Tall Albizia Albizia procera

Tall Albizia is an introduced perennial tree, found in the lower 48 states and Puerto Rico. It grows to 82 ft.

More about this plant

Albizia procera, commonly known as white siris or karoi tree, is a species of large tree found natively in southeast Asia and India. It is most commonly found in open forests, but may also be found on the margins of rain forests and in monsoon and gallery forests. It is considered an invasive species in South Africa. Wikipedia →

⚠ Invasive here — plant a native instead USDA + GBIF

Tall Albizia 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 ~5 caterpillar species

Albizia supports ~5 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 for introduced plants — native genera typically support far more.

Recorded feeding on Albizia in North America, including:

Anacamptodes fragilaria · geometer (inchworm) moth Anypsipyla univitella · snout moth Ascalapha odorata · Black Witch Automeris io · giant silk moth Chlorostrymon maesites · Amethyst Hairstreak Homadaula anisocentra · Mimosa Webworm Moth

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.
