About

The Purple Thai pepper is a distinctive Capsicum annuum variety from Thailand. Its slender, tapered pods measure 3–4 inches (7.5–10 cm) long and ripen from deep purple to bright orangish-red. The plant grows to about 3 feet tall, is highly productive, and performs especially well in containers. It delivers a clean, sharp heat with citrusy and fruity undertones—brighter and fruitier in the purple stage, deeper when fully red—making it ideal for authentic Thai and Southeast Asian dishes.

Backstory

A rare gem from the Thai pepper family originating in Thailand, this variety was popularized in the US by seed catalogs for its vibrant color, container-friendly growth, and excellent flavor-heat balance.
