Why some sedums can live in the driest spots

Some sedums have adapted to dry conditions by using crassulacean acid metabolism (CAM) photosynthesis.

Most plants lose water through stomates, tiny breathing pores on the leaves. These open during the day using a process called evapotranspiration.

But some sedums, and other plants like cacti, only open them at night, to conserve water.

Plants that are drought-resistant share similar traits, including thick succulent foliage, like the ‘jellybean’ sedums. SEDUMS FOR VERY DRY SPOTS:
