Dianthus acicularis is an excellent drought-tolerant, water-saving groundcover plant
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.
