Cactus close-up

Enjoy a rare look at the Garden's expansive cacti and succulent collection as hundreds of specimens seldom displayed for public view are presented in the Linnean House conservatory for a limited time!

Arid and semi-arid regions account for a third of the earth's surface and contain some of the world's most important hotspots of plant diversity. The plants that thrive in these regions show an array of fascinating adaptations to the harsh environments in which they grow. Plants of the arid regions exist at the extreme limits of tolerance of environmental conditions; therefore the slightest change to the environment can result in the loss of plant diversity, making them one of the most at-risk ecosystems in the world.
