Flower gardening is the horticulturist's reward for hard work. Flowers and flower borders provide color against the predominant green of a landscape. They are the accent and contrast that make a landscape lively and interesting. Flowers also complement most of the features that conventional landscaping materials, such as trees and shrubs, establish. They can add depth and dimension, form and texture, and change heights and slopes, besides their most obvious asset which is color. Flowers can also be useful, providing culinary herbs for the table and cut flowers for arrangements.
