Cacti flowers have at least 10 petals, with the sepals combined with the petals, and have numerous stamens surrounding a multi-lobed stigma. Generally, cactus flowers are short-lived and provide the primary characteristics that separate cacti from other succulents. And remember, keep cactus plants away from pets and small children to prevent injury.All cacti have flowers. Take note: Always source your cacti from responsible nurseries and never from the wild.

Types of Cactus You Can Grow at Home-Even Indoors When growing desert cacti indoors, the New York Botanical Garden recommends placing them in the sunniest spot in your house, rotating pots regularly to preserve the plants' shape, adding artificial light if needed, and reducing fall and winter watering to “only enough to keep the plant from shriveling.” Tropical types are a bit different, but don’t worry-you’ll find links to care instructions for the tropical species on our list. Many types of cactus plants also adapt well to houseplant life, including those featured here. Our cactus garden tips will answer all your questions on soil, containers, watering, and overwintering indoors. In the garden, cacti are best cultivated in containers, unless you live in a climate similar to their native habitat. Types of cactus run the gamut from desert natives, such as the tall tree-like saguaro (its pronged silhouette is iconic of the Sonoran Desert of the American southwest and Mexico) and the cute-as-a-button star cactus (it looks a bit like a flowering sea urchin), to tropical types, like the Christmas cactus (did you know this beloved holiday bloomer originated in the forests of Brazil?). Areoles are responsible for sprouting cacti's signature spines, flowers, branches, and leaves, enabling cactus species to take on thousands of captivating forms. Unlike other succulents (and all other plants, for that matter), members of the Cactaceae family have areoles, little bumps on the outside of the plant that possess some pretty cool capabilities. As succulents, meaning they store water in their stem or foliage, cacti are built for drought tolerance, but that's not all that makes them special. When it comes to low-maintenance plants, it doesn’t get more extreme than cacti.
