(Zinnia elegans) Magnificent when in bloom and easy to grow, this beautiful, large-flowered strain of zinnia is from Ernst Benary, one of the oldest German seed companies (founded in Erfurt in 1843). Its fully double blossoms measure 4-5″ across and come in a wide array of colors. The long stems of this annual make it ideal for use in arrangements and bouquets. Annual, 3-4′ tall.
