Q.Plants that play nicely with ZZ plants
I have 2 large planters in my office that currently have zz plants and mother tongue. I wanted to add more to each planter to fill some of the lower growing space. The planters are each 4′ long x 1′ wide x 1.5′ deep. Do you have any suggestions? One planter is positioned in front of a southern facing window and the other planter is not near direct light.
Thank you!

Philodendron or Pothos would make a nice addition to your planters.
