Since the pistachio plant may have two trunks and it may grow bushy and broad, it usually grows in an open habitat. Under optimal conditions the pistachio tree may live and reproduce for hundreds of years. Pistachios are flowering trees that have brownish green flowers without pedals. When the time is right, usually at the start of summer, the flowers produce fruit. The fruit grows in clusters that are parallel to grapes. This fruit has become known as a nut but it is actually a drupe which is simply the edible part of a seed. This fruit is usually red or green in color and is enclosed in a tough shell. The greener the nut is, the  better it is suppose to taste.
