How Tall Does Zinnia Grow? Knowing the Sizes of Zinnias

The sizes of zinnias vary based on the variety and growth conditions. Some grow as close to the ground as 7 to 12 inches. These shorter kinds may also have a mounding growth tendency for a rounded overall appearance. On the opposite extreme of the zinnias’ height spectrum are some that can reach between 3 and 4 feet. For optimal results, they are occasionally grown with support stakes. It is not uncommon for a tall zinnia plant to have many flowers on its stems and grow between 12 and 18 inches wide.
