Botanical description
Rohdea japonica is a rhizomatous, evergreen perennial herb in the Asparagaceae family. It features thick, lance-shaped, dark green leaves that arise from a short, stout rhizome. The leaves are typically 10-20 inches long and 2-4 inches wide. Small, inconspicuous flowers appear in late winter or early spring, borne on a short spike. These are followed by bright red berries that persist through the winter. The plant typically grows to a height of 12-18 inches. It prefers shaded locations and well-drained soil.
Companion planting
Rohdea japonica thrives in shaded conditions and pairs well with other shade-loving plants such as hostas, ferns, and camellias. It can be used as a ground cover under trees and shrubs. Avoid planting in areas with full sun or overly dry conditions.
Propagation methods
Rohdea japonica can be propagated by division of the rhizomes in spring or fall. Seeds can also be used, but germination can be slow and uneven. Offsets that develop around the base of the mother plant can also be carefully separated and replanted.
History and traditions
Rohdea japonica has a long history in East Asia, particularly in Japan and China, where it is cultivated for its ornamental value and perceived spiritual significance. In Japan, it is often grown in pots and displayed in tokonoma alcoves, considered a symbol of good fortune and longevity. It is also used in traditional medicine for treating various ailments.
