About

Capsicum annuum 'Fresno' is a robust annual plant that can reach heights of up to 75 cm. It features broad, mid-green leaves and, during summer, bears small white flowers that develop in the leaf axils. These flowers give way to conical fruits measuring around 7 cm in length. The fruits start off green and mature to a vibrant red, offering a moderate level of heat. They have thin walls, making them suitable for various culinary applications.

About the genus

Capsicum comprises both annual and perennial species characterized by simple, alternate foliage and flowers that are either tubular or bell-shaped. These plants are cultivated primarily for their glossy, multi-seeded fruits, which include varieties such as chili and bell peppers. Additionally, they serve as popular choices for indoor ornamental displays.
