Many cactus plants are grown as houseplants - it's not because they are so drought tolerant and can put up with neglect, lack of water, and overcrowding. The desert looks like a dry and inhospitable place, until about a week after a heavy rainfall. Then, suddenly, buds explode into action, and flowers of all shapes and sizes open to attract insects to pollinate them, a rare event, and one that they take every advantage of. #floweringcactus #cactus #drygardening
