North Florida Landscape Plants for Shaded Sites1
Frank Regulski, Jr. and David Marshall2Most areas of north Florida have environmental conditions which enable many ornamental plant species to thrive. These plants can normally be used by homeowner in a wide variety of locations or situations with little problem. However, a number of areas will have planting problems if plant selection is not done carefully. One of these problem areas is the shady site.
All plants need light to grow and develop. Light intensity and duration have a marked effect on plant and leaf size, color, shape, foliage density and amount of flowering. Some plants have certain requirements of light intensity and duration while others are tolerant of a wide range of light conditions.
Most plants can be categorized as requiring one of three levels of light — full sun, partial shade and full shade. These levels are based on the number of hours of sunlight the plant needs for proper growth and development. Full sun is normally considered to be sun exposure from 11:00 a.m. to 3:00 p.m., plants in partial shade would receive direct sun from 7:00 a.m. to 11:00 a.m., and plants in full shade would receive no direct sunlight. Most plants do very nicely in a partial shade situation. However, in full shade many plants develop a spindly, thin shape and will not flower normally. Not only does shade duration have to be considered but also shade intensity. A light shade would be provided by pines or other tall, high-canopied trees. Most plants will thrive under these conditions but if the shade is dense, special care in planting definitely should be exercised. In these situations plants should be selected which have adapted in nature to these shade combinations.
Occasionally, shade is combined with wet site conditions. In this situation a plant must be chosen which can cope with both conditions. Table 1 lists shrubs and trees are well adapted for shade or shade and wet sites in the north Florida landscape.
