Choose your living plants. These are the ones you will have to take more time to care for and will be the base to the rest of your decorations. Any local garden center will be able to help you choose ones that go with your plan of decorating with live plants and artificial arrangements and match your lifestyle as well.
Pick out your faux flowers. They are available in many different materials, including old-fashioned plastic, silk and even wax. Depending on the style you are going for, you are sure to find ones in your color choice and design style.
Pick out your containers. These will truly bring your personal taste into the room so take your time. Baskets are great for country decor, simple glass vases and pots work for contemporary, and flowered cut crystal in all shapes and sizes are available for Victorian or other elegant styles.
Buy florist foam and other supplies that you need to create the pieces you will be using to decorate with live plants and artificial arrangements. In addition to foam, which will hold all of your faux stems in place, there are other realistic choices that you can purchase. There are even gel kits that, when mixed and poured into vases, turn into realistic-looking water.
Put it all together. Arrange the faux flowers in different ways until you get the look you want. Try varying things by mixing and matching a few of the fake stems in the pots with your living greens.
Add your creations around the rooms of your home. As with any interior design project, group your creations into cohesive settings, matching colors and/or textures to keep the space flowing. When decorating with live plants and artificial arrangements, find the balance between the two by alternating what is living and what isn't.
