Astrantia is a genus of perennial plants in the family Apiaceae, native to Central Europe, Western Europe, and the Caucasus. The genus name is derived from the Latin word 'aster', meaning "star", referring to the star-like quality of the flower heads. Astrantia species are commonly known as masterworts, a name that reflects their historical use in herbal medicine and alchemy.

Description

Astrantia plants are known for their distinctive inflorescences, which consist of a central umbel surrounded by a ruff of bracts, giving the appearance of a single flower. The actual flowers are small and clustered in the center. The leaves are typically palmate, with a toothed margin. These plants can reach heights of 30 to 90 cm, depending on the species and environmental conditions.

The flowers of Astrantia come in a variety of shades, including white, pink, and red, making them popular in gardens and floral designs. They bloom from late spring to early autumn, offering a long season of interest.

Species

There are several species within the genus Astrantia, including:

• Astrantia major – Great masterwort
• Astrantia minor – Lesser masterwort
• Astrantia carniolica – Slovenian masterwort

Each species has its own specific habitat preferences, but generally, Astrantia species thrive in moist, well-drained soils in partial shade. They are often found in woodland settings or along stream banks in their natural habitats.

Cultivation and Uses

Astrantia is valued in the garden for its unique flower structure, long blooming period, and shade tolerance. They are suitable for use in borders, woodland gardens, and as part of pollinator-friendly gardens. These plants are also noted for their resistance to deer and other herbivores, making them a practical choice in areas where these animals are a concern.

In addition to their ornamental value, Astrantia has a history of medicinal use. The roots were traditionally used in European folk medicine to treat a variety of ailments, although modern science has not extensively studied these properties.

Propagation

Astrantia can be propagated by seed, division, or basal cuttings. Seeds require a period of cold stratification to germinate and can be sown in autumn or after stratification in spring. Division is best performed in either spring or autumn and is a good method for expanding or rejuvenating established clumps. Basal cuttings can be taken in spring and offer another method for creating new plants.

Conservation

While many Astrantia species are not currently considered at risk, habitat destruction and over-collection from the wild for horticultural use or medicinal purposes can pose threats to certain populations. Conservation efforts focus on habitat preservation and promoting sustainable cultivation practices among gardeners and commercial growers.
