 Flower color is another important feature of both the herbaceous border and the mixed border that includes shrubs as well as herbaceous plants.Flower gardens are sometimes tied in function to other kinds of gardens, like knot gardens or herb gardens, many herbs also having decorative function, and some decorative flowers being edible.A simpler alternative to the designed flower garden is the "wildflower" seed mix, with assortments of seeds which will create a bed that contains flowers of various blooming seasons, so that some portion of them should always be in bloom.
