Tanakaea

Tanakaea is a small genus of flowering plants in the family Saxifragaceae. It is native to Japan and Korea. The genus contains a single accepted species, Tanakaea radicans.

Tanakaea radicans, commonly called the Tanakaea Saxifrage, is a rhizomatous perennial herb. It is characterized by its basal rosettes of distinctive, dissected leaves. The leaves are usually palmate or pinnately lobed and have a leathery texture. The plant produces panicles of small, white, star-shaped flowers on reddish stems in the summer.

Tanakaea radicans is typically found in moist, shady habitats, such as forests and rocky slopes. It is sometimes cultivated as a groundcover in gardens, particularly in woodland settings. The plant prefers acidic, well-drained soil and partial to full shade. It is valued for its attractive foliage and delicate flowers.

The genus is named in honor of Japanese botanist, Yoshio Tanaka (1838-1916).
