You may have seen from my past posts I'm not what you would call an avid gardener! I do, however, love flowers and up until a few years ago would buy a fresh bunch of pink lilies every two weeks - just replacing the old bunch. They were pretty inexpensive at the time but these days I've moved towards flowers of a "fake" kind. It's much more cost-effective and needs zero maintenance. They are widely available at quite a few different price ranges.
Michael's has a variety, as does Ikea, but it's worth shopping around to get the type you want. I found it tough to get really good pink lilies (and there is simply no way to replicate the gorgeous fragrance), but I did find white ones for a reasonable cost. I got a vase as a housewarming present about ten years ago, and it has been used for many long-stem bouquets - real and fake!
Another good place to check out is Winners/Homesense. They had a pretty extensive selection of little potted "plants":
Ikea had some pretty good ideas on display too. I really liked these hanging pots. They would look great in a gazebo or pergola. You don't need to worry about them getting too much/not enough sun or making sure they're topped up with water. I'm all about the simple things in life!
Put your fake plants in a cute little pot and personalize!
