Lycoris sanguinea f. albiflora - White-Flowered Orange Spider Lily

Thriving in the temperate regions of East Asia, Lycoris sanguinea f. albiflora stands out with its elegant, pale blossoms.

This botanical form differs from the typical species by producing white or creamy-white flowers rather than the characteristic orange-red ones.

Its unique growth habit is shared with other members of the genus. The foliage emerges in spring, dies back completely in summer, and is followed by naked flowering stalks in late summer.

Morphology

This deciduous perennial grows from a subterranean bulb. The globose bulb produces narrow, strap-like leaves in early spring that measure up to 30 centimeters in length.

During the late summer blooming period, a single erect scape arises, reaching a height of 30 to 45 centimeters. Each scape bears an umbel of 3 to 6 funnel-shaped flowers.

Flowers: Pale creamy-white to pure white tepals, with slightly recurved tips.
Stamens: Six stamens that are roughly equal in length to the tepals, unlike some other species in the genus.
Fruit: A three-valved capsule containing small, black seeds, though seed set is often low in wild populations.

Flowering season

Late summer, typically blooming in August.

Applications

Historically, the toxic bulbs were planted near rice paddies and gardens. The presence of these bulbs helped deter pests, mice, and moles from damaging agricultural fields.

In modern times, it is occasionally grown by collectors of rare geophytes. Its striking late-summer blooms provide unique ornamental value in woodland gardens.

Interesting facts

The specific epithet sanguinea refers to blood-red or orange coloration, making the form name albiflora (white-flowered) a literal contradiction.

Like many surprise lilies, it is known for blooming on completely bare stems, earning it various folk names associated with sudden emergence.
