Carthusian Pink
Dianthus carthusianorum
The Carthusian Pink is a deciduous, perennial herbaceous plant that reaches heights between 15 and 45 centimeters. It forms dense, terminal clusters of bright purple-red flowers surrounded by brown, leathery bracts. The plant is a typical inhabitant of calcareous dry grasslands, nutrient-poor meadows, and sunny slopes. Its narrow, opposite leaves are fused at the base into a sheath, which helps minimize water loss.
Details
Habitat function
Serves as a nectar source and larval habitat for specialized insect species.
Nutrient uptake
Low nutrient requirement; adapted to extremely nitrogen-poor soils.
Food source for
Butterflies (e.g., Swallowtail, Skippers), Burnet moths, and bumblebees.
Human use
Popular ornamental plant for rock gardens and alpine gardens; historical use in monastic medicine (named after the Carthusian Order).
Ecology
Ecological role
Important nectar plant for butterflies with long proboscises, which are the only insects able to reach the deep-seated nectar.
Competitor species
Displacement by tall grasses in cases of high nutrient input.
Ecosystem service
Enhancement of biodiversity in dry grasslands; pollinator support; erosion control on dry slopes.
Threats
Eutrophication through nitrogen deposition, abandonment of grazing (scrub encroachment), and intensive agricultural land use.
Scientific profile
Profile
Reproduction
Primarily sexual via seeds; vegetative reproduction possible through short rhizomes, leading to tuft formation.
Protection & threats
Main threats
Eutrophication via nitrogen deposition; abandonment of grazing (scrub encroachment); intensive agriculture; habitat fragmentation.
