Ailanthus altissima is an ornamental tree grown mainly for shade and also for its leaves which the silkworm feeds on. Sounds prettier when it is called by its unscientific name: "tree of heaven".
The acacia thrives in the wilderness of Paran (the location of several historic events in the Bible). Because it can flourish in a barren desert, Semitic tribesmen call it: "tree of life".
Frankly, every tree on the planet represents a heavenly gift from a Life-Giving Source. Trees are what make the earth inhabitable, and they should be shown respect. Not worship and adoration. Just respect.
The best ways to show appreciation for these marvelous creations is to plant, paint or photograph them. Being neither a talented photographer, artist or gardener, writing about them is my way of showing gratitude.
Having so many to choose from, the selection - the palm tree and the fig tree - was narrowed down based on two criteria: memories of my youth or plants that grow in a place that would be nice to visit.
