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.
Iris consist of 200 to 300 species that come in a variety of colors and bloom periods. Iris plants consist of both bulbous and rhizomatous perennials, many with sword-like leaves, with beardless or bearded flowers. Iris colors range from pastels and deep purples to shades of yellow and brown. They make excellent flowers for beds, borders and as mass plantings. The bulbs and rhizome varieties vary by bloom type and best time to lift and divide irises.
