A wide variety of plants grow naturally on the commons, bringing a changing environment with the seasons. Different habitats such as high oak woodland and the grassland plains support many common native species and rarer species such as wild orchids.

Bluebells, Hyacinthoides non-scripta, typically flower from April onwards and are a sure sign of spring. They can be found on the woodland floor and under hedgerows. Often, lots of bluebells are an indication of an ancient woodland, such as Bookham Commons.

Many different species of Wild Orchid can be found across the Commons. Considered a superstar in the wild flower world, Orchids appear in all shapes and colours. Dependent upon the weather, Orchids may flower from May to September.
