Lycoris radiata var. kazukoana - Red Spider Lily Variety

Growing wild in deciduous woodlands, Lycoris radiata var. kazukoana captivates observers with its intense red inflorescences that bloom on bare stems. This variety maintains a very specific ecological niche and unique chromosomal arrangement within the species complex.

It displays the classic hysteranthous behavior of the genus, producing leaves only after the flowers have faded. The striking crimson petals are highly visible to late-summer pollinators.

  • Tepals: Narrow, recurved, and reflexed backward, with moderately wavy margins.
  • Stamens: Long, slender, red filaments that curve upwards, extending twice the length of the perianth.

Applications

This variety serves as an important subject for cytological and evolutionary research due to its distinct cytotype. It is also grown in specialized collections focusing on preserving rare Asian bulb flora.

Interesting facts

Like the nominate variety of red spider lily, this plant contains lycorine, a toxic alkaloid that deters herbivores and pests. The sudden appearance of the red flowers from bare earth has inspired rich folklore throughout East Asia.
