Connecting specimen records, habitat data, and the living archive.
Nasturtium
Tropaeolum majus L.Nasturtium is reconstructed as a distinct nasturtium for culinary, nursery, pollinator, seed, propagation, harvest, and public-education records.
Botanical Overview
Nasturtium is reconstructed as a distinct nasturtium for culinary, nursery, pollinator, seed, propagation, harvest, and public-education records.
Why We Feature This Specimen
Nasturtium adds aroma, flavor, bloom, and specimen history to Green Grass Grove while keeping accession identity and responsible use attached to the plant.
Climate & Protection
Sun / Light: Full sun to partial sun according to the species; afternoon shade may protect cool-season or moisture-loving herbs.
Nasturtium is managed as a flower-and-herb crop with pollinator access, clean food-production practices, and seasonal timing appropriate to North Florida. Leaves, flowers, and immature seed are pungent edible parts from untreated plants.
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 ↗Indoor Seed Starting
Indoor seed starting produces transplants in containers under managed temperature, light, moisture, sanitation, and spacing before outdoor or greenhouse establishment. It extends the production season, protects valuable seed,…
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 ↗Nasturtium is managed as a flower-and-herb crop with pollinator access, clean food-production practices, and seasonal timing appropriate to North Florida. Leaves, flowers, and immature seed are pungent edible parts from untreated plants.
Spacing: Allow the expected mature spread (2–6 ft spread) plus airflow and harvest access; contain rhizomatous mints physically.
Planting Depth: Sow small seed shallowly and set crowns, divisions, cloves, rhizomes, and woody root flares at their previous depth.
Pollination: Observe whether flowers set fruit naturally. Add notes if hand pollination, multiple varieties, wind pollination, insect activity, or male/female flower timing affects production.
Water, Soil & Nutrition
💧 Water & Moisture
Keep evenly moist through establishment and flowering without saturating the crown or wetting flowers late in the day.
Use airflow, early irrigation, sanitation, and uncrowded spacing to reduce leaf spots, mildew, crown rot, and postharvest decline.
🌱 Soil & Growing Media
Preferred pH: 5.80 to 7.50
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use modest soil-test-based fertility. Excess nitrogen reduces aroma, weakens stems, increases pests, or delays flowering in many herbs.
Check pH, root condition, irrigation, temperature, and container restriction before diagnosing nutrient deficiency.
Growth, Maintenance & Harvest
Maintenance & Pruning
Use clean pinching, deadheading, division, woody renewal, or postharvest cleanup appropriate to the species. Do not shear diseased wet foliage.
Harvest or Observation
Harvest clean flowers, leaves, or seed at the profile-specific stage from untreated plants, leaving enough bloom for pollinators.
Storage & Preservation
Dry herbs quickly with airflow or refrigerate fresh material. Store seed, cloves, rhizomes, or cuttings with complete accession labels.
Harvestable Plant Parts & Uses
Harvest clean flowers, leaves, or seed at the profile-specific stage from untreated plants, leaving enough bloom for pollinators.
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 ↗Seed
Seed is retained as an umbrella propagation identity for sexual reproduction through mature botanical seed. A seed normally contains an embryo, stored reserves or nutritive tissue, and protective…
Open Full Method ↗Transplant
Transplant is a nursery handling process that moves an established seedling, rooted cutting, division, grafted plant, or tissue-culture plantlet from one container or site to another. It is…
Open Full Method ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Use only with adequate root oxygen, mineral balance, pest exclusion, and harvest sanitation.
Hydroponics
- Target pH5.8–6.5
- Target EC1.0–1.8 mS/cm
Use only where root form, crop duration, drainage preference, and food safety are compatible. Universal N-P-K formulas are omitted.
Aeroponics
No profile-specific operating notes have been recorded.
Pests, Diseases, Safety & Toxicology
Use the validated live pest relationships assigned to this herb group, while recording cultivar-specific susceptibility and pollinator use.
Use the linked live disease and disorder records; separate infection from summer heat, waterlogging, drought, frost, and nutrient stress.
Apply the linked integrated management, sanitation, quarantine, pollinator, containment, and recovery plans.
Nasturtium most often fails from inappropriate moisture, poor airflow, wrong seasonal timing, lost accession identity, or excessive harvest.
Edible-flower use requires confirmed identity, food-crop production, allergen awareness, and exclusion of pesticide-treated ornamentals.
Edible-flower use requires confirmed identity, food-crop production, allergen awareness, and exclusion of pesticide-treated ornamentals. Follow pesticide labels, allergen cautions, pet-safety guidance, and responsible medicinal-use boundaries.
