There are more reports of small Yellow Sanders trees on Little Cayman with fewer numbers on the Brac and Grand Cayman.

Thank you to Wallace Platts for his help and interest with this, as with all, native plants.

Yellow Sanders

Zanthoxylum flavum

Yellow Sanders can easily be mistaken for Mahogany at a distance, but closer up you can see that the leaves are covered with tiny, translucent yellow dots.

If you crush them they are strongly aromatic. The tree grows with a broad spreading crown in the open, but like many trees will develop a taller, thinner form in crowded woodlands.

On younger limbs the bark splits in irregular cracks along the branch: on the trunk it cracks more randomly and may shed a few woody flakes.

The trunk appears pale, with grey lichens. Yellow Sanders flowers in the early summer, with a mass of white blossoms which attracts swarms of bees.

This handsome tree is native throughout the West Indies, and also Bermuda and Florida. It grows on all three of the Cayman Islands, but is extremely rare.

It has beautiful wood and so has been seriously over-harvested throughout its range.

Very few individuals are known from Grand Cayman and efforts to propagate these trees and re-establish them in secure areas are under way.

Grow Cayman plants and encourage Cayman wildlife!
