Todays Objectives

• Describe the functional roles of plants in the
  landscape.
• Discuss the functional uses of plants in the
  landscape.
• Correctly identify and discuss the roles of each
  plant in the landscape located outside of the
  building.
• Individually observe your yard at home and make
  notes of the plants located there and the role
  that they play. You will present your findings
  to the class tomorrow!

3
Functional Roles of Plants

• Structural Framework
• Screening
• Enclosing
• Framing
• Integration

4
What is Structural Framework?

• The way the yard is laid out.
• Dividing larger spaces into smaller spaces.
• Will direct viewer through the design.

5
How Do Plants Screen?

• Block unattractive views.
• Consider line of sight to be screened.
• Screens observed from a distance-taller longer.
• Denser in areas where people walk by at slower
  speeds.

6

8
How Do Plants Integrate the Landscape?

• Unify the landscape and tie it together.
• Blend the house and other structures into the
