Fringed or ruffled petals, attractive color selection, and sweet-spicy fragrance – not to mention the endless stunning floral arrangements it can be a part of – are just a few of the many reasons the carnation is top-tier in the world of flowers. There’s no doubt why it’s dubbed the “flower of the gods” and holds the record as the second most popular flower worldwide. Read on below to learn more about this stunning ornamental, including the native range of carnation flowers, ideal growing zones, and other interesting facts.
Where do Carnations Grow Natively? Key Takeaways
Carnation flowers, scientifically known as Dianthus caryophyllus, are native to the Mediterranean region, specifically the areas of Southern Europe, including Spain, Italy, and Greece. Today, carnations are grown in many parts of the world and are a popular choice for floral arrangements, bouquets, and gardens due to their beauty, symbolic value, and longevity. Carnations grow best in USDA hardiness zones 7 to 10.
Get to Know Carnations: Where are Carnation Plants Native to?
Carnations are one of the oldest flowering plants in cultivation, with reports of this perennial being cultivated by the Greeks and Romans dating back to 2,000 years ago. Because of this, the exact native origin of carnations is challenging to determine.
Many believe, however, that carnations originated in the Mediterranean region of Europe and Asia. The now highly sought flowering plants reached the United States through Long Island, New York, in 1852 as part of the French flower shipment.
Carnations are technically classified into two types: wild carnations and border carnations. Wild carnations are simply those that grow in the wild, while border carnations are those that are hybrid cultivars produced mainly for commercial cut flower usage. To date, there are about 300 known species of carnations worldwide. Wild carnations, on the other hand, are currently a rare find.
Although the common name “carnation” technically refers to the Dianthus caryophyllus species, it is also used for the cultivated varieties between D. caryophyllus and other Dianthus species.
Dianthus Growing Zones
Carnations, being popular ornamentals for garden and commercial uses as cut flowers, are widely cultivated across the globe. They grow almost anywhere as the plants adapt to any climate.
However, carnations grow best in USDA hardiness zones 7 to 10. While other Dianthus species are more cold-hardy, you can expect carnation’s optimum growth and plant performance in areas where temperatures do not drop below 0 degrees F or above 40 degrees F.
A recognized variety of other Dianthus species known as the Desmond Dianthus (Dianthus plumarius ‘Desmond’) or Desmond Carnation is one of the few Dianthus plants that thrive in colder areas. It is hardy in USDA hardiness zone 4 to 8. The Hardy Mixed Carnations, on the other hand, are hardy in USDA hardiness zone 3 to 9.
When growing carnations, note that the ideal daytime temperature should be between 50 to 59 degrees F and 41 to 46 degrees F for nighttime temperature. Growing conditions with temperatures outside these ranges would most likely prohibit growth if not damage the carnations.
Planting carnations outside their ideal hardiness zones may not be the best idea, but it is still doable. But make sure to take into consideration several measures to ensure plant growth. For instance, plant in an area with approximately six hours of full sun and good drainage. Carnations can also be easily propagated and transplanted throughout the garden.
