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

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.
