Haku Sei Ryu Cast Iron Plant

Aspidistra sichuanensis 'Haku Sei Ryu'

The Story

Plant Bio

Aspidistra sichuanensis is a tough, rhizomatous, evergreen perennial that forms a clump of upright, leathery leaves. Native to the forests of Sichuan, China, it is prized for its ability to thrive in deep shade and less-than-ideal conditions. Small, fleshy, purplish flowers bloom at ground level in late winter or early spring.

The cultivar 'Haku Sei Ryu' is distinguished by its dramatic foliage. Each dark green, lance-shaped leaf features a prominent, central stripe of creamy white, which may be solid or speckled, resembling a dragon in flight, as its Japanese name 'White Dragon River' suggests.

Uses & Benefits:

Provides lush, evergreen foliage that brightens shady areas year-round.

Thrives in wet soils and poor drainage, reducing garden maintenance.

Supports native shade-dwelling insects and offers habitat cover.
