Inhabiting the shady, moist mountain slopes of eastern China, Lycoris longituba var. longituba stands out due to its impressive floral structures. The plants burst into bloom in mid-to-late summer, producing large clusters of white or cream-colored flowers on sturdy, leafless stems.
This particular variety is highly valued in botanical collections for its distinct morphology. It represents one of the evolutionary links within the genus Lycoris in East Asia.
The ovoid bulb gives rise to long, linear leaves that mature in winter and spring before senescing in summer. The flowering scape reaches up to 60 to 80 centimeters in height, bearing an umbel of 5 to 7 large, fragrant blossoms.
Each flower is characterized by a perianth tube measuring up to 5 centimeters in length, which is significantly longer than in other species. The tepals are broad, white or cream-colored, and only slightly reflexed at the tips.
Mid-to-late summer
Scientific investigations focus on extracting galanthamine and other alkaloids from the bulbs for neurological research. Culturally, it serves as an ornamental subject in botanical gardens specializing in East Asian flora.
The name longituba highlights the unusually long perianth tube of the flower. This feature attracts specific long-tongued nocturnal pollinators, such as sphinx moths, to ensure successful fertilization.
