Gad is another ordinary common noun in Hebrew. It means 'good luck'. We all want as much of it as we can get. So it is not surprising that it became a proper noun, the name of some people, a tribe of Israel, and a god. The god Gad was not ordinarily identified with Baal.
There currently are five recognized species in the Series Hexagonae, as the Louisiana iris group within the Genus Iris is called. They are: I. brevicaulis, I. fulva, I. hexagona, I. giganticaerulea and I. nelsonii.
The plant family of iris has 260 species that are divided into bulb types and rhizome types. Within the rhizome type are those classified as bearded, beardless and crested. The different types of iris flowers are well suited to a variety of growing conditions. The name iris refers to the Greek goddess Iris, who was named for the colors of the rainbow. Rhizome irises are an evergreen perennial, and bulb irises go dormant for part of the year.
