Because cacti are usually slow-growing, you will likely need to buy a mature plant rather than grow it to size if you are looking to add a large cactus to your houseplant collection. Some cacti don’t reach maturity until they are 150 years old. Thus, a young cactus could easily outlive you before reaching the size you are looking for. For an eye-catching and dramatic impact, bring a bit of the desert into your home with these ten large cactus plants.
General Care
Surprisingly, cacti can be tricky plants to keep happy indoors - especially for those who are prone to ‘loving’ their houseplants too much (we’re looking at you, over-waterers!). Keep in mind that cacti are desert plants, and they can survive months (yes months!) without water if needed. It is always better to underwater a cactus than to overwater it. To thrive indoors, large cactus require at least six hours of direct sunlight every day which usually means a south-facing location. .
