If you're a brown thumb looking for an easy plant to care for, you can't do much better than a snake plant. Snake plants can also be called mother-in-law's tongue and viper's bowstring hemp. These plants are native to West Africa and usually have stiff upright leaves and can vary in color. This hardy plant does great indoors and is adaptable to a wide range of growing conditions.
Plants naturally give off a natural toxin to protect itself against getting eaten. It is not uncommon for plants to have toxins on its leaves. A natural chemical process the plant goes through creates these metabolites to fend off animals or insects that may eat the plant.
For example, lemons give off a compound called Limonene which is fatal to moths. This, of course, doesn't harm humans at all.
Not all plants are safe to eat for humans though. Many of these houseplants can cause sickness if consumed. So we recommend keeping the houseplants out of your mouth.
For pet owners, toxicity is a major decision maker. Make sure your plant is nontoxic if you have pets. You can check the plant's toxicity level on the ASPCA's site.
Houseplants will often outgrow their pots. Once the roots start circling the container, it is most likely time to give your plant a new home. This will allow the plant to continue growing. If you want to keep the plant in the same container, it is good to take it out of the pot and trim the roots. When you put it back in its pot you should use fresh soil. This will help keep the plant healthier.
