    Camellias at a Glance (CIR461/EP002)

    April 23rd, 2012
    Topic(s):Lawn & Garden

    Figure 1. Camellia flowerNative to Asia, the first camellia plants were brought to America in 1797 and grown in New England greenhouses. Over the last 200 years, they have proven to be dependable additions to the southern landscape, where they grow and bloom with minimal care in most inland areas of North and Central Florida. Camellias are long lived and function well as foundation plantings, screens, accent plants, background groupings, and hedges. Camellias flower in the fall and winter when few other plants are blooming. For the remainder of the year, their glossy, evergreen foliage, interesting forms and textures, relatively slow growth, and low maintenance make camellias excellent landscape plants worthy of more use. This 6-page fact sheet was written by Sydney Park Brown, and published by the UF Department of Environmental Horticulture, April 2012.

    Identification of Poison Ivy, Poison Oak, Poison Sumac, and Poisonwood (ENH886/EP220)

    April 2nd, 2012
    Topic(s):Ecosystems & Species, Health & Nutrition, Lawn & Garden

    Figure 2. Poison ivy leaves (consisting of three leaflets) and flowersFlorida parks and woodlands are favorite places for many people who enjoy outdoor activities. Unfortunately, the native plants poison ivy, poison oak, poison sumac, and poisonwood can make these outings a miserable experience. All four contain urushiol, a plant oil that can cause a severe skin rash (dermatitis) when any part of the plant is contacted. Allergic reaction can occur directly by touching the plant or indirectly by coming into contact with the oil on animals, tools, clothes, shoes, or other items. Even the smoke from burning plants contains oil particles that can be inhaled and cause lung irritation. This 6-page fact sheet helps individuals learn to identify these plants in order to avoid contact with them. Children should be taught to recognize these plants, particularly poison ivy, as it is by far the most common.

    Landscape Design: Drawing a Planting Plan (ENH1195/EP456)

    February 10th, 2012
    Topic(s):Lawn & Garden

    Figure 10. All plants are labeled by the total count and plant name.Selecting and placing plants in the landscape is the art and science of arranging plant material to make a healthy, functional, and beautiful yard. The mix of science and art is expressed in the guiding principle of “right plant, right place,” meaning to select plants that can thrive in the growing conditions of the site and locating them for both visual appeal and health. Selecting and arranging plants are the last steps in the overall design process after the site analysis is complete and the activity areas located and designed.Developing the planting plan is a sequential process, but it is important to remember that the process is not completely linear; sometimes decisions about plant material require reworking previous steps in the sequence and making adjustments to the plan. This 10-page fact sheet was written by Gail Hansen, and published by the UF Department of Environmental Horticulture, January 2012.
