About Tree Daisy
Tree Daisy (Montanoa hibiscifolia) is an introduced tree documented on Kauaʻi by Bishop Museum’s 2025 checklist and the 2026 Smithsonian checklist. Its checklist classification is naturalized; current extent is unassessed. Native from Mexico through Central America and associated with wet-tropical vegetation, especially open and disturbed sites. Its tall woody growth and broad leaves can form dense cover where populations develop. Bishop Museum and Smithsonian document naturalized Kauaʻi occurrence, but current extent and impact are not quantified.
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.

Habitat and ecology
- Habitats
- Not yet assessed
- Food and resource needs
- Not yet assessed
- Reproduction
- Flower heads contain ray and disc florets and mature into small dry achenes without a pappus. Seed production, short-distance movement, and disturbed-site establishment are plausible requirements, but Kauaʻi-specific pollination, dispersal, and seed-bank behavior have not been studied.
- Shelter
- Not yet assessed
- Growth form
- Shrub or small tree
