1. Selection and Use of Plants in the Landscape

2. Reasons for Choosing Plants Aesthetic appeal - attractiveness Function – a specific purpose in the landscape Adaptability – Their ability to adapt to a specific environmental type Management – How easy they are to grow and maintain

3. Sequence of Plant Selection 1.What function or purpose do I need this plant to fulfill? –Tree, shrub, or perennial? –Shade, screen, or erosion control? 2.What aesthetic qualities to I want the plant to have? –Shape, color, texture?

4. Sequence of Plant Selection, cont. 3.Which plant best suits the environment? –Sun or shade? –Wet or dry? –Sandy or loam soil? 4.Is it feasible for me to properly care and maintain this plant? –Pruning, fertilizing, watering?

5. Function Function is the purpose that the plant serves in the landscape Plants serve three major functions: –Architectural –Engineering –Environmental

6. Architectural Function Floors-direct the flow of traffic Walls-establish boundaries and set the mood Ceilings-contribute to openness or intimacy of a room Highlighting or masking architectural features Ceiling Wall Floor

7. Engineering Function Influence how we walk through the landscape Block objectionable views on or off the property Establish buffers between divergent activities Minimize drainage or erosion issues

8. Environmental Function The plants influence on the microclimate within the landscape “Microclimate” refers to temperature, wind, and light in a relatively small area Plants modify the microclimate and contribute to human comfort

9. Environmental Function, cont. Reduce heat loss in the winter Minimize heat gain in the summer

10. Environmental Function, cont. Plants can also be used as windbreaks to intercept and deflect prevailing winds and reduce wind speed in the protected area.

11. Aesthetic Function Most notable quality of a landscape Aesthetic preferences include: –Available space –Plant type –Form/shape –Ornamental characteristics of plant parts

12. Available Space Available space will determine the plant type and form/shape Height: maximum allowable height for the plant to attain Width: maximum diameter the plant can cover

13. Plant Type Tree: shade, ornamental/flowering, evergreen Shrub: broadleaf evergreen, deciduous Herbaceous perennial, ornamental grass, ground cover, vine, biennial, annual, or aquatic

14. Form/Shape

15. Characteristics Flower –Color –Time in bloom Foliage –Color: Seasonal display –Texture/density Fruit Stem/branches/bark: texture and color

16. Site Adaptability Site adaptability: relationship between the needs of the plant and the environmental and soil conditions on the property and/or the designated planting area.

17. Things to consider: USDA Hardiness Zone

18. Things to consider, cont: Soil Type –Sandy, Loam, Clay Soil pH Light Exposure –Full sun, partial sun, full shade Compass orientation or exposure –Prevailing winds and winter sun patterns Air pollution tolerance, heat tolerance, salt tolerance

19. Management Pruning –Minimal, seasonal, shearing Sanitation –Cleanup of leaves, fruit, stems/branches Irrigation –How much water is it going to need? Fertilization –How often will it need to be fertilized? Pest management –What pests does it attract and what is required to treat for these pests?

20. Summary Plant selection follows an organized process. The criteria used in the process integrate function, aesthetic preferences, adaptability of species to the site, and the management of the plant. Following these steps will result in the appropriate choice of plant and the plants success.
