About
Asarum europaeum, known as asarabacca, European wild ginger, hazelwort, and wild spikenard, historically cabarick, is a species of flowering plant in the birthwort family Aristolochiaceae, native to parts of temperate Europe, and also cultivated in gardens. It is a creeping evergreen perennial with glossy green, kidney shaped leaves and solitary dull purple flowers hidden by the leaves. Though its roots have a ginger aroma, it is not closely related to the true culinary ginger Zingiber officinale. European wild ginger is sometimes harvested for use as a spice or a flavoring. In former days, it was used in snuff and also medicinally as an emetic and cathartic.
The FDA warns against consuming Asarum, as it is nephrotoxic and contains the potent carcinogen aristolochic acid.
How to grow it
A. europaeum is quite shade-tolerant and is often employed as groundcover where little else will grow. This plant has gained the Royal Horticultural Society's Award of Garden Merit.
Where it grows
Asarum europaeum has a wide distribution in Europe. It ranges from southern Finland and northern Russia south to southern France, Italy, the former Yugoslavia, and Bulgaria. It is absent from the British Isles and Scandinavia, and also from northwestern Germany and the Netherlands. Within Europe, the plant is grown outside of its range in the United Kingdom, Denmark, Sweden, Norway and the Netherlands.
