Topiary - Trees like ivy, holly, bay tree, vines and many other evergreen trees can be properly sculpted and converted to decorative features into landscapes. This work of sculpting trees and crops are referred to as topiary. Topiary can be done not limited to gardens distributed over a sizable area but can also on indoor plants. Generally fine mesh or wires are used for topiary both indoors and outside. All that is required is a bit of imagination for topiary to be a great garden idea.
