Do you often feel that the moment you bring houseplants at home, they die no matter how much you efforts you put in! A lot of everyday houseplants evolve in dry regions and naturally learn to lock in moisture in their leaves, trunks, and roots, which means that they are completely fine even if you head out on vacation or simply forget about them for a few weeks.Snake Plant (Dracaena trifasciata)Snake plants are virtually indestructible. Their stiff, upright leaves act like water tanks, holding onto moisture for weeks at a time. Give them a deep soak every two to four weeks, and then completely leave them alone. If you’re going to kill one, it’ll be from watering it too much rather than too little—soggy soil causes their roots to rot fast.ZZ Plant (Zamioculcas zamiifolia)If you pull a ZZ plant out of its pot, you’ll see thick, potato-like tubers underneath the soil. These underground bulbs store water, allowing the plant to go three to four weeks without a drop. Combine that with its tolerance for dark corners and fluorescent office lights, and it’s easily one of the most forgiving plants you can own.Ponytail Palm (Beaucarnea recurvata)Despite the name, this isn’t a real palm tree—it’s actually part of the succulent family. Look at the bottom of the stem, and you’ll see a fat, rounded base. That swollen trunk exists purely to hold water during dry spells. Keep it in a bright spot, give it a drink every two or three weeks, and it’ll stay happy.Cast Iron Plant (Aspidistra elatior)Victorians loved this plant because it survived in dark, dusty, drafty homes, and it’s just as tough today. The dark leaves don’t push out much water through transpiration, so the soil stays damp for a long time. Water it once, let the dirt dry out completely, and you won’t need to worry about it again for another two to three weeks.Aloe VeraEveryone knows aloe for sunburns, but it’s also a classic desert succulent. Those thick, fleshy leaves are full of water-rich gel. Put it near a sunny window and let the potting soil dry out all the way to the bottom of the pot. In the summer, it might need water every couple of weeks. Come winter, when growth slows down, it can easily coast for a full month on its own.
