Faux arrangements are fine if it works for you and you like them.

For years I had been making my own indoor arrangements with real orchids and bromeliads, but recently got tired of sourcing the right size/color plants and then re-potting my containers.

I found a nice faux orchid and bromeliad, and kept the real pothos in the arrangement. You have to get real close and touch the plants to see what is real or not.

Just be sure they don't get dusty.

If you select faux flowers that appear realistic they generally work in a space.

I have real plants that are dusty too, so it isn't just faux plants that collect dust!
