Curculigo
Curculigo capitulata
クルクリゴ
A perennial herb native to Southeast Asia, found wild in forests of the Ryukyu Islands and cultivated in greenhouses as an ornamental. Its striking clumping habit with large iris-like leaves is eye-catching. Classified near Arecales or Zingiberales, its phylogenetic placement remains debated even under the APG system.
Identification Points
- ✓Large linear to elliptical leaves in basal tufts
- ✓Parallel venation with plicate (folded) leaf blades
