About Yellow Trumpet Tree

Yellow Trumpet Tree (Handroanthus umbellatus) is a post-contact introduced tree documented on Kauaʻi through historical forestry planting records. The reviewed records do not establish present survival. Native to eastern and southern Brazil in tropical to subtropical seasonal forest and wet-ground woodland. A 1980 forestry ledger documents Kauaʻi planting within the 1910–1960 forestry program; no species-specific year is available from the reviewed index; it does not establish current survival, reproduction, or naturalization.

Kauaʻi evidence

Taxonomic identity, tree form, diagnostic morphology and island occurrence use the linked reviewed sources. Historical planting, cultivation, naturalization and invasive status are separate. Generated imagery is not occurrence evidence.

Kauaʻi occurrence and status

Kauaʻi occurrence: Recorded on Kauaʻi
Origin: Introduced
Conservation status: Not yet assessed
Evidence date: 2026-10-06
Evidence limits: Current survival on Kauaʻi, number of trees, occupied habitat, flowering or fruiting, recruitment, population trend, and ecological effects are all unconfirmed; no naturalization or invasive severity is inferred from the historical planting record.

Habitat and ecology

Habitats: Not yet assessed
Food and resource needs: Not yet assessed
Reproduction: Flowers require pollination, and the mature narrow capsules open to release flat winged seeds. Kauaʻi flowering, pollination, seed production, dispersal, viability and recruitment are unconfirmed.
Shelter: Not yet assessed
