1 Garden Design Diana Alfuth, Horticulture Educator UW-Extension, Pierce County Designing Gardens as Part of a Sustainable Landscape

2 Sustainable Landscape Design Functional Maintainable Environmentally Friendly Cost Effective Visually Pleasing

3 Consider the function of each portion of the landscape Note problems/attributes in the existing landscape Evaluate the site characteristics, including soil type, pH, light, wind, etc. Decide on your goal and landscape style Sustainable Landscape Design

4 Garden Design Formal = straight lines, plants in rows, symmetrical, globes and columns Informal = curvilinear patterns, plants in intertwined masses, asymmetrical, natural plant forms Garden Design

5 Sustainable Landscape Design Locate gardens as part of your overall landscape design Create a good turf area, with functional spaces and gardens behind the concept lines that form the turf shape

6 Garden Design Consider each individual viewpoint when designing the gardens and planting beds

7 Sustainable Landscape Design The most beautiful landscapes are “designed”, not decorated. They create unity by incorporating Principles of Design, including:

8 BALANCE

9 SCALE

10 REPETITION

11 SEQUENCE

12 SIMPLICITY

13 VARIETY

14 Design beds to keep maintenance to a minimum Garden Design

18 What makes it look good? Human eyes need a place to start: FOCAL POINT A focal point is the first thing we see when we look at a landscape. Sustainable Landscape Design

19 Examples of things that create focal points are: Artwork A plant that is different than those around it Structures Birdbaths, birdhouses, birdfeeders Boulders Bare spots Diseased/dying plants Debris FOCAL POINTS CAN CHANGE THROUGHOUT THE SEASONS! Sustainable Landscape Design

20 Focal Point

21 Focal point Sustainable Landscape Design

22 Locating Focal Points Any given view of the landscape should have one major focal point, and maybe one or two secondary focal points. Too many focal points creates a “busy” landscape. Locate focal points 1/3 of the way from one side. Sustainable Landscape Design

23 Focal Point?? Sustainable Landscape Design

24 After our eyes find a focal point, they need to go somewhere, and look for lines to follow. Lines can be formed by edging, paths, structures, plant masses, plant form, shadows, etc. Sustainable Landscape Design

25 Focal point Sustainable Landscape Design

26 Lines

27 Sustainable Landscape Design Lines

28 Sustainable Landscape Design Lines

29 Sustainable Landscape Design Lines

30 Too many lines, or no lines, create a confusing, busy landscape. Lines should take the eye where you want it to go—and keep it in the landscape. Avoid lines that take the eye into the sky, or into the neighbor’s yard! Sustainable Landscape Design

31 Before you start thinking about specific plant species, to get a good design, you must first plan for each plant’s characteristics, or “Elements of Design”

32 Elements of Design Primary (visual) Plant type Plant form Plant height/width Plant Texture Plant Season of Interest (including color) Sustainable Landscape Design

33 Plant Form: Arching Upright Creeping/spreading Drooping/weeping Mounded Horizontal branching Columnar Sustainable Landscape Design Consider both foliage form and flower form

34 Plant Size (height and width) Consider the plant’s MATURE, NATURAL size! Sustainable Landscape Design

35 Plant texture Visual coarseness/fineness of foliage, branching, flowers. A plant’s texture is relative to what’s around it, and it may change throughout the season. Plant texture is EXTREMELY important in design, and can make or break a landscape Sustainable Landscape Design

36 Texture Sustainable Landscape Design

37 Texture

38 Sustainable Landscape Design Texture

39 The finer the texture, the more of it you need. Lawn grass is our finest textured plant. Consider textural changes to create a focal point, repetition, and variety. Sustainable Landscape Design

41 Season of Interest This is how you get a landscape that is interesting all year—by planning it out on paper! For each plant, group or mass, think about when it will have significant interest, and make that work with what’s around it, creating focal points, repetition, unity. Sustainable Landscape Design

42 Season of Interest

43 COLOR!COLOR! What’s the easiest way to choose a color scheme? STEAL AND COPY ONE!!!! Sustainable Landscape Design

44 Color

45 Sustainable Landscape Design Color * Warm colors appear closer, so are good for viewing from a distance. * Cool colors recede, so are better up close.

50 Elements of Design Secondary:Soil/fertility preferences (non-visual) Moisture requirements Light requirements Hardiness Disease & Insect resistance Sustainable Landscape Design

51 On a scale drawing, locate plants in slightly intertwined groups and masses, using single plants only when a focal point is desired. These groups and masses will help move the eye through the landscape. Sustainable Landscape Design

52 Next, keeping in mind the Principles of Design (Balance, Scale, Variety, Emphasis, Simplicity, Sequence, Repetition), assign Elements of Design characteristics to each plant, plant group or plant mass. Sustainable Landscape Design

53 “Key” plants soften a hard feature in the landscape On vertical corners or structures, they break the visual vertical line and keeps the eye in the landscape They soften large areas of hard surface, such as retaining walls or fences Sustainable Landscape Design

54

55 “Accent” plants are a focal point— they draw attention to themselves Could be all year, or only certain times, such as when in bloom Accent plants can be a single plant, a group, or a mass Sustainable Landscape Design

56

57 Plant “groups” are 3 or more of a species, where each individual plant is discernable Often serve as accent plants at some point during the year Sustainable Landscape Design

58

59 “Mass” plants – when many plants of a particular species are planted close enough together so that you can’t see the individual plants Masses serve to move the eye between more important components and to tie a landscape together Sustainable Landscape Design

61 Start with a backdrop! Everything looks better with a backdrop! Create one if one doesn’t exist yet. Then, locate any non-plant focal points. Then, start with your biggest plant or your focal point plants. Using your available space as a guideline, your tallest plant should be 1/3 or 2/3 the height of the backdrop (unless the backdrop is more than feet tall). Sustainable Landscape Design

62

63 How big should your garden be? The width of a border planting should be 1/3 the width of the total area. Each “height” should have an equal amount of space within the bed. Flower Garden Design

64 In small areas where other rules don’t apply, a 4-8 foot wide border allows for an attractive variety of plants. Sustainable Landscape Design

65 For island beds, be sure they fit into the overall concept plan. A good standard size is 8 feet wide, 15 feet long, with maximum plant height of 5 feet, but it should be in scale to the site! The tallest plant should be as tall as ½ the width of the bed. Sustainable Landscape Design

66 For beds viewed from a distance, hold your hands out in front of you at shoulder width. Where your hands meet the backdrop is a good length for your flower bed. Garden Design

69 Know what plants look like all year

70 Intertwine plant groups to avoid lines that act as inadvertent focal points

71 Deciduous shrub, 2 ½ ’ X 5’, creeping, medium texture, spring interest Deciduous shrub, 6’ X6’, upright, medium texture, fall interest Evergreen shrub, 4” X 4’, mounded, coarse texture, winter interest Herbaceous perennial, 18” tall, mounded, fine texture, summer interest (red flowers) Ornamental grass, 40” tall, upright, medium texture, fall interest Sustainable Landscape Design

72 Finally, choose specific plant species that match the assigned characteristics for each plant, group or mass. Sustainable Landscape Design

73 MATCHING PLANTS Emerald Elf Amur Maple Regent Serviceberry Glossy Black Chokecherry Spreading Cotoneaster Beach Plum Compact American Cranberrybush Emerald Triumph Viburnum Diablo Ninebark Sustainable Landscape Design Deciduous shrub, 6’ X6’, upright, medium texture, fall interest

74 MATCHING PLANTS Birdsnest Spruce Dwarf Norway Spruce Dwarf Balsam Fir Aglo Rhododendron Dwarf Yew Evergreen shrub, 4” X 4’, mounded, coarse texture, winter interest Sustainable Landscape Design

75 MATCHING PLANTS Rosy Glow Barberry Evita Weigela Snowmound Spirea Fritschiana Spirea Cutleaf Stephenandra Sustainable Landscape Design Deciduous shrub, 2 ½ ’ X 5’, creeping, medium texture, spring interest

76 MATCHING PLANTS Big Bluestem Red Switchgrass Overdam Feather Reed Grass Red Flame Grass Tufted Hairgrass Fountain Grass Windspiel Purple Moorgrass Strawberries & Cream Ribbon Grass Sustainable Landscape Design Ornamental grass, 40” tall, upright, medium texture, fall interest
