The carnation, also called chinese carnation, is a perennial plant native to Asia, specifically to regions such as northern China, Mongolia and Korea. It belongs to the family of Dianthus, popularly known as carnations, although the carnation is distinguished by its smaller flowers and branched stemsIts popularity lies in the beauty of its petals and its prolonged flowering period, which extends from spring until well into autumn.

In addition, many varieties give off a pleasant aroma which attracts pollinators such as bees and butterflies, enriching the biodiversity of any green space.
General characteristics of the carnation
- Lifecycle: There are perennial, biennial, and annual carnations. Many cultivated varieties are biennial, meaning they begin developing leaves and stems in the first year and bloom profusely in the second.
- Size: They typically reach a height of between 20 and 50 centimeters, although the most common size is around 25-35 centimeters. This compact size makes them easy to grow in pots, flowerbeds, or planters.

- Flowers: About two to four centimeters in diameter, with five toothed or scalloped petals, they are highly prized for their shape and vibrant colors.
- Flowering: The carnation offers one of the longest blooms among ornamental plants, extending from early spring until well into autumn if grown in optimal conditions.

- Flower: Carnations have smaller, usually flatter flowers, with serrated petals, often in two-tone arrangements or with prominent margins. Carnations, on the other hand, tend to have larger flowers.
- Flowering: Carnations generally begin flowering in their second year, and bloom for a longer period of time, while carnations can bloom in different seasons if conditions are right.
