Roselle is an annual plant that grows up to 6 feet tall. It has green leaves, and the flowers are red with a characteristic bulbous shape. The fruit is a fleshy red calyx that surrounds the seedpod.
Roselle requires a warm, humid climate with temperatures between 60°F and 90°F. It is typically grown in tropical and subtropical regions, but can also be grown in temperate regions during the summer months. Roselle is best grown in well-draining soil with a pH between 5.5 and 6.5.
Roselle seeds typically germinate within 7-10 days, but can take up to 21 days depending on growing conditions.
The fruit of the roselle plant is typically harvested when it turns a deep red color, which usually occurs 90-100 days after planting. The calyx is separated from the seedpod and can be used fresh or dried for later use.
Roselle is high in vitamin C, antioxidants, and polyphenols. It is also a good source of fiber, calcium, and iron.
