Summary
Cephalanthera longibracteata, commonly known as Swordleaf Helleborine or Long Bracted Helleborine, is a deciduous herbaceous plant native to a variety of woodland habitats, including deciduous and mixed forests, often on calcareous soils throughout Asia. It typically grows to a height of 1.5-2 feet (0.46-0.6 meters) and is characterized by its sword-shaped leaves and elongated inflorescence bearing white, showy flowers that bloom in late spring to early summer. The flowers are notable for their size and the long bracts that extend beyond the blooms.
Swordleaf Helleborine is appreciated for its elegant flowers and is used in shaded garden settings, such as woodland gardens and naturalized areas. It is relatively low-maintenance, requiring minimal care once established in the right conditions. It prefers part shade, thriving under the dappled light of larger trees, and does well in medium or fast-draining clay or loam soils with a neutral to alkaline pH. While it needs consistent moisture, it is important to avoid waterlogged conditions. This species is not commonly found in the nursery trade but can be a unique addition to a shade garden for those who can source it. It is, however, susceptible to root rot if drainage is inadequate and may be difficult to establish due to its specific soil and light requirements.CC BY-SA 4.0
