Overview of Dragon Tongue Beans
-
Dragon tongue is a bush-type green bean that matures quickly in 55-60 days
-
Plants reach 2 to 2 1/2 feet tall and wide, producing long, flattened pods.
-
Raw pods emerge pale green and develop vivid purple stripes when mature.
-
Each pod contains 4-6 beans streaked with pink or purple.
-
Beans have a sweet, nutty taste and creamy texture perfect for eating fresh.
-
With extra time on the vine, pods can also be used as shelling or dried beans.
Knowing the growth habits and physical characteristics of this variety helps determine optimal harvest times.
Harvest Stage 1: Snapping Beans (55-60 Days)
For use as snap beans:
-
Begin checking plants daily once flowers start fading after blooming.
-
Look for young, slender pods around 3-5 inches long.
-
Harvest pods that have developed purple striping on cream or pale green skin.
-
Beans should snap crisply when bent. Pods feel firm but plump, not bulging with seeds.
-
Use scissors or break pods off by hand to avoid damaging plants.
-
Pick every 2-3 days to encourage further pod production.
Picked at this young stage, dragon tongue pods are flavorful, stringless, and perfect for sautéing or steaming.
Harvest Stage 2: Green Shelling Beans (60-70 Days)
For use as green shelling beans:
-
Allow pods on plants to size up, reaching 5-8 inches in length.
-
Harvest when the purple striping darkens and beans inside fill out pod.
-
Beans will be plump and nearly full grown, but not dried out.
-
Open pods and remove beans for fresh use without cooking pods.
-
Store unshelled beans in refrigerator up to 1 week.
Once seeds start enlarging inside, pods become fibrous so green shelling captures plump beans.
Harvest Stage 3: Dry Shelling Beans (70-90 Days)
For use as dry shelling beans:
-
Leave pods on plants until fully mature and beans harden.
-
Pods turn brown and crispy while beans solidify and stripes get very dark.
-
Allow pods to dry thoroughly on plants before picking.
-
Pull up entire plants and hang indoors or pick individual pods.
-
Remove shells, then spread beans in a single layer to finish drying.
Dry shelling produces beans for storage and requires extended vine drying before shelling.
What Color are Dragon Tongue Pods When Ready to Pick?
-
Immature pods are pale green, cream, or yellowish.
-
Purple, red, or pink striping develops on pods as beans mature inside.
-
Ideal snap bean stage shows vivid streaks on lighter green pods.
-
Leave pods on plants until stripes become very dark for shelling use.
-
Fully dried pods for shelling turn completely brown.
Following the color changes in pods indicates the stage of maturity for harvesting.
