How Saguaros Grow. Saguaros are a very slow growing cactus. In Saguaro National Park, studies indicate that a saguaro grows between 1 and 1.5 inches in the first eight years of its life. These tiny, young saguaros are very hard to find as they grow under the protection of a nurse tree, most often a palo verde, ironwood or mesquite tree.
A housing cooperative, or co-op, is a legal entity, usually a corporation, which owns real estate, consisting of one or more residential buildings; it is one type of housing tenure.
Cooperation is a word that refers to a process of working in unison, to achieve an objective rather than to work independently to compete with each other. We all know about cooperatives where people pool together resources to have a working system.
