Series 1: 4. Desert Worlds

Deserts are hostile - temperatures soar and water is rare. Yet plants find extraordinary ways to survive. They may grow imperceptibly slowly or travel the landscape looking for water. Others wait decades in suspended animation for rain to power an explosion of colour across the dunes.\n\nDesert plants protect their water stores from animals and from each other, using vicious spines, camouflage or by forging alliances with animals. Plants have invaded the most dangerous deserts on Earth, overcoming salt, fire and toxic bird droppings to bring life and colour to these harsh landscapes.
