Spreading Liverseed Grass Urochloa decumbens

Spreading Liverseed Grass is an introduced grass, found in Puerto Rico.

⚠ Invasive here — plant a native instead USDA + GBIF

Spreading Liverseed Grass is flagged invasive in the U.S. These natives fill a similar niche — same growth habit, bloom season, height, and region — so you keep the look and feed local wildlife instead of spreading a problem.

❧ Caterpillar hosts ~3 caterpillar species

Urochloa supports ~3 caterpillar species.

Native butterfly & moth caterpillars are the base of the terrestrial food web — most songbirds rear their young almost entirely on them. As a host for native Lepidoptera this is a modest genus.
