Ornamental Plants of Al Ain

Minimize

by Geoff Sanderson

The following is a list, prepared by Geoff Sanderson, of cultivated amenity horticulture plants.

The plants are nearly all found in general cultivation in Al Ain, very few are indigenous. It is not a complete list and the information is being continuously expanded as I find time to do some research. I have decided to pass it round in order to get some help and to provide something useful even in its present state.

A check list of indigenous species is being prepared by Marijcke Joengbloed accordingly I see little point in repeating the effort.

At this point in time this list should be used only as an incomplete reference and needs to be supplemented by illustrated texts.

The aim, in time, is to have illustrations for all of the plants listed and a more comprehensive description.

I would appreciate anyone photographing plants on the list, when they are in flower, and sending me the photo (with location and date thereon), via ENHG.

Any other information pertinent to any plant listed would also be welcome, especially origin, flowering time and any other habits or uses.

When it is eventually published, your name will be credited to the photo and to any text contributions.

Approximately 60% have been photographed to date.
