Houseplants You Can't Kill by Overwatering

2. Cyperus

Rather than a specific plant, consider buying any one of the 700 available species of Cyperus plants. These are mostly aquatic plants that can grow in still or slow-moving water up to 1.6-feet deep. Because there are so many species, you’ll definitely find one that suits your needs. Some are only a few inches tall, while others can reach well over seven feet. Umbrella Grass is the most popular Cyperus for homes because it is easy to care for and grows beautiful, long umbrella-like stems. While you may not want to water them as much in lower temperatures, they’re basically impossible to kill through overwatering throughout most of the year.
