowers preceding the stunning streaked pods. When harvesting, the key is to pick them when the pods are around 6–7 inches long for optimal tenderness.
For those who prefer to source them, look for them at local farmers' markets or specialty grocers during the growing season. Their unique look makes them stand out from the other produce. You can also find high-quality seeds online from reputable heirloom seed companies like Baker Creek Heirloom Seeds.
