The Satsuma tree is a type of citrus tree known for producing small, sweet, and seedless mandarin oranges, often called Satsuma mandarins. It is a cold-hardy variety, making it well-suited to cooler climates compared to other citrus trees. The tree typically has glossy green leaves and fragrant white flowers, which later develop into easy-to-peel fruit. Satsumas are prized for their sweet, tangy flavor and are often harvested in late fall or early winter.
