Antennaria dioica (L.) Gaertn.
Antennaria dioica is a perennial.
Antennaria dioica was already described and the name validly published by Carl Linnaeus. It was Joseph Gaertner, however, who reclassified it into todays valid botanical systematics .
The perennials reach heights of 2 to 5 centimetres and are comparatively slow-growing and short-lived. They have a erect habit, the main growing season is in spring and summer. The plants reach a width of 20 to 30 centimetres.
Antennaria dioica is evergreen. The mid-green, simple leaves are in rosettes. They are spatulate with entire margins. The surface of the leaves is pilose. The foliage is porous.
Flowers and Fruits
Antennaria dioica produces corymbs of white many-stellate flowers from May to June.
From spring to summer the perennials carry achenes.
The plants produce stolons which give rise to vegetative spread.
Antennaria dioica is native to the whole of Europe, the Caucasus, Turkey, Sibiria, Mongolia, northern Japan and Sakhalin.
The perennials prefer a sunny situation on moderately moist soil. They prefer gritty-loamy or sandy clay soil with a pH between 5,9 and 7,8. The plants need a soil depth of at least 30 centimetres for good growth. They tolerate temperatures down to -29Â°C (USDA zone 5) and need a frost-free period of at least 13 weeks.
Classification after Prof. Dr. Sieber
- open areas
Tolerance of special soil conditions
- none: anaerobic soil
- low: soil salinity
- medium: drought
The ornamental value of Antennaria dioica lies especially in the ornamental leaves. The recommended planting distance is 20 centimetres, the perennials are best planted in groups of 10 to 15. Suited for rockeries, roof greening and for beds and borders, as well as suited as cemetery plant, groundcover and as bee pasture.
Maintenance and Propagation
The plants need little to no maintenance if grown under suitable conditions.
- Cut back before seeds ripen to prevent self-seeding.
Propagate by sowing or by division.
