Members of the genus are perennial, biennial, or annual herbaceous plants and are characterised by their succulent leaves and stems. Some species are grown in greenhouses for their unusual foliage and sometimes showy flowers. Low-growing species are popular in rock gardens and rock walls and as edging in garden borders.
- One common adaptation in many succulents is the timing of the opening of their stomata, which are small mouthlike structures on the surface of plant leaves and stems. Stomata allow for the uptake of carbon dioxide from the environment and the loss of water and oxygen to the environment.
- Sedums can survive in space: Sedums are highly favoured for living roofs and green building designs because they can withstand extreme temperature fluctuations, harsh winds, and very little soil.

After the blooming season, the dried flower heads remain beautiful through the winter. You can even cut them, place them in a dry vase, and they will hold their shape indefinitely as dried decor.
