Description

Arthropodium cirratum is a perennial herb that grows from a rhizome. It typically reaches a height of 60-90 cm. The leaves are broad, strap-like, and can grow up to 1 meter long. The plant produces a flowering stem that bears clusters of small, star-shaped white flowers with a slight fragrance. The flowers bloom in late spring to early summer.

Habitat

This species is commonly found in coastal and lowland forests, often growing on rocky outcrops and cliffs. It thrives in well-drained soil and can tolerate a range of light conditions from full sun to partial shade.

Cultural Significance

Propagation

The plant can be propagated by dividing the rhizomes or from seed. Division is typically done in early spring or autumn, while seeds are sown in spring.
