Growing in Pots, Balconies & Indoors

The toothache plant, or “buzz button”, is a compact tender plant (usually well under its 1.2 m maximum) grown for its curious yellow-and-red flower heads. The grower does not treat it as a classic houseplant, but a bright, sunny windowsill or patio pot suits it well and it can be brought in over winter.

Quick Details

  • Container Size: 10-20 L (2.5-5 gal), or at least 100-200% bigger than the plant; a shallow, wide pot is preferred
  • Indoor Suitability: Not a classic houseplant, but a very sunny sill can hold it, and it overwinters indoors
  • Best Spot: Full sun; in desert or very hot climates about 85% sun / light shade prevents leaf scorch
  • Soil & Drainage: Free-draining rich mix – potting or peat with perlite, humus and organic matter
  • Watering in Pots: Average; it can go a few weeks dry but does better kept regularly watered

Indoors & On the Windowsill

  • As a windowsill plant: The grower does not call it a houseplant, but it is compact and tender, so a bright, sunny window works – especially to carry it through winter where it is frost-tender.
  • Overwintering: Bring it indoors before frost; it tolerates a short dry spell but keep it lightly watered and in good light.

On a Balcony or Patio

  • Light & water: Give it full sun (a little shade only in desert-hot climates to prevent sunburn). Water at an average rate – pots dry faster than the ground, so check regularly.

Choosing the Pot, Soil & Long-Term Care

  • Pot & drainage: 10-20 L with strong drainage holes; a wide, shallow pot suits its roots.
  • Potting mix: Free-draining and rich – potting or peat with perlite, plus humus and organic matter; a chopped mulch keeps the soil moist.
  • Refreshing: Every few years replace the soil in winter – wash the old soil off the roots, trim the roots and prune the plant back.

Grower’s Container Tip

  • Shallow, wide pot & winter refresh: Choose a wider, shallower pot than usual, and every few years in winter renew it fully – wash the soil from the roots, cut the roots back, prune the top and repot into fresh mix.

Bloom & Edible Flower Guide

Quick Details

  • Bloom Season: Spring, summer and autumn – year-round in frost-free warmth
  • Time to First Bloom: Fast – within roughly two to three months from sowing
  • Flower Appearance: Small, cone-shaped, golden-yellow flower heads (often with a red central eye), like tiny petal-less daisies
  • Edibility: Yes – the flowers are edible and famous for a tingling, numbing “electric” or “buzz” sensation on the tongue

Detailed Blooming Overview

Also called the electric daisy or toothache plant, Acmella oleracea blooms freely over a long season. The little gold flower buds contain spilanthol, which produces a distinctive tingling, saliva-inducing effect – used both as a novelty and as a flavouring.

Flower Characteristics

  • Gumdrop or cone-shaped yellow heads, often with a red eye.
  • Long bloom season; the flowers attract pollinators.

Bloom Care & Thinning

  • For plenty of flowers: Full sun and warm, moist, fertile soil; pinch to keep the plant bushy and pick flowers regularly to encourage more.
  • Using the flowers: Fresh flowers are used in salads, drinks, spice blends, soups and stews – a little goes a long way.
