50 Houseplants That Are Healthy to Keep at Home

4. Dumb Canes, or Dieffenbachia, are flowering tropical plants ideal for cleaning xylene and toluene from the air.

These bushy plants can grow up to six feet tall and flourish in almost any environment. Each plant features yellow leaves near the vein and turns a dark green toward the edge of the leaf, creating a unique ribbon and spots pattern on each leaf. Though Dumb Canes can produce flowers, the flowers are not impressive and create a toxic sap. Additionally, the plant is extremely toxic to cats and dogs and should be kept out of their reach at all times.
