At a glance
Toothache plant is frost-sensitive and even a light freeze will kill established plants, so gardeners in cooler climates should not transplant outdoors until all frost risk has passed and soil temperatures are consistently warm.

Step-by-step planting
Growing toothache plant from seed rewards patience and attention to warmth, since germination and early development are closely tied to consistent temperature and moisture conditions that vary by location and season.
-
1
Start Seeds Indoors
Sow paracress seeds indoors 6 to 8 weeks before your last expected frost date, pressing them onto the surface of a fine, moist seed-starting mix since they need light to germinate and should not be buried.
-
2
Maintain Warmth
Keep the seed tray at a consistent soil temperature of 70 to 75 degrees Fahrenheit using a heat mat if needed, as cooler conditions slow germination considerably and can lead to uneven sprouting.
-
3
Keep Moisture Consistent
Mist the surface gently to keep the growing medium evenly moist but not waterlogged, since toothache plant seeds are small and a drying-out period during germination can interrupt the process entirely.
-
4
Provide Bright Light
Once seedlings emerge, move them under grow lights or to a very bright south-facing window, keeping lights close to prevent the leggy stretching that weakens young electric daisy herb seedlings.
-
5
Harden Off Before Transplanting
Spend 7 to 10 days gradually introducing seedlings to outdoor conditions by setting them outside for increasing periods each day, starting in a sheltered spot before exposing them to full sun and wind.
-
6
Transplant to the Garden
Choose a location with full sun and rich, well-draining soil, spacing toothache plant care-tested transplants about 12 inches apart to allow room for their spreading, mounding growth habit.
-
7
Water and Harvest Regularly
Keep the soil consistently moist during hot weather and begin harvesting flower heads as soon as they form, since regular picking encourages the plant to produce more buzz buttons throughout the season.

Frequently asked
Questions about Toothache Plant Seeds – A
How long do toothache plant seeds take to germinate?
Under warm conditions with soil temperatures around 70 to 75 degrees Fahrenheit, toothache plant seeds often begin to sprout within 7 to 14 days, though this varies depending on seed freshness, moisture consistency, and your specific growing environment. Cooler or fluctuating temperatures can stretch that window significantly, so a heat mat is worth using if your home runs cool.
Can toothache plant grow in containers?
Yes, toothache plant does well in containers as long as the pot is at least 10 to 12 inches wide and has good drainage, since the plant spreads outward rather than growing tall and appreciates room to fill out. Use a rich potting mix and be prepared to water more frequently in containers, especially during warm weather, as they dry out faster than garden beds.
Is the toothache plant edible?
The flowers, leaves, and stems of Acmella oleracea are all edible and have a long history of culinary use in parts of South America and Southeast Asia, where the leaves are added to salads and the flowers are used as a tongue-tingling garnish. The spilanthol herb produces a strong numbing and buzzing sensation, so a little goes a long way in cooking.
What does the toothache plant taste like?
Chewing a buzz buttons flower produces an immediate, intense tingling and numbing sensation on the tongue and lips, followed by a burst of saliva, which is part of why it has become popular in experimental cuisine and cocktail garnishes. The flavor itself is herbal and slightly citrusy before the numbing effect takes over, which typically fades after a minute or two.
Does toothache plant come back every year?
In tropical and frost-free climates, Acmella oleracea behaves as a short-lived perennial and can return or self-seed reliably from year to year. In temperate climates with frost, it is grown as an annual and must be replanted each season from fresh paracress seeds or started indoors ahead of the warm season.
When should I start toothache plant seeds indoors?
Start toothache plant seeds indoors 6 to 8 weeks before your average last frost date, which gives seedlings enough time to develop before transplanting into warm outdoor soil. Since this is a heat-loving plant, it is worth waiting until nighttime temperatures are reliably above 50 degrees Fahrenheit before moving seedlings outside.
Is toothache plant safe for pets?
Toothache plant is not well documented in standard veterinary toxicology databases, and definitive safety data for pets is limited, so it is wise to keep curious pets away from the plant as a precaution. The spilanthol compound that causes numbing in humans may cause discomfort or irritation in animals if ingested, and a veterinarian should be consulted if you have specific concerns about your pet.
