50 Houseplants That Are Healthy to Keep at Home

23. Philodendron is a large family of plants with different shapes, sizes, and colors.

It’s challenging to have Philodendrons at only one entry on this list, as they encompass a truly massive family of hundreds of different colors, leaf shapes, growth habits, and colors. The heartleaf philodendron is a standard variety that looks quite similar to a pothos and has the same care requirements. Like the pink princess, some rare philodendrons can sell for as much as $200 and feature beautiful splashes of bubblegum on the leaves! Philodendrons, especially large-leaf varieties, are excellent oxygenators. There are philodendrons suited for almost any light situation and care needs, so this massive family is full of great purifiers.
