Lavender / French
Lavandula dentataLavender / French is a French lavender accession for dry, sunny culture; in North Florida, crown drainage and humidity management determine survival.
Botanical Overview
Lavender / French is a French lavender accession for dry, sunny culture; in North Florida, crown drainage and humidity management determine survival.
Why We Feature This Specimen
Lavender / French 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.
Lavender / French should be grown in full sun with sharply drained soil and strong airflow. North Florida humidity and summer rain are usually more limiting than winter cold. More heat tolerant than English lavender but frost and humidity remain concerns.
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 ↗Lavender / French should be grown in full sun with sharply drained soil and strong airflow. North Florida humidity and summer rain are usually more limiting than winter cold. More heat tolerant than English lavender but frost and humidity remain concerns.
Plant in fall through early spring only where drainage is exceptional, or establish in containers that can be sheltered from prolonged summer rain.
Spacing: Space 24–36 inches apart for airflow and harvest access.
Planting Depth: Sow small seed shallowly and set crowns, divisions, cloves, rhizomes, and woody root flares at their previous depth.
Pollination: Most herbs are useful pollinator plants when allowed to flower. Let selected plants flower for bees, beneficial insects, seed saving, or drying flowers.
Water, Soil & Nutrition
💧 Water & Moisture
Water deeply but infrequently after establishment. Keep crowns dry, avoid overhead irrigation, and do not maintain wet mulch against stems.
Water to establish, then allow the root zone to dry partially between irrigations. Keep mulch away from woody crowns.
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 little fertilizer; excess nitrogen and organic matter reduce oil concentration, weaken growth, and increase rot.
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
Cut flower spikes as lower florets open, during dry weather, and dry them quickly in shade with airflow.
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 aromatic leaves or flowering stems during dry weather, never removing more foliage than the plant can replace.

Open Full Method ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Use only with adequate root oxygen, mineral balance, pest exclusion, and harvest sanitation.
Hydroponics
- Target pH5.8–6.8
- 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
Spider mites, spittlebugs, aphids, and whiteflies may occur, especially on stressed container plants.
Phytophthora root rot, crown rot, Botrytis, and leaf spots are favored by wet soil, humidity, and poor airflow.
Use raised mineral media, wide spacing, drip irrigation, light pruning after bloom, and immediate removal of plants with crown rot. Do not overmulch.
Lavender / French most often fails from inappropriate moisture, poor airflow, wrong seasonal timing, lost accession identity, or excessive harvest.
Ordinary culinary or aromatic use requires the correct lavender species and clean production. Essential oils are concentrated products and are outside this Profile.
Use normal culinary quantities only where the species is established as food. Essential oils and concentrated medicinal preparations require separate professional guidance. Follow pesticide labels, allergen cautions, pet-safety guidance, and responsible medicinal-use boundaries.
