Plants require adequate amounts of several nutrients and elements, including sunshine and water. Plant varieties require varying amounts of water to maintain health and reproduce. Some plants require large amounts of water, while others require very little and retain water for long periods between watering and rainfall. Plants that grow naturally in arid areas exhibit water-retention capabilities. Many of the plants that hold water make nice houseplants or landscape species in areas with infrequent and minimal amounts of moisture.
Cactus plants lose very little water. These plants commonly grow in dry, arid locations with little competition from other varieties of plants. Naturally at home in the desert, cacti provide a source of moisture to area wildlife and rodents. These plants contain cells that soak up periodic moisture and hold it for long periods. The thick, outer skins help hold in moisture. Many types of cactus contain a waxy layer of skin. Because of their infrequent watering requirements, cacti make nice houseplants. However, the majority of cacti contain sharp, pokey spines, creating a possible danger in homes with curious pets and small children. Many types of cactus produce colorful, attractive blossoms that attract flying insects. Once pollinated, these blossoms produce small fruits. Interestingly, cactus plants do not grow natively outside of the Americas.
Native to southern Florida, the snowberry shrub produces leathery, thick leaves that retain water. This drought-resistant plant provides an attractive display of bright, white fruits that resemble the shape of coffee beans. This plant thrives in rich and fertile soil compositions. It prefers plenty of sunshine. The berries of the snowberry plant supply food for pigeons. These attractive shrubs grow as tall as 10 feet in some areas. The multi-branching habit of snowberry bushes resembles an evergreen vine.
Many individuals and gardeners call this a century plant, but the Havard agave blooms more often than once every hundred years, despite this popular misconception. It actually produces blossoms about once every 20 to 30 years. The flowers appear on tall stocks in the early summer on these occasions. This succulent plant's leaves direct rainfall downwards towards the center of the plant. It also makes the most of its water by storing it in its thick, pointed leaves.
