Introduction to Cactus:
Cacti are the desert plants famous for their ability to survive in dry/arid environments. These are native to the Americas and due to evolving for millions of years, they have adapted with thick stems for water storage, spines for protection from predators, and CAM photosynthesis to minimize water loss.
Cacti represent desert symbols as well as extremely popular house plants all over the globe due to their many shapes, colors, and beautiful blooms across different species.
From giants such as Saguaro to stones like Lithops, each cactus has its own unique story on survival against all odds with stunning flower displays.
Let’s learn more about these plants in this comprehensive article.
History and Origins of Cactus
Cacti are ancient plants that have undergone many changes over millions of years. According to fossil records, they were already found in the Americas during the late Miocene epoch, approximately 25 million years ago.
The cactus family, Cactaceae, is believed to have originated during the Eocene-Oligocene transition, around 35–30 million years ago, though some older sources suggest an even earlier origin during the Late Cretaceous period.
Most researchers agree that cacti first emerged in South America, gradually dispersing to Central and North America, as well as the islands of the Western Hemisphere. This major lineage of succulent plants is now recognized for its remarkable diversity and adaptation to arid environments.

Growing Cactus Indoor vs. Outdoor
| Category | Indoors | Outdoors |
|---|---|---|
| Light Requirements | Cacti like bright, indirect light. A sunny windowsill or a room with a lot of natural light works best. | They love full sunlight. Outdoor cacti need direct sun for several hours every day. |
| Watering | Water less often because the inside is more controlled. Make sure the soil dries out completely before the next watering. | Outdoor cacti can handle rain, but during dry times, you might need to water them sometimes. |
| Temperature | Cacti do best in room temperatures but keep them far from cold drafts or super hot spots indoors. | Outdoor cacti enjoy warmer weather, but some can survive chilly nights, depending on their type. |
| Pests | Indoor cacti can get pests like spider mites and mealybugs. It’s important to check them regularly. | Outdoor cacti may attract pests like scale insects or aphids, but natural predators help control them. |
| Soil and Drainage | Use cactus-specific soil that drains well in pots with holes at the bottom to avoid too much water. | Outdoor cacti like sandy, well-draining soil and often do great in rocky, dry areas. |
