Keiki - literally means 'baby' or 'child' in Hawaiian. In horticulture, it is used to refer to a baby plant produced by the parent, usually in orchids, which is an exact clone of the parent plant.
Love the orchid keiki! When I first saw the small picture on the homepage, I thought it was a praying mantis sitting on a plant, lol. I learned that word when I was stationed in Honolulu for five years.
My spider plants make lots of keikis, too. That reminds me, I have to find a home for a couple of them that I potted up.
