Thousands of blue Heliophila flowers stand out against the barren valley walls in the Biedouw Valley.
Every spring vast swathes of land in the western parts of South Africa are transformed in a riot of colourful wildflowers. The explosion of colour over the otherwise dust-coloured landscape is one of the country's greatest natural displays. Superblooms, as they are known, occur in many deserts and arid landscapes around the world, but few are as consistent or diverse as South Africa's flower season.
The show lasts just a few short weeks, usually between late July and late September. With the first hot wind coming in off the Karoo desert to the east every one of these flowers in the Biedouw Valley will desiccate and die, their seeds lying dormant through the baking heat of summer until next year's rains.
