Branched St Bernard's-lily
Anthericum ramosum
The Branched St Bernard's-lily is a slender, perennial herbaceous plant reaching heights of 30 to 70 centimeters. It is characterized by a paniculately branched inflorescence bearing numerous white, star-shaped flowers. The narrow, grass-like leaves are arranged basally and are significantly shorter than the flowering stalk. It prefers sunny, calcareous sites such as semi-dry grasslands or open oak forests.
Details
Habitat function
Provides a reliable food source for specialized insects such as wild bees and hoverflies during midsummer.
Nutrient uptake
Low nutrient requirement; highly efficient uptake in nitrogen-poor, calcareous soils.
Food source for
Wild bees (e.g., Halictus species), hoverflies, and various butterflies.
Human use
Used as an ornamental plant in near-natural gardens or rock gardens; historically occasional medicinal attributions with no modern relevance.
Ecology
Ecological role
Important nectar source for insects in dry habitats; contributes to the botanical diversity of nutrient-poor sites.
Natural predators
Occasional grazing by roe deer; caterpillars of some specialized moth species.
Competitor species
Displaced by scrub encroachment (e.g., blackthorn) or highly competitive grasses (e.g., wood small-reed) if habitat management is lacking.
Ecosystem service
Support of pollinator populations; erosion control on calcareous slopes through its root system.
Threats
Habitat loss due to agricultural intensification, eutrophication (nitrogen deposition), and succession following the abandonment of grazing.
Scientific profile
Profile
Reproduction
Generative via seeds; vegetative via short rhizome offsets (tussock formation).
Protection & threats
Main threats
Scrub encroachment and afforestation due to abandonment of land use (succession), eutrophication through atmospheric nitrogen deposition, intensive grazing.
