A lovely type of tree that gives great delight to children who toss handfuls of their large leaves in winter and play with their spinning helicopter seeds in summer.
Strictly speaking the terms shrub and bush are interchangeable. But being raised by an Englishman who liked gardening the term shrub for me has come to mean a small growing tree that has in some way been shaped and formed to have a manicured look about it. Whereas, a bush would, as the term suggests, be an unkempt shrub growing in a natural wild state and unfettered by mans intervention. Man interferes with the growth of bushes as a mechanism of control mainly for the following reasons: shade control, aesthetics, productivity, and encroachment. These things are very necessary, as who in their right mind would want a tree to block the morning sun from bathing their conservatory with warmth.
