Dahlias are vibrant, flowering plants native to Mexico and Central America. They belong to the Asteraceae family and are known for their stunning blooms, which come in various shapes, sizes, and colors. These flowers typically bloom from mid-summer to the first frost, making them a popular choice for gardens and floral arrangements. Dahlias thrive in well-drained soil and require full sunlight for optimal growth. They can be grown from tubers, which are underground storage organs, and are often divided to propagate new plants. With proper care, dahlias can reach heights of up to six feet and produce flowers that can be as large as a dinner plate.
