Zinnias are a close relative of daisies and are members of the Asteraceae family. Zinnias are grown as annuals due to their bright colors and ease of growth. Zinnia leaves have a rough texture because they are densely covered with short hairs. They are roughly triangular in shape and are located directly opposite each other on the flower stalk. Each stem produces a terminal flower, which can be double or single. Flowering in a range of colors, including deep purples and rich reds, as well as pale corals and white. Strong colors, on the other hand, fade quickly in direct sunlight. Zinnias bloom from July to September, with some blooming as late as October.
