The Botanical Garden exchanges vegetative material with other such gardens as well as with other research institutes from around the world, through an international agreement that sets standards to protect biodiversity.

There is a seed catalogue, called the index seminum, of the various botanical gardens and through which orders are made. At the beginning of this year we received several requests for Arabian globe-cress (Globularia Arabica) seeds. This is a dwarf shrub belonging to the Plantaginaceae family, its flowers are blue and it flourishes on the kurkar hills of our Botanical Garden. The spherical form of its inflorescence is the source of its Latin name, which means “round head”.  The Arabian globe-cress is highly suitable for water-saving gardening, due to its long flowering period and its adaptation to arid habitats. As a result of the numerous requests for seeds, our hard-working volunteers collected multiple inflorescences throughout the summer. They are now cleaning and counting the seeds. Unfortunately, similar to previous findings in nature, we found that Arabian globe-cress has a very low ripening percentage, and despite the numerous inflorescences that were picked only a few seeds were obtained. This is an interesting subject for further examination, but for now it seems that the Arabian globe-cress seed requests must remain un-fulfilled.
