Textures:
An essential aspect of any garden to provide excitement and interest.
Some plants can provide multiple seasons of interest based on foliage and flowers.
Others are so unique that you will wait patiently for that one brief glimpse each year when they reveal themselves.
In a garden based on one color family, textures keep the movement and surprise one desires from any good garden design.
