One of my favorite Houzz photos is this one, in which the simplicity of tree trunks takes on new heights. The form of the trunks is repeated in the fireplace backdrop as well as the plants flanking the fireplace. Vertical stripes have even made their way onto the upholstery, enhancing the grand height of the space.Whether you are working with a large space like this or a tiny apartment dwelling, there are always ways to reflect the natural lines and forms around us. Conversely, consider bringing in plants to highlight the architecture of your space. Whichever way the inspiration flows, plants are your friend when you're designing, so don't forget to utilize them.
