1. Landscape Plants This presentation is from Virginia Tech and has not been edited by the Georgia Curriculum Office.

2. Objectives • List & describe the 6 shapes of trees. • List & describe the 7 shapes of shrubs. • Describe the factors that are important in selecting trees or shrubs.

3. Types of Plants • Native – plants that are natural to the area • Exotic – Introduced to the area • Naturalized – were exotic but have adapted well to the area and now occur naturally

4. Trees • Act as the ceiling for the outdoor living room (yard). • Provide Shade

5. Selecting A Tree • Pay attention to: • Height of tree • How low the branches are to the ground • Density of foliage

6. Pay attention to: • Whether the tree is deciduous or evergreen • Seasonal color, foliage texture, flower and/or fruit bearing • Hardiness

7. Pay attention to: • Ease of transplanting • Resistance to Insects or disease

8. Types of Trees • Wide-oval • Vase-Shaped • Pyramidal • Round • Columnar • Weeping

9. Wide-oval • Much wider than tall • Often a small tree • Branches low to the ground • Works well to frame & screen • A focal point plant

10. Wide-oval

11. Vase-shaped • High, wide-spreading branches • Usually gives excellent shade • Allows human activity underneath • Make excellent street trees

12. Vase-shaped

13. Pyramidal • Shape is less noticeable as the trees mature • Accent plant • Large, high branching trees allow human activity beneath

14. Pyramidal

15. Round • Width & Height are nearly equal • Usually Dense • Lawn trees • Can be to create grove effects • If large, can be used to create heavy shade

16. Round

17. Columnar • Much taller than wide • Accent Plant • Frames views & structures • Useful in formal settings

18. Columnar

19. Weeping • Very Graceful • Attracts the eye (focal point) • Screens • Not useful if you want to use the lawn underneath the tree

20. Weeping

21. Weeping

22. Shrubs • Multistemmed • Used as the wall element

23. Selecting a Shrub • Pay attention to: • The silhouette of the shrub • Its branching structure • Size • Texture & Density • Color Contributions

24. Pay attention to: • Attraction to birds & other wildlife • Existing soil conditions • Hardiness • Resistance to attacks by insects & disease

25. Types of Shrubs • Globular • Low & Creeping • Spreading • Arching • Pyramidal • Upright & Loose • Columnar

26. Globular • As wide as is tall • Attracts attention • Accent plant • Use with a single pyramidal to create a strong eye attraction • Does not mass very well.

27. Globular

28. Low & Creeping • Low growing • Much wider than tall • Masses well • Use to edge sidewalks or cascade over walls • Controls erosion

29. Low & Creeping

30. Spreading • Wider than tall • Medium to large shrub • Masses well • Use at corners of buildings • Useful for screening, privacy & traffic control

31. Spreading

32. Arching • Wider than tall • Graceful • Softens corners • Background for flowers & statues • Provides screening

33. Arching

34. Pyramidal • Taller than wide • Attracts attention • Usually evergreen • Use to mark entries

35. Pyramidal

36. Upright & Loose • Taller than wide • Used for screening & framing • Used to soften buildings • Can closely space to create privacy

37. Upright & Loose

38. Columnar • Width about half of height • Flat topped & dense • Use for hedges if closely placed • Mass closely to create a solid wall

39. Columnar
