Carnation, variety and care

Carnation, variety and care: what are the varieties of carnation with the most abundant flowering? Here are the varieties of carnations or carnations to grow indoors to get beautiful blooms.

The genreDianthus, commonly calledcarnation, belongs to the Caryophyllaceae family. About 300 different species belong to the genus Dianthus, all herbaceous perennial, biennial and annual plants. Despite the abundance of species and variety of the genus Dianthus, there are only three species of carnations most cultivated. For those who want to get abundantbloomsofcarnations, it is important to underline that these plants, over the years, produce less and less flowers so it will be necessary to "regenerate" them. Every three or four years, you can rejuvenate carnation plants by multiplying them by cuttings or offshoots. Cutting is a technique suitable for a small number of specimens while with the offshoot you can get a large number of daughter plants with minimal effort. For more information on how to multiply carnations by cuttings or offshoots, please refer to the articles:

  • how to make the carnation cutting
  • carnations, propagation and care

The most suitable multiplication technique for carnations can also be chosen based on the time of year you are in. The carnation cutting can be done from August to November, that is, between late summer and autumn. The best time for carnation multiplication by offshoot falls between late spring and mid-summer, that is, from May to early August.

Carnations, varieties and care

As stated, there are approximately 300 species of carnations but the most cultivated are essentially three: theDianthus caryophyllus,thereDianthus chinensisand theDianthus barbatus (carnation of poets).In this paragraph we will list the characteristics, needs and treatments to be given so as to allow you a more thoughtful choice at the time of planting.

Dianthus caryophyllus

From this species, most ofvarietycurrently on the market. All hybrids ofDianthus caryophyllusthey are perennial and bushy carnations. ThereDianthus caryophyllusit is a perennial species that grows up to a height of between 70 and 80 cm.

It produces single and large flowers so it is suitable for growing cut flowers. Flowering goes from late spring to late autumn.

It prefers sunny exposure and well-drained soil.

Dianthus chinensis

Like D. caryophyllus, chinensis is also a carnation perennial. It produces flowers that develop in small clusters. The color of the flowers ranges from pink to red. These flowers are not particularly large and therefore less suitable for those who intend to grow carnations for cutting. Flowering starts from late spring and lasts all summer. Again the plant of carnationneeds a sunny position.

Dianthus barbatus

ThereDianthus barbatusis very well known as the plant of poets or thecarnation of poets. Like the two species already seen, also theDianthus barbatusit's aperennial carnationbut when adapted in pot it is often cultivated as an annual plant. The carnation of the poets reaches a maximum height of 30 cm and is well suited to the creation of flower beds, flower meadows or borders. The small flowers are very colorful and bloom in very small bunches.

Flowering lasts from mid-spring to the end of summer. Under favorable conditions, thecarnation of poetsblooms until mid-autumn. Like allcarnations, also thereDianthus barbatusneeds sunny locations.

Carnations, care and planting

The cultural care to be given to any variety of carnation is very similar. Here are the general guidelines for planting carnations:

  • Avoid compact or crusty soils, better a substrate rich in organic substance composed of a part of sand, in order to favor drainage. If you grow carnation in the open field, finely work the soil with a deep digging and buried well-mature compost and a part of sand.
  • When buying carnations in pots, proceed immediately to repotting: immerse the pots in a bucket of water before final planting.
  • For planting in the open field, make a hole twice the volume of the pot.
  • Plant the root ball with the top at ground level.
  • Fill the hole, then compress the soil slightly without suffocating the collar.
  • Water to naturally settle the earth and if necessary add more soil to bring it to level.
