All plants need water to survive. However, like plants that require more water, some plants grow in a lack of water. They are the best drought tolerant plants and can live without water for a long time.
Agaves store water in their thick foliage and send their roots deep below the soil surface to collect the water available. The Leaf has sharp edges. Landscapers often use agaves due to the unusual shape of their foliage, and of course, they are low care and drought tolerant plants.
Bougainvillea is a champion in tolerating the drought. It seems to be one of the toughest shrubs that thrive on neglect in extreme and intense conditions. This colorful plant is easy to grow too.
Moss rose, or “Portulaca” is a drought-tolerant flowering plant that thrives in dry, poor soil. Due to its thick succulent leaves, it can survive for a long time without water. It comes in a variety of colors and requires warmth to thrive.
Lithops are unique stone like succulent plants due to the reason they are also known as “Living stones.” Lithops are suitable houseplants, with very low watering requirements they are easy to keep.

10. Rock Soapwort
Also known as “Tumbling Ted,” a good semi-evergreen groundcover that blooms in summer. It is native to the mountainous regions of the Southern Europe, it is relatively cold hardy and doesn’t grow well in hot climates (above zone 9).
