All of the advise about silk plants has been top shelf. Personally, I have never liked the look of plastic plants in any tank. Mine or the tanks of my friends. One thing to keep in mind, is that when you purchase your silk plants, make sure they are of good quality,(i.e. no wires or metal in the stems, the silk is colorfast -meaning no heavy leaching of color dye, and all of the plant is there-no missing leaves, etc.). Take time to examine your silk plants. There's a wide variety out there. Happy shopping and stay away from local fish shops. Michaels or a dollar stores are good places to check for bargains. Good luck.
