Grow Yellow Acmella Oleracea: The Electrifying “Toothache Plant” for Home Gardens

About

Yellow Acmella Oleracea, often called the Toothache Plant or Spilanthes, is a unique herbaceous flowering plant known for its golden, cone-shaped blooms and tingling, mouth-numbing properties. Native to South America, this eye-catching plant is both medicinally useful and visually striking, making it a fantastic addition to both herb and flower gardens. The plant contains spilanthol, a natural compound with analgesic and antibacterial effects, traditionally used to relieve toothaches and oral discomfort.

At Seedfella.com, we proudly offer high-quality Yellow Acmella Oleracea seeds for gardeners looking to grow rare and functional plants with multiple benefits.

Why Grow Yellow Acmella Oleracea

This plant is more than just ornamental—it offers medicinal and culinary uses:

  • Natural pain reliever for toothaches, sore throats, and gum issues

  • Unique blooms that add an exotic look to gardens and containers

  • Attracts pollinators like bees and butterflies

  • Edible leaves with a tangy, peppery flavor for salads or teas

  • Easy to grow in warm, sunny climates

  • Known for its immune-boosting and antifungal properties

The Toothache Plant is a conversation starter in any garden and a helpful herb in any home remedy collection.

When to Plant

To get the most out of your Acmella Oleracea:

  • Start seeds indoors 6–8 weeks before the last frost date

  • Sow directly outdoors when soil temperatures are consistently above 18°C (65°F)

  • Ideal for spring and early summer planting

  • Harvest continues until the first frost in colder climates

Starting early ensures faster flowering and a longer harvest period.

Where to Plant

Yellow Acmella Oleracea thrives in sunny, well-drained locations:

  • Full sun is essential for vibrant blooms and maximum spilanthol content

  • Use containers, raised beds, or garden borders

  • Prefers rich, moist soil with good drainage

  • Suitable for urban balcony gardens or traditional garden beds

  • Space plants 12–18 inches apart to allow airflow and foliage spread

How to Plant

Planting Yellow Acmella Oleracea is easy and rewarding:

  1. Sow seeds on the soil surface; do not bury deeply

  2. Lightly press into moist seed-starting mix

  3. Maintain temperatures of 21–24°C (70–75°F)

  4. Transplant outdoors once seedlings have at least two sets of true leaves

  5. Water gently and regularly to help roots establish

Using organic compost and natural fertilizers promotes vigorous growth.

How to Care

This plant requires minimal effort with maximum reward:

  • Keep soil consistently moist but not soggy

  • Apply mulch to retain moisture and suppress weeds

  • Deadhead spent blooms to encourage more flowering

  • Use an organic liquid fertilizer every 2–3 weeks during the growing season

  • Watch for aphids or mites; treat with neem oil or insecticidal soap

The plant responds well to frequent harvesting and can even be grown as a short-lived perennial in tropical climates.

Companion Plants

Yellow Acmella Oleracea does well with:

  • Calendula – boosts pollination and deters pests

  • Chamomile – complements its medicinal profile

  • Lettuce or spinach – shares similar light and water needs

  • Avoid pairing with plants requiring dry conditions

These companions enhance the garden’s biodiversity and pest resilience.

Harvesting

Harvesting is simple and useful for both culinary and herbal needs:

  • Pick flower buds once they are bright yellow and firm

  • Leaves can be harvested throughout the growing season

  • Harvest in the morning for highest spilanthol content

  • Use fresh or dry the parts in a shaded, well-ventilated area

  • Store dried parts in airtight containers for future use

Uses

Acmella Oleracea is famous for its electrifying and therapeutic qualities:

  • Chewing flower buds creates a tingling, numbing sensation

  • Used in traditional herbal remedies for dental and oral care

  • Edible in small amounts – leaves and buds used in salads, teas, and cocktails

  • In skincare, it’s an ingredient in anti-aging creams

  • Studied for potential antiviral and antimicrobial effects

It’s a functional edible flower that bridges the gap between aesthetics and health.
