About

Asarum canadense is a spreading perennial that remains low to the ground. In spring, it features downy, heart-shaped green leaves and produces purple-brown, cup-shaped flowers that are frequently obscured by the surrounding foliage.

About the genus

Asarum comprises either evergreen or deciduous perennials that develop a network of rhizomes, creating a dense layer of long-stemmed, heart- or kidney-shaped foliage. Some leaves exhibit a distinctive silver mottling. The flowers are unique, featuring a three-lobed calyx in muted, earthy tones. Commonly known as wild gingers, these plants are not related to culinary gingers; the name derives from the spicy fragrance of their rhizomes.
