Egyptian Riverhemp Sesbania sesban

Egyptian Riverhemp is an introduced perennial tree, found in Hawaii, Puerto Rico, and the U.S. Virgin Islands.

⚠ Invasive here — plant a native instead USDA + GBIF

Egyptian Riverhemp 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.

Nitrogen fixer — Fixes atmospheric nitrogen through root-nodule bacteria — builds soil fertility for itself and its neighbours, cutting fertiliser need.Open guide →
Rain garden / bioswale — Rated FACW on the wetland list — tolerates wet feet, so it suits the soggy zone of a rain garden or bioswale that catches and filters runoff.Open guide →

Wildlife & pollinators

How pollinator value is scored →
❧ Caterpillar hosts ~6 caterpillar species

Sesbania supports ~6 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.

Recorded feeding on Sesbania in North America, including:

Anticarsia gemmatalis · owlet moth Colias eurytheme · Orange Sulphur Dichomeris acuminatus · twirler moth Ectomyelois ceratoniae · snout moth Erynnis funeralis · Funereal Duskywing Erynnis zarucco · Zarucco Duskywing

How we know this (1) Methods & honest limits
Photosynthesis Direct fact

A recorded categorical fact: each species is tagged C3 (standard), C4 (heat/water-efficient) or CAM (succulent, night-time CO₂ uptake) — or a facultative combination. We only show a trait card for the noteworthy C4/CAM cases; C3 is the unremarkable majority, kept in the data but not surfaced as a card.
