History
Shishito peppers are a Japanese variety that likely developed from Portuguese peppers introduced to Japan in the 16th century. The name "shishito" translates to "lion head" in Japanese, referring to the wrinkled tip of the pepper that resembles a lion's face. For centuries, shishitos remained a relatively obscure Japanese ingredient, commonly served as an izakaya (Japanese pub) snack blistered in a hot pan with oil and salt. The pepper's crossover to American cuisine began in the early 2000s, when upscale restaurants in cities like New York and San Francisco began featuring them as appetizers. Their appeal was multifold: the simple preparation, the pop of flavor when blistered, and most importantly, the "Russian roulette" element—while most shishitos are mild, roughly one in ten develops significant heat, creating a game of culinary chance that delights diners. By 2015, shishitos had become ubiquitous on American gastropub menus, and Trader Joe's began selling them bagged in their produce section, bringing them to the mainstream. The pepper's thin walls and small size make it perfect for quick high-heat cooking, and unlike most peppers that require peeling after charring, shishitos are eaten whole—blistered skin and all. Today, shishitos represent one of the most successful recent additions to American vegetable consciousness.

upright
Germination
7-14 days
Good germination. Bottom heat (75-80°F) helpful. Cotyledons emerge with typical pepper appearance.
Seedling Stage
Duration: 3-4 weeks
True leaves: First true leaves appear 2-3 weeks after germination with slightly wrinkled edges
Transplant ready: Ready when 4-5 inches tall with 4-6 true leaves
Vegetative Growth
Duration: 4-5 weeks
Bushy plants develop. Feed regularly for strong growth.
Flowering
Timing: 5-7 weeks after transplant
Duration: 2-3 weeks
Self-pollinating with small white flowers. Good fruit set in moderate temps.
Fruit Development
Begins: 7-10 weeks after transplant
Duration: 2-3 weeks per pepper
Small, wrinkled peppers develop quickly. Green to red progression if left.
Harvest Maturity
Timing: 60-75 days from transplant
- Peppers reach 2-4 inches long
- Bright green with wrinkled texture
- Firm but slightly pliable
- Easy to pick from plant
Per Plant
50-100+ peppers per plant over the season
Per Square Foot
25-50 peppers
Harvest Frequency
Every 3-5 days once fruiting begins
Factors Affecting Yield
