Perennials For Zone 9
All garden plants will enhance the landscape.
There are several things that one may do to accomplish a beautiful landscaping result. One may modify the land itself or arrange and color code the structures in the area. Something as simple as using garden plants can create precisely the feeling that one needs or wants in any landscaping attempt.
Garden plants are an excellent choice when choosing a landscaping endeavor. Exotic plants are not a necessity and at times may be arduous to care for or pay. These plants are cheaper and at times a simpler alternative. Local foliage, whether low lying ground cover or flowers, presents a beautiful opportunity for landscapers. Any of the local plants, for instance, say Spanish lavender, grown in local conditions will give the landscaper less work regarding care and more regarding beauty.
If local is not what one looks for, then there are still several other plants that provide a more exotic feel to a landscape. Take, for instance, creeping rosemary which may be used in corners or in sure planters to give an overgrown feeling. If kept in good taste, then it will make the landscape stand out more and provide a stark contrast to the dwarf boxwood shrub used on the edge of the walkway.
Maybe a theme that is more oriented to coloring is the goal. These plants give anyone the opportunity to do that. One such technique is to have a high contrast planting style. In this manner, opposite colors that look well together (i.e., blue and orange) will create a dynamic and vibrant feel. Contrasting shapes, when using garden plants, will also provide a pleasant look to the garden. For example, a dwarf shrub hedged to be a round shape with a different plant, like a small agave plant or even sumac, gives a different feel and might inspire wonder and awe.
If you would like to use a plant that is more about looks with little to no maintenance, than the perennials known as ornamental grasses are an excellent choice. They are low maintenance, almost pest free, and above all, they look outstanding in any landscape attempt. Carex Evergold is one such plant that is perennial, deer resistant and loves the shade. It will work in the darkness oriented landscape. There are too many plants that could be used to achieve any desired look and combination. The only question that one must ask is which plants are wanted and how much time can be dedicated to caring for them. Envision the ideal landscape, and use these types of plants to achieve that vision.
