Flowers are always great decorations. A local florist can design beautiful arrangements for the shower. However, cut flowers from a florist can be quite costly. Consider buying potted plants from a local greenhouse and place them around the room. Fabric can be used to cover the pot and tied with ribbon to add extra flair. Small 4" plants could also be purchased and used as decorations. The guests could then take these home as shower favors. If you use cut flowers or larger potted plants, these could be given as door prizes.
