Clove Carnations are not your typical Carnation flower. They are a form of Dianthus / Pinks, which form double petaled blooms in a creamy white coloring. The plants grow to a mature height of roughly 12 to 24 inches tall, displaying 1.5 to 2 inch, white flowers. Clove Carnations are categorized as tender perennial / annual flowering plants. They grow quickly the first year, establishing a deep root system, later wilting with the harsh frosts of winter. If the temperatures aren't too severe, the plants can return the following year. All Carnation seeds sold by Seed Needs are Non-GMO based seed products and are intended for the current & the following growing season. All seeds are produced from open pollinated plants, stored in a temperature controlled facility and constantly moved out due to popularity.
