Tropical Ash
Fraxinus uhdeiAlso known as Shamel Ash, Mexican Ash, Evergreen Ash
Tropical ash is a fast-growing, semi-evergreen canopy tree with glossy pinnate leaves that casts dense shade across warm temperate and subtropical regions. In its native Mexican cloud forests and river canyons, it anchors riparian soils, whereas in introduced island ecosystems like Hawaii, it forms dense stands that displace endemic understory flora. Wind disperses its abundant, single-winged samaras across great distances, allowing it to quickly colonize disturbed slopes and woodland clearings.

Responsible observation
- Foliage Inspection: Look for 5 to 9 lustrous leaflets arranged along each pinnate leaf stalk, often persisting throughout mild winters.
- Seed Tracking: Check ground litter in late summer and autumn for clusters of paddle-shaped, windborne samaras.
- Landscaping Awareness: Avoid planting near wild preserves in island ecosystems where seedlings easily escape and crowd out native flora.
