I used to be reluctant to have faux plants; the gardener in me thought they weren’t nearly as good as living plants. Also, the ones I liked usually cost more than I wanted to pay. But then I figured out that if I picked carefully (thin stems are key), I could cut some faux plants up, and they’d go further.
I’ve been mixing them with live plants lately; Kavi and Kevin totally thought my bougainvillea was blooming, but no. 
The leaves are alive, but the flowers are not. Surprise!
Also, I really like the little spiky pops of gold tucked in with my live ferns. Fun textural and color mix, and it lends a little autumn to the pots, and ties into the gold throw on the recliner (and the gold rug that you can’t see in that picture).
