Commissioned by President Nathan, Trees of the Istana features over 70 species of trees out of some 150 species found at the Istana. It provides readers with a glimpse into the greening of the Istana domain since its completion in 1869 and how it has been lovingly nurtured into a stately arboretum that has welcomed foreign dignitaries, statesmen, royalty, and local visitors. The Istana domain is also a flourishing sanctuary for wildlife including birds, butterflies, squirrels, dragonflies and more.

Some of the interesting trees featured in the book include an unusual nutmeg tree which has produced several fruits with 'twin' seeds instead of one seed, the Pride of Burma tree which produces beautiful orchid-like flowers, and Heritage trees that have grown into majestic giants.
