Common questions
What is the most neglect-tolerant houseplant?
The ZZ plant (Zamioculcas) and the snake plant (Sansevieria) are the standout choices. The ZZ plant stores water in thick rhizomes and the snake plant in its thick leaves. Both cope with low light and can go two to three weeks between waterings in summer. Both are on this list.
How long can these plants go without water?
Use the watering interval on each card as the starting point. ZZ plant and Snake plant wait the longest. Pothos, Peace lily, Parlor palm, Lucky bamboo, and Chinese evergreen still need checking about weekly in summer.
Can I leave these plants alone when I go on vacation?
For a trip longer than about a week, arrange for someone to check the plants. ZZ plant and Snake plant can usually wait longer than the others, but heat, light, and pot size change how quickly the mix dries.
