Most parts of northern China are resource-based severely water-scarce regions, with per capita water resources of less than 300 cubic meters, only 1/8 of the national average, and far below the international water-scarcity threshold of 1,000 cubic meters per capita. With the vigorous development of landscaping, water consumption for greening is growing ever larger, and this contradiction with the scarce water resources of northern China is becoming increasingly prominent. Dianthus acicularis has good drought tolerance and is an excellent water-saving plant material in landscaping. According to calculations, Dianthus acicularis consumes only 0.

Most parts of northern China are resource-based severely water-scarce regions, with per capita water resources of less than 300 cubic meters, only 1/8 of the national average, and far below the international water-scarcity threshold of 1,000 cubic meters per capita. With the vigorous development of landscaping, water consumption for greening is growing ever larger, and this contradiction with the scarce water resources of northern China is becoming increasingly prominent.

Dianthus acicularis has good drought tolerance and is an excellent water-saving plant material in landscaping. According to calculations, Dianthus acicularis consumes only 0.3 tons of water per square meter per year, and it can still remain lushly green even in dry seasons, greatly reducing the cost of greening maintenance. In addition, Dianthus acicularis overcomes the shortcomings of other dianthus species, whose broad branches and leaves make them prone to lodging; its branches and leaves are fine and dense, and the plant height is only 10 cm. Once it forms a closed turf, it requires no pruning, and its appearance resembles a bluegrass-type lawn, forming a thick grass carpet on the ground, with a very good landscaping effect.

In addition to being water-saving and drought-tolerant, forming turf quickly and tolerating trampling, Dianthus acicularis also offers flowers to enjoy in May and June each year. In some areas of northern China with a favorable microclimate, Dianthus acicularis can remain evergreen without turning yellow in winter. In addition, during the growth of Dianthus acicularis, care should be taken to apply certain agents to prevent diseases such as damping-off.
