The leaves of many desert plants have adapted to become spines. Growth must occur in short summer bursts lasting only a few days, a few weeks, or a month or two, depending upon such diverse factors as latitude, seasonal . It is the interplay of these factors during summer that determines whether temperatures are warm enough and moisture is sufficient to allow plants to grow.
