Raspberry varieties can be broadly categorized into two main types: red raspberries and black raspberries. Red raspberries are the most common and are known for their sweet-tart flavor and vibrant color. Popular cultivars include Heritage and Caroline, which are favored for their high yields and disease resistance. Black raspberries are less common but offer a unique taste and are often used in jams and desserts. Notable varieties include Bristol and Jewel, both recognized for their rich flavor and dark color. Each variety has specific growing requirements, making it essential for gardeners to choose the right type for their climate.
