Echinocereus rigidissimus rubispinus aka Rainbow Cactus

Rainbow Cactus’s native range is Southeastern United States and Mexico.

Rainbow Cactus does best in dry soil and should only be watered sparingly.

To keep your Rainbow Cactus healthy, it's important to use a potting soil that won't retain too much moisture. A soil that drains well and contains perlite or vermiculite for drainage and some organic matter for nutrition is ideal. Adding a few handfuls of perlite to regular cactus soil from the store is an easy way to create this type of soil mix.

Rainbow Cactus requires abundant, bright, and direct light to thrive. The best placement for this plant is within one foot of a window to ensure it receives enough light. If you live in an area with more extreme weather, such as hot summers or cold winters, you may need to adjust the placement of the plant accordingly. During hot summer months, it is important to place the plant away from full sun, as this can cause the leaves to yellow or burn. During cold winter months, it is best to move the plant closer to the window to take advantage of the extra light that can help it survive. By keeping an eye on the current weather in your area, you can make sure your Rainbow Cactus is always in the right place to thrive.

Rainbow Cactus thrives in dry environments, but if you provide extra humidity or mist your plant, the lingering water on its leaves could create an ideal environment for certain fungal diseases.

The Rainbow Cactus is characterized by its slow growth and doesn't need fertilization in addition to its potting soil. By renewing the soil in its pot once a year, it should have enough nutrition. Remember, plants get their energy from sunlight, not from any fertilizers.
