Thai Hot Pepper

Capsicum frutescens

The Story

Plant Bio

Capsicum frutescens is the pepper species behind tabasco and most Thai hot types, an erect warm-season plant from Bolivia and western Brazil reaching four to six feet where the season is long enough. Dark green leaves four to eight inches long clothe branching stems, and small fruits are held upright rather than hanging.

The upright-pointing fruit is the giveaway that separates this species from the drooping fruit of most peppers, and it is why tabasco peppers are picked so easily. It is a true perennial in frost-free conditions and will grow into a woody shrub over several years, cropping far more heavily than a first-year plant ever does.

Uses & Benefits:

Ornamental UsesUpright fruit in vivid red, orange and yellow held above the foliage rather than hanging.
Practical UsesThe species behind tabasco and Thai hot peppers, and productive for several years if overwintered.
Ecological BenefitsSongbirds eat the fruit unharmed, being immune to capsaicin, and spread the seed.

Planting

How to Grow

  1. Start seed indoors ten weeks before the last frost.
  2. Germinate at 80F; germination is slow.
  3. Plant out only once nights are reliably warm.
  4. Give it full sun and freely drained soil.
  5. Overwinter the plant indoors to crop again.
  6. Wear gloves when handling the ripe fruit.

Pro Tip

Overwinter it rather than starting again — a second or third year plant crops far more heavily than any first-year seedling.
