Sustainable Design
•Designing for plant health and longevity;
•Creating “outdoor rooms”;
•Important in design regardless of size or cost.
Five Considerations of Sustainable Design
1. Functional
2. Maintainable
3. Environmentally sound
4. Cost effective
5. Visually pleasing
Site analysis
Client interview
–Activities in the landscape
–Timeline for installation
–Budget – install and maintenance
•Site survey
–Site inventory
–Specific, honest evaluation of site features; measurements
•Landscape Design Questionnaire, Site Evaluation Form
Design Principles
1. Unity
•A feeling of “oneness”
•Mix & match plants based on texture, form
•Repetition of hardscapes and plants
•All aspects should complement one another, not compete for attention;
•The entire design comes together to form one landscape.
2. Simplicity
•Large masses and groups
•Fewer individual species / cultivars
•Backgrounds, backdrops
•Color pallets
•1-3 focal points in a small space
•More important in commercial design than residential
3. Variety
•Variety in plants: type, form, texture, seasonal interest;
•Variety in hardscapes: color, texture
•Variety in location: areas viewed up close, entry gardens, decks, walkways, etc.
4. Balance
Formal vs. informal, symmetrical vs. asymmetrical
5. Emphasis
Integrate focal points, accent, and specimen plants in the landscape

2. 6. Sequence
The repetition of textures, colors, form and materials to transition the viewer through the landscape.
7. Scale
The relative size of one part of a landscape to another and to human beings using plants and hard features of
various sizes.
Plant Selection
•Select plants for sustainability
•Right plant, right place, right purpose
•Select plants based on their elements of design (characteristics)
• Plant type
• Select plants based on mature size
• Form
• Texture, Mix & Match
• Seasonal Interest
Color
•Warm: Focal point, draws attention
•Cool: Calm, relaxing, larger
•Neutral: Transitions, softens, expands
Design tips for small landscapes
1. Design elements to serve more than one purpose
2. Interplant ornamentals with edibles
3. Consider views
4. Use tall plants as backdrops
5. Design turf areas for maintenance
•Mowing – avoid tight radii
•Light & moisture requirements
•Repeated traffic, equipment
6. Avoid dividing the property
7. De-emphasize narrow areas
8. Locate details & variety close-up
