Bean / Dragon's Tongue
Phaseolus vulgarisBean / Dragon's Tongue is preserved as a distinct wax horticultural bean with purple-streaked pods for nursery, accession, crop, harvest, scouting, and public-education records.
Botanical Overview
Bean / Dragon's Tongue is preserved as a distinct wax horticultural bean with purple-streaked pods for nursery, accession, crop, harvest, scouting, and public-education records.
Why We Feature This Specimen
Bean / Dragon's Tongue turns specialty-bean row into a measurable Green Grass Grove record connecting identity, North Florida performance, harvest quality, and preservation.
Climate & Protection
Cold protection trigger: Begin cold protection below 50 °F. The cold-damage threshold is the lower temperature where injury becomes likely, not the recommended waiting point.
Sun / Light: Full sun, with light afternoon shade only where summer heat would otherwise reduce crop quality.
Direct sow in warm soil during spring or late summer; extreme heat can reduce flower and pod set.
Planting & Seasonal Guide
Starting & Germination Methods
Seed Sowing
Seed sowing is the umbrella operational method for placing botanical seed into a germination environment. It includes selection of containers or beds, medium, depth, spacing, moisture, temperature, light,…
Open Full Method ↗Direct Seed
Direct Seed is retained as a legacy identity for placing seed directly into its final production container, bed, plug position, restoration cell, or growing location without first raising…
Open Full Method ↗Use the verified seasonal window for this crop and harden or acclimate transplants before exposure.
Plant in the crop-appropriate North Florida window, avoiding predictable frost, extreme heat, or saturated storm periods.
Spacing: Provide at least the room implied by the mature width (12–18 in) plus necessary airflow and harvest access.
Planting Depth: Sow or set at crop-appropriate depth; keep crowns, corms, root flares, and graft unions correctly positioned.
Pollination: Most beans and peas self-pollinate but bees can improve activity. Peanuts flower above ground then peg into soil, so loose soil and undisturbed pegging zone matter.
Water, Soil & Nutrition
💧 Water & Moisture
Maintain even moisture through flowering and pod fill without saturating the root zone. Water at soil level and reduce prolonged leaf wetness.
Consistent moisture appropriate to the crop and growth stage.
Use airflow, morning irrigation, sanitation, and crop-specific spacing to reduce humid-season disease.
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use soil-test-based fertility and avoid excessive nitrogen, which can favor foliage over pods and reduce the benefit of Rhizobium-associated nitrogen fixation.
Check pH, roots, moisture, nematodes, disease, and crop stage before diagnosing a nutrient shortage.
Growth, Maintenance & Harvest
Maintenance & Pruning
Use only crop-appropriate pinching, trellising, desuckering, leaf removal, or cleanup with sanitized tools.
Harvest or Observation
Pick tender pods frequently or allow pods to dry fully for shell and seed use.
Storage & Preservation
Cool fresh produce promptly or dry seed and grain to safe storage moisture. Preserve named cultivars through biologically correct seed, clone, graft, or accession methods.
Harvestable Plant Parts & Uses
Pick tender pods frequently or allow pods to dry fully for shell and seed use.
Propagation, Cloning & Tissue Culture
Propagation Methods
Direct Sowing
Direct sowing is the establishment of plants by sowing seed outdoors or into the final production bed rather than transplanting nursery-grown seedlings. It is a complete site operation…

Open Full Method ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Use only with adequate root oxygen, crop-specific mineral supplementation, pest exclusion, and food-safety controls.
Hydroponics
Use only where root support, crop duration, sanitation, and nutrient monitoring are appropriate; universal N-P-K formulas are omitted.
Aeroponics
No profile-specific operating notes have been recorded.
Pests, Diseases, Safety & Toxicology
Scout Bean / Dragon's Tongue for bean leaf beetles, Mexican bean beetles, aphids, whiteflies, mites, thrips, leaf miners, cutworms, and pod-feeding insects. Protect pollinators and natural enemies and confirm the pest before treatment.
Monitor Bean / Dragon's Tongue for damping-off, root rots, anthracnose, rust, bacterial blights, mosaic-like symptoms, and seedborne disease. Use clean seed, crop rotation, airflow, root-zone watering, and prompt removal of diagnosed plants.
Direct-sow Bean / Dragon's Tongue into warm soil, avoid disturbing roots, provide a trellis where climbing growth occurs, harvest promptly for the intended fresh-shell or dry-bean stage, and remove diseased residue. Do not save seed from off-type or symptomatic plants.
Bean / Dragon's Tongue is most likely to fail from crop-specific timing errors, poor drainage, unverified identity, climate stress, or missed scouting.
Raw or undercooked common beans contain harmful lectins; dry beans require thorough boiling.
