Few forms of plant life can create such an iconic floral display with so little effort as cacti. They are categorized as succulents because they have the ability to store water inside their bodies and use it during dry seasons. The best thing about cacti is that they can be displayed in myriad different ways.

In separate, decorative containers, floral arrangements, shared containers, sand terrariums, indoor window boxes, or even cans, small cups, or in outdoor gardens – they always create talking points. Cacti are indoor sun-loving plants that need perfect drainage and fast-draining cactus soil with the addition of sharp sand or grit. Water every ten days during the hottest part of the summer and cut off water in autumn to force dormancy. Most are toxic and not safe for children. Cacti come in a variety of shapes, sizes, textures, and colors and they all have a strong character. Here is a list of 64 gorgeous cactus plants to try cultivating in your indoor garden and tips on how to care for them.

TIP: Balance warm, cool and green tones and limit yourself to one color palette for a powerful statement.

How long do cactus flowers last?

Cactus flowers last only 1-3 days, but they are often gigantic compared to the size of the plants. Although they last that short, cactus flowers feature rich colors and simple, refined forms.

Does my cactus need sun?

Cacti usually need full to the bright sun with light shade in summer, so they won’t survive indoors without artificial grow lights. Desert species require the sunniest position whereas jungle and rain forest cacti dislike direct sunlight. All, however, need enough light essential for photosynthesis.

How to deal with spines?

Cactus spines can hurt and stick in the skin like a tiny fishhook. To be safe, display them away from activity areas and keep them out of the reach of children. Use gloves, a shirt with sleeves, and newspapers when repotting and inspecting cacti. Use sticky tape or white glue to peel the spines off the skin.

Why my cactus died?

Most probably because you overwatered it in winter. Inspect the roots and repot the plant immediately.

Conclusion

Related to succulents, cactus flower plants are colorful and fun to have in your indoor garden, especially for creating unusual displays.

Always ensure plenty of suns, even artificial lights, and light shade in summer, quality, and pest-free cactus compost or loam-based mix with grit. Water when the top 2 cm of the soil dries out and once a month in the autumn. Tolerant of dry indoor air. Don’t water in winter. Use a half-strength high-potash fertilizer in the growing season.
