Family: Bignoniaceae
High Risk Traits:
- Thrives and spreads in regions with tropical climates
- Naturalized in Queensland, Australia (but no evidence in the Hawaiian Islands to date)
- Unconfirmed report that plant may be an allergen
- Tolerates many soil types
- Reproduces by seeds
- Self-compatible
- Fast growth rate
- Seeds dispersed by wind and through intentional cultivation
- Seeds may form a persistent seed bank (up to 4 years)
- Tolerates heavy grazing, mowing and fire
Low Risk Traits:
- Handroanthus chrysotrichus (golden trumpet tree, aipe) is a semi-evergreen/semi-deciduous (shedding foliage for a short period in late spring) tree from Brazil. It is commonly cultivated as both a street and garden tree and is particularly prized for its striking springtime display of vibrant golden-yellow to red flowers. These blossoms are not only visually captivating but also serve as a valuable source of nectar, making the tree beneficial for honey production. Additionally, its wood boasts exceptional density and resistance to decay so it is valued for its use in construction and carpentry. At this point in time, there are no reports of naturalization in Hawai'i.
- No reports of negative impacts where grown
- Unarmed (no spines, thorns, or burrs)
- Thrives in full sun and high light environments (dense shade may inhibit spread)
- Seeds lose viability after 150 days of storage (unlikely to form a persistent seed bank)
