Lycoris flavescens: Reddish-Yellow Surprise Lily Guide

Boasting pale yellow blossoms that illuminate East Asian temperate zones, this bulbous perennial holds a special place in regional floras. Lycoris flavescens, widely known as the reddish-yellow surprise lily, is found in the wild across Taiwan and South Korea.

This taxon arose as a natural hybrid between Lycoris koreana and Lycoris sanguinea. Its genetic makeup contributes to its unique coloration, distinguishing it from other red or white spider lilies in the region.

Morphology

As a herbaceous geophyte, this plant possesses a subterranean bulb that enables it to survive seasonal dormancy. The strap-like leaves appear in the spring or autumn and die back before the reproductive phase begins.

Morphological characteristics include:

  • Flowers: Medium-sized tepals featuring a soft yellow to pale reddish-yellow hue.
  • Inflorescence: An umbel-like cluster supported by a singular, erect scape.
  • Tepals: Recurved margins that create a delicate, spider-like silhouette.

Interesting facts

Botanists have identified this plant as a triploid sterile hybrid, meaning it does not produce viable seeds and propagates primarily through bulb division. The synonym Lycoris chejuensis refers to specimens found on Jeju Island, South Korea.
