Perennials are easy to divide and share with other enthusiasts. Plot the blooming periods of the plants you choose on a linear calendar. This aides in developing continuous bloom and combining color combinations successfully. Large plants may be planted singly. Avoid planting in precise rows.
Informal shapes are easier to maintain than formal groupings.
Curved lines, varied plant heights, masses and textures result in a more natural appearance. Careful attention to foliage is important with perennials because few perennials bloom for more than a few weeks. Texture, form, height and color should be combined carefully. In addition to a linear calendar, plotting the garden to scale will ensure that these factors will be combined successfully. The bed in the following illustration was designed to provide continuous bloom from April to October.
