Lycoris flavescens var. uydoensis - Korean Pale Yellow Spider Lily

Thriving on the rocky coastlines of South Korea's Uido Island, Lycoris flavescens var. uydoensis captivates botanists with its rare pale yellow inflorescences. This bulbous perennial blooms in late summer, emerging rapidly from dormancy to produce naked flower stalks before the foliage appears.

As a localized variant within the Amaryllidaceae family, it plays a specific role in island ecology. Its survival is closely monitored due to its narrow geographic distribution.

Morphology

The subterranean structure consists of a globose bulb measuring up to 4 centimeters in diameter. Fleshy, strap-like leaves emerge in early spring, absorbing nutrients before completely dying back in the heat of mid-summer.

A stout, erect scape rises to a height of 50 to 60 centimeters during late August. The inflorescence forms an umbel containing 4 to 8 funnel-shaped, pale yellow flowers with slightly wavy tepals.

Applications

Pharmaceutical researchers study the plant for its active alkaloids, which may offer potential medicinal applications in the future. However, the presence of toxic compounds prevents any direct agricultural or domestic usage.

Interesting facts

This variety exhibits a unique life cycle common to the genus, where flowers and leaves never coexist. Locals refer to this phenomenon as a symbol of longing, as the green leaves never meet the bright blossoms.
