Botanical Overview
Horehound is maintained at Green Grass Grove as gray aromatic dryland herb. The record is anchored to Marrubium vulgare and is managed in gritty raised herb bed or container. North Florida heat, humidity, sandy soils, storm rainfall, and occasional freezes are addressed through crop-specific placement and protection. Scouting, photographs, accession notes, and survival records should be attached to the exact plant or seed lot rather than generalized across the catalog. humid summer crown survival and self-seeding require monitoring.
Why We Feature This Specimen
Horehound gives Green Grass Grove a focused living record for gritty raised herb bed or container, with climate response, propagation, scouting, safety, and specimen history tracked together.
Climate & Protection
Cold protection trigger: Begin cold protection below 38 °F. The cold-damage threshold is the lower temperature where injury becomes likely, not the recommended waiting point.
Sun / Light: Full sun to partial shade according to the habitat and heat response described in this profile.
Manage according to North Florida seasonality. humid summer crown survival and self-seeding require monitoring.
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 ↗Plant or move outdoors when conditions match gritty raised herb bed or container and the accession is not exposed to avoidable cold or heat shock.
Establish during the season appropriate to gritty raised herb bed or container, with freeze, heat, and hurricane timing considered.
Spacing: Allow the mature width and necessary airflow; adjust nursery spacing as the specimen grows.
Planting Depth: Set transplants at the original crown or root-flare depth; sow seed only to species-appropriate depth.
Pollination: Insect pollinated.
Water, Soil & Nutrition
💧 Water & Moisture
Use an irrigation pattern appropriate to gritty raised herb bed or container; maintain root oxygen and avoid abrupt drought or storm saturation.
Consistent moisture appropriate to the crop, with drainage or aquatic containment as specified.
Provide airflow and dry foliage promptly after irrigation or rain; protected specimens require regular pest scouting.
🌱 Soil & Growing Media
Preferred pH: 5.50 to 7.50
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use soil- or solution-test-based fertility. Avoid universal N-P-K recipes and excessive nitrogen.
Diagnose pH, roots, water status, and tissue pattern before fertilizing; environmental injury can mimic deficiency.
Growth, Maintenance & Harvest
Maintenance & Pruning
Remove dead, diseased, storm-damaged, or intentionally harvested growth with sanitized tools; preserve the natural form and accession identity.
Harvest or Observation
Bitter leaves used sparingly as flavoring. Harvest only clean, correctly identified, legally permitted material and retain accession records.
Storage & Preservation
Maintain labeled seed, propagules, or a living backup according to the species; prevent moisture damage, contamination, and unauthorized distribution.
Harvestable Plant Parts & Uses
Bitter leaves used sparingly as flavoring. Keep harvest identity, treatment history, and storage records attached.
Propagation, Cloning & Tissue Culture
Propagation Methods
Stem Cuttings
Stem cuttings are an umbrella vegetative method in which a detached section of stem containing one or more nodes is induced to form adventitious roots and an independent…
Open Full Method ↗Division
Division is the umbrella vegetative method of separating an established plant into two or more self-supporting units, each with the buds, shoots, roots, and storage tissues required for…
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 ↗Aquaponics, Hydroponics & Aeroponics
Aquaponics
Use only in contained systems when food safety, root oxygen, toxicology, and nutrient loading are compatible.
Hydroponics
Use only where the crop's root form and safety allow; unsupported universal nutrient recipes are omitted.
Aeroponics
No profile-specific operating notes have been recorded.
Pests, Diseases, Safety & Toxicology
Inspect horehound for aphids, mites, whiteflies, leaf miners, and chewing insects. Dense, dusty, or drought-stressed plants can conceal infestations.
Root and crown rots are the main preventable disease risk in wet soil; also monitor for leaf spots and powdery mildew where airflow is poor.
Grow horehound in sun and sharply drained soil, shear after flowering when seed spread is not desired, and monitor escapes because the species can naturalize.
Humid summer crown survival and self-seeding require monitoring. Additional risks include poor identification, incorrect irrigation, weak airflow, and loss of accession records.
Culinary or medicinal use is not inferred from cultivation. Concentrated preparations, pregnancy-related use, drug interactions, and dosage require qualified clinical guidance.
Humid summer crown survival and self-seeding require monitoring. Follow pesticide labels, legal restrictions, and public/private visibility controls.
