Selecting Plants for the Design : Selecting Plants for the Design Chapter 7 Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape The residential landscape is made of different elements. They are the plant materials and the physical structures. Physical structures in the landscape are patios, walls, fences, Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Plant Types: Trees Shrubs Groundcover Vines Annuals Perennials Ornamental Grasses Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Trees: can be defined as a single stem, woody, perennial plant reaching the height of 12 feet or more Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Shrubs: are multi-stem, woody plants that do not exceed 20 feet in height. In general shrubs are usually as tall as they are wide. They may be deciduous or evergreen Some examples of shrubs are: viburnums, honeysuckles, spireas, hollies, junipers and yews Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Ground cover: May be woody or herbaceous. It forms a mat less than 1 foot high covering the ground. Grasses is the most common plant used as a ground cover. Examples of other ground covers are: English ivy, periwinkle (vinca) euonymus , and Japanese spurge Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Vines: are woody or herbaceous (soft stemmed) plants that require some type of support. They may climb on objects or creep along the ground. Some examples of vines are: Boston ivy, wisteria, and clemtis Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Annuals: Are herbaceous plants that live for one growing season and are valued for the color of their flowers or ornamental foliage adds to the landscape. Common annuals are : Impatiens, marigolds, petunias, coleus, and zinnias Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Perennials: is a plant that has a life cycle of more than two growing seasons. They may be called woody as with trees and shrubs or herbaceous. Some popular perennials are: daylilies, peonies, lilies, and iris. Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape Ornamental Grasses: Are valued for their texture and colors that add interest to the landscape. Ornamental grasses can be annuals or perennials. Some grow best in warm climates while others prefer cool climates Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape What is plant nomenclature? it is the naming of the plants. All plants have two types of names: Common Name Botanical Name Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape What is the genius? it is closely related group of plants comprised of one or more species Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape What is a species? it is composed of plants that show characteristics that distinguish them from other groups in the genius Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape What is a variety: Is a group of plants within a species that show a significant difference from other plants in the species. Plants: Building Blocks of the Landscape : Plants: Building Blocks of the Landscape What is a cultivars? a plant with a distinguishing characteristic from other plants in the species but does not transfer that characteristic to it off spring through sexual reproduction Selecting Plants : Selecting Plants Trees: Are the largest and most permanent plant material used in landscaping Trees that are smaller and have a higher ornamental value are often called ornamental trees. Examples of ornamental trees are flowering dogwoods, flowering crabapples, redbud, and Japanese maple. Selecting Plants : Selecting Plants Trees: Hardiness refers to the ability of a tree to withstand cold temperatures . Trees have differing abilities to survive in areas in the United States. Selecting Plants : Selecting Plants Trees: choose resistant to disease and insect problems. If a tree has beautiful characteristics but is susceptible to insect infections and diseases, its value is reduced Selecting Plants : Selecting Plants Trees: They may also have a common problem involving the pH of the soil . pH is a measure of acidity and alkalinity of the soil pH scale ranges from a extremely acid reading of 1 to and extremely alkaline reading of 14 . A neutral reading is 7 . Most plants prefer a pH between 5.5 and 7.0 Selecting Plants : Selecting Plants Shrubs: Shrubs can have multiple functions in the landscape . The can be used as specimen plants, group plantings, hedges, screens, foundation plants, or shrub borders. Select shrubs on their intended use. Also consider their flowers, foliage, branching habits, and their suitability to the growing conditions Selecting Plants : Selecting Plants What is a Specimen Plant? it displays outstanding form, texture, and color. The plant can also stand alone Selecting Plants : Selecting Plants What is a group planting? consist of several different species of shrubs. They are considered a overlapping plant that will reach over plants to form a huge mass. Selecting Plants : Selecting Plants What is a Hedge? consist of all one type of shrub. The define space , they tie other landscapes elements together and they may screen views They can range from 20 feet to 1 foot high. They can be clipped for a formal appearance or unclipped for an informal natural look. Selecting Plants : Selecting Plants What is a Screen? is a solid mass of one type of shrub. It serves as a living wall that effectively blocks views. Selecting Plants : Selecting Plants What is a foundation plant? Are shrubs placed around the foundation of the house. They help tie the house to the landscape by softening the corners and they block the view of the foundation Selecting Plants : Selecting Plants What is a shrub border? A mass of many shrubs on the border of the property . They help create the outdoor living area, screen views, and serve as a backdrop for annual and perennial flowers Drawing Plants into your Plan : Drawing Plants into your Plan It is helpful to use symbols in your design work that represents the different types of plants. The symbols styles used vary from one designer to the other. Drawing Plants into your Plan : Drawing Plants into your Plan Here are some examples of plant symbols Deciduous Tree -- Ground Cover Evergreen Tree --Gravel Broadleaf Evergreen tree Deciduous shrubs Evergreen shrubs Deciduous Hedge Evergreen Hedge Broadleaf Evergreen Hedge Cobbles Drawing Plants into your Plan : Drawing Plants into your Plan Labeling: The most important thing after drawing in your plants is to label each one and to make sure to keep thing nice and neat to read. Lets Review!! : Lets Review!! The Design Steps!! Step 7 Locate Trees on the plan Step 8 Locate Shrubs Step 9 Assign textures and colors Step 10 Select plants to meet needs Step 11 Trace the plan on to quality vellum. Draw plant symbols on the good plan Step 12 Label everything Geometry for the Landscape : Geometry for the Landscape Objectives : Objectives By the end of this lesson you will be able to calculate: the perimeter of a given section of land the area of given section of land the volume of container Terms : Terms diameter (d)- the line that divides a circle into two equal parts radius ( r)- one half the diameter pi (?) - 3.14 or 22/7 height- line segment that shows how tall a triangle is. It is always drawn from a corner of the triangle to the opposite side forming a 90 degree angle. Terms continued : Terms continued perimeter(P)- the distance around the sum of all sides How much fence do you need to go around a yard? Circumference (C)- perimeter of a circle C= diameter X ? How much edging do you need to go around a flower bed? Terms Continued : Terms Continued volume (V)- how much fits in a given space Volume of a box= area of bottom X height Volume of a sphere+ 4/3 X pi X radius X radius X radius How much soil do you need to fill a flower pot? More Terms : More Terms area (A)- the space inside the perimeter rectangle= side X side triangle= (base X height)/2 circle= radius X radius X ? How many square feet of sod do you need to order to cover the yard? Example of perimeter : Example of perimeter 2 2 3 2 2 3 4 2+2+2+2=8 3+3+4=10 Examples of area rectangle : Examples of area rectangle 2 5 2 X 5 = 10 Examples of area circle : Examples of area circle 2 2 X 2 X 3.14= 12.56 Examples of Area of Triangle : Examples of Area of Triangle 8.2 8.9 6 A=(8X6)/2 A=48/2 A=24 8 Volume : Volume 7' 7' 9' Area of bottom=7'X7' Height=9' Volume=7'X7'X9' Volume=441 cubic feet Notes : Notes If a shape is not standard break it down into smaller standard shapes to make calculations Calculations must be done in the same unit of measurement (change feet to inches or vice versa as needed) Simplify all answers, do not write feet as decimals, convert to inches. Units : Units Perimeter- feet, inches, cm, m, mm, yards……. Area- sq. feet, sq. inches, sq. cm, sq. yards…... Volume- cubic feet, cubic inches, cubic cm, cubic yards……. Homework problems : Homework problems 1.How many cubic feet of mulch do you need to buy if you are mulching a 3 foot ring three inches deep around 4 trees that are 1 foot each in diameter? 2. How much soil is needed to fill 24 planters that are 1 ft wide, 6 feet long, and 1ft 6 inches deep? Slide 45: 3. Find the perimeter of the yard to the right. 4. How many sq. feet of sod would be needed to cover the yard at the right? 38’ 72’ Slide 46: 5. If three inches of snow had to be removed from a walk pictured below, how many cubic ft of snow would be removed? 50’ 46’ 12’ 8’ The End : The End Any Questions!!
