There are indeed cacti that can be found in rainforests. While it may seem counterintuitive to associate cacti with lush, tropical environments, there are actually several species of cacti that have adapted to thrive in the humid and rainy conditions of rainforests.
One such example is the Epiphyllum anguliger, commonly known as the Fishbone Cactus or Moon Cactus. This cactus is native to the rainforests of Mexico and Central America. Unlike the typical image of a cactus with spines or thorns, the Fishbone Cactus is actually a leafy succulent with long, flat and intricately shaped stems that resemble the bones of a fish. These stems grow in a cascading manner, making it an attractive hanging plant.
Another rainforest cactus is the Rhipsalis baccifera, or the Mistletoe Cactus. This cactus is native to the rainforests of Central and South America, as well as the Caribbean Islands. It is an epiphytic cactus, meaning it grows on other plants without harming them. The Mistletoe Cactus has long, trailing stems that hang down and produce small, round berries. It is a great addition to a tropical-themed garden or as a hanging plant indoors.
The Hatiora salicornioides, or Drunkard’s Dream, is another rainforest cactus that hails from Brazil. It has slender, cylindrical stems that grow in a dense, bushy manner. During the blooming season, the Drunkard’s Dream produces beautiful, bright orange flowers that add a burst of color to the rainforest understory. This cactus is also known for its ability to tolerate lower light conditions, making it suitable for indoor cultivation.
Now, you might be wondering how cacti can survive in rainforests where there is an abundance of water and humidity, which are typically not ideal conditions for desert-dwelling plants. Well, these rainforest cacti have developed certain adaptations that allow them to thrive in their unique environment.
One key adaptation is the lack or reduction of thorns or spines. In the rainforest, where there is less need for water conservation, cacti no longer require the protective spines to prevent water loss. Instead, these rainforest cacti have evolved to have smooth or slightly serrated stems, which allow them to collect and retain moisture more efficiently.
Additionally, rainforest cacti have adapted to grow as epiphytes, meaning they grow on other plants rather than in the ground. This allows them to take advantage of the higher light levels found in the rainforest canopy, as well as the organic matter and nutrients that accumulate in the crevices of trees. By growing on other plants, rainforest cacti can also avoid waterlogged soil that could lead to root rot.
In my personal experience, I have had the pleasure of growing a few rainforest cacti, including the Fishbone Cactus. I found that they are relatively easy to care for, as long as they are provided with the right conditions. They typically prefer bright, indirect light and well-draining soil to prevent waterlogging. It is also important to water them regularly, allowing the soil to dry out slightly between waterings.
To summarize, while it may seem surprising, there are indeed cacti that can be found in rainforests. These rainforest cacti have adapted to the humid and rainy conditions by developing smooth or slightly serrated stems and growing as epiphytes. They add a unique and unexpected touch to rainforest ecosystems, as well as tropical gardens and indoor plant collections.
