Botanical Description

Lasiacis divaricata, commonly known as Bamboo Grass, is a native perennial grass with long, arching stems that often sprawl or climb through surrounding vegetation. It typically grows 3–13 feet (1–4 m) long, depending on support and habitat.

Growth Form
  • Loose, spreading grass
  • Arching or climbing stems
  • Often forms tangled patches in shaded areas
  • Flexible cane-like appearance
Its long stems can resemble miniature bamboo, which gives rise to the common name.
Stems
  • Slender, jointed, and smooth
  • Green to pale green
  • Branching at nodes
  • May lean or climb through nearby shrubs
Leaves
  • Long and narrow
  • Lance-shaped
  • 3–8 inches long
  • Smooth margins
  • Soft green texture
  • Alternate arrangement along stems
Leaves are broader than many open-field grasses.
Flowers / Seed Heads
  • Small branching inflorescences
  • Fine grass spikelets
  • Often delicate and not highly noticeable
Flowering structures are usually subtle compared to the foliage.

Habitat

Lasiacis divaricata belongs to Dry broadleaf evergreen forest (coppice) understory and the Woodland edges. 

Distribution 

The Bahamas, Caribbean, Central and South America.

Ecological Importance

  • Provides shelter for small insects and ground fauna

  • Helps stabilize shallow soils

  • Adds structure to forest understory


Cultural Notes

  • Often overlooked because it blends into surrounding vegetation

  • Named for its bamboo-like stems rather than true bamboo relation

Bamboo Grass is a native forest grass — subtle, adaptable, and well suited to Bahamian coppice understories.
