Purple Top Verbena are a mainstay in any ornamental or cut flower garden. They add dimension to the garden, growing three to four feet tall and dotting it with little vibrant lavender flowers that are as prolific as they are adorable. Purple Top Verbena is one of the best plants for attracting butterflies, particularly the Tiger Swallowtail. These easy-to-grow annuals will often reseed themselves and are hardy to zone 7. Round out your planting by combining them with cosmos, lavender, and purple zinnias.
