Toothache Plant / Paracress
Acmella oleraceaToothache Plant / Paracress is preserved as a distinct toothache plant / paracress for habitat, nursery, harvest, safety, propagation, and education records.
Botanical Overview
Toothache Plant / Paracress is preserved as a distinct toothache plant / paracress for habitat, nursery, harvest, safety, propagation, and education records.
Why We Feature This Specimen
Toothache Plant / Paracress connects specimen identity, North Florida performance, seasonal care, ecological function, and preservation inside 3G-GroveOS.
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 to partial shade according to species, with strong light for fruiting and carnivorous plants.
Requires species-appropriate moisture, airflow, seasonal timing, and harvest discipline.
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 ↗Requires species-appropriate moisture, airflow, seasonal timing, and harvest discipline.
Spacing: Allow the expected mature spread (12–24 in) plus storm, pruning, pollination, habitat, and harvest access.
Planting Depth: Set seed, crowns, rhizomes, root flares, graft unions, and bog crowns at species-appropriate 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
Maintain evenly moist but aerated soil during establishment and flowering. Avoid prolonged drought, standing water, and wet foliage late in the day.
Consistent moisture matched to species and season.
Use airflow, sanitation, spacing, and protected placement to reduce foliar disease, rot, and postharvest decline.
🌱 Soil & Growing Media
Preferred pH: 5.50 to 7.20
↘ Drainage & Root-Zone Behavior
✦ Nutrition & Deficiency Checks
Use light, balanced fertility based on soil or media tests. Excess nitrogen produces weak growth with reduced flowering.
Check pH, roots, irrigation water, temperature, and accession biology before diagnosing nutrient deficiency.
Growth, Maintenance & Harvest
Maintenance & Pruning
Use species-appropriate training, deadheading, division, canopy pruning, cane renewal, or sanitary removal with clean tools.
Harvest or Observation
Harvest clean leaves, flowers, calyces, or shoots while preserving enough plant for regrowth.
Storage & Preservation
Cool edible harvests promptly; dry seed or botanical material completely; maintain labeled backup plants, rhizomes, cuttings, grafted stock, or tissue-culture material.
Harvestable Plant Parts & Uses
Harvest clean leaves, flowers, calyces, or shoots while preserving enough plant for regrowth.
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 ↗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
Not recommended unless a species-specific contained research design addresses root oxygen, safety, mineral load, and containment.
Hydroponics
Use only where root form, crop duration, safety, and support are compatible. Carnivorous and restricted specimens are excluded from ordinary nutrient systems.
Aeroponics
No profile-specific operating notes have been recorded.
Pests, Diseases, Safety & Toxicology
Scout toothache plant for aphids, whiteflies, thrips, mites, caterpillars, slugs, and chewing beetles, especially in dense or protected culture.
Monitor for damping-off, root and crown rots, bacterial and fungal leaf spots, and powdery mildew where airflow is poor.
Pinch or harvest shoots to maintain branching, deadhead or retain seed according to the propagation goal, preserve airflow, and keep medicinal or culinary claims separate from horticultural identification.
Toothache Plant / Paracress most often fails from wrong identification, poor siting, climate stress, lost provenance, restricted-use violations, or missed scouting.
Flower heads can cause pronounced oral tingling or numbness. Food or medicinal use is not inferred from cultivation; allergy, pregnancy, drug interaction, and dosage questions require qualified guidance.
Use only confirmed food parts; stinging hairs, caffeine, allergy, or oral numbness may apply. Follow pesticide labels, legal restrictions, access controls, provenance rules, and species-specific food guidance.
