Boxwood

The presence of boxwood, which is easily recognisable from its small, stiff and oval leaves, is proof of an environment’s dryness. Its seed is capable of sprouting from a tiny crack, where there is almost no soil. Boxwood favours heat and humidity, like many other plants, but it can also withstand period of drought. For this purpose, it has a secret weapon: its leaves are covered with a thick and shiny skin and look as though they have been varnished. This feature limits perspiration and therefore water loss. In fact, it’s almost as though this species holds its breath during dry periods.
