About this variety

Pepper Seeds - Hot - Thai

Description

The fiery gem of Southeast Asian cuisine. ‘Thai Hot’ peppers produce small, slender fruits that pack a bright, searing heat balanced by a touch of citrusy sweetness. Each pepper ripens from glossy green to vivid red, delivering bold flavor whether fresh, dried, or infused into oils and sauces.

Compact, bushy plants grow 12–18 inches tall and become covered in upright clusters of fruit—ornamental yet intensely productive. The peppers measure 50,000–100,000 Scoville Heat Units, making them perfect for stir-fries, curries, and hot sauces where sharp, clean spice is essential.

A traditional variety long cultivated across Thailand and neighboring regions, this pepper embodies the heart of Southeast Asian flavor—fiery, fragrant, and unforgettable.
