Lycoris longituba var. flava - Yellow Long-Tube Spider Lily

Hailing from the moist, shaded mountain slopes of Jiangsu province in China, Lycoris longituba var. flava remains a rare botanical treasure. The variety distinguished itself by its vibrant yellow coloration, presenting a striking contrast to the typical white blooms of the species.

It occurs naturally in undisturbed forest understories where soil moisture is consistently high. Due to its restricted habitat preferences, it is seldom seen outside its native range.

Morphology

This plant produces a subterranean bulb that generates strap-shaped leaves during the cooler months of the year. During the summer dormancy, the leaves wither completely, clearing the path for the flower stalk.

The scape carries an umbel of yellow flowers characterized by their long perianth tubes. The tepals exhibit a clear yellow hue, lacking the red or pink stripes found in some other varieties.

Applications

Researchers study this variety to understand the genetic pathways responsible for yellow pigmentation in the genus. It is not currently cultivated for commercial or garden use due to its wild status.

Interesting facts

Botanical surveys indicate that this variety has not yet been successfully domesticated or artificially propagated on a large scale. Consequently, its wild populations represent the sole gene pool for this taxon.
