garden - City of Penticton
WELCOME TO garden Xeriscape refers to landscaping with water conservation in mind. It can be achieved by incorporating seven basic principles. By adopting these techniques you can create an attractive, diverse and sustainable landscape that uses less water. The City of Penticton Xeriscape Garden displays many plants and plant combinations to inspire you, and includes many plants indigenous to the Okanagan’s dry climate. It is comprised of three distinct planting areas of similar water usage, designated in the plan by three distinct colour codes. The Demonstration Garden provides examples of how indigenous and nonindigenous drought-tolerant plants can be combined to create a water-wise landscape on a typical urban property. Explore the Xeriscape Garden and refer to this guide for: • Seven Principles of Xeriscape • a descriptive list of 40 Top Plants • the Xeriscape Garden planting plan • complete plant list including perennials, shrubs and trees, ornamental grasses and bulbs Okanagan Lake Eckha rd t Main ore Lakesh inster Westm a Way Marin The Xeriscape Garden is located in Marina Way Park, east of the Penticton Art Gallery. The garden was planted in 2007. *Xeri (rhymes with terra) is from the Greek word “xeros”, for dry. table of contents Planting plan........................................................................ 1 How to use this map............................................................. 1 Seven Principles of Xeriscape........................................... 2 - 5 40 Top Plants......................................................................... 6 40 Top Plants, continued....................................................... 7 40 Top Plants, continued....................................................... 8 40 Top Plants, continued....................................................... 9 Perennials, list.................................................................... 10 Ornamental grasses, list..................................................... 10 Shrubs and trees, list.......................................................... 11 Planting plan: A.................................................................. 12 Planting plan: B.................................................................. 13 Planting plan: C.................................................................. 14 Planting plan: D, Demonstration Garden............................ 15 The central area ‘C’ focusses on, but is not entirely devoted to indigenous plantings. How to use this map This Garden is comprised of three distinct planting areas of similar water use/irrigation as follows: ■ very low ■ low ■ low to moderate, designated by three distinct colour codes. All plants are identified with both botanical and common name, and cross-referenced by location. Use the number codes to locate each plant on the plan. 1 The Seven Principles of Xeriscape... Xeriscape Xeri (rhymes with terra) is from the Greek word ”xeros” for “dry”. right plant, right place plan 1 planning & design A well designed plan involves assessing and assigning space for function, privacy and navigation. Consider sun and wind exposure, drainage, sightlines, topography, existing trees and shrubs, utilities (both overhead and underground), soil conditions and local bylaws. Commit your plan to paper. 2 plant selection Select plants with low water needs. Local indigenous plants are inherently ‘engineered’ for low water use, and offer a familiar and varied habitat for wildlife. Choose the right plant for the right place, appropriate to your garden‘s soil, micro climate, sun exposure, and drainage. Consider each plant’s mature size. Group plants of similar water needs together. 2 soil turf the foundation of your landscape 3 analysis & preparation 4 Soils are the foundation of your landscape. They should be healthy, rich in organics, deep, and well-drained. Soils should be analyzed and amended as required prior to planting. practical turf areas Your landscape may include turf of a practical size. Turf areas should be functional and of appropriate sizes for the planned use. Use drought-tolerant grass species (like fescues) that require less water. The Seven Principles continued ... 3 wise water use organic mulch 5 efficient irrigation 6 A well designed and maintained irrigation system, combined with an appropriate watering program will reduce water consumption. organic mulch Organic mulches applied and maintained at appropriate depths assist in moisture retention, soil fertility, weed suppression and prevention of soil erosion. The Seven Principles continued ... 4 nurture & maintain 7 good maintenance Dedication to proper landscape and irrigation maintenance will enhance your landscape and provide water conservation. The Seven Principles continued ... 5 40 Top Plants 40 plant profiles have been documented for their distinctive presence in this Garden. Representing a broad spectrum of reliable performers, their colour, form and textures provide a palette to guide and inspire you in your plantings. Smart choices for water-wise gardening, you can depend on them to be readily available in local nurseries. As a bonus, your selections of indigenous plant selections will enhance and support our valley ecosystems.

provide examples of how indigenous and non-indigenous drought-tolerant plants can be combined to create a water-wise landscape on a typical urban property. The garden to the left (D1) has no lawn, and uses a gravel path between the planted areas. The garden to the right (D2) includes a small lawn of EnviroTurf TM, a mix of drought-tolerant species that form a turf-like surface. In both gardens, plants are chosen and placed to provide features of privacy, year-round interest, and a variety of size, shape, texture, and colour. location Botanical name • common Name location Botanical name • common Name D1 D2 D3 D4 D5 D6 D7 D8 D9 D11 D12 D13 D14 D15 D16 D17 D18 D19 D20 D21 D26 D27 D29 D34 D35 D36 D39 D40 D41 D42 D43 D44 D45 D46 D47 D48 D49 D50 D52 D53 D54 D55 D56 D59 D61 D62 D63 D64 D66 D67 D69 D72 D73 Juniperus scopulorum ‘Blue Haven’ • Blue Haven Juniper Mahonia aquifolium • Oregon Grape Amelanchier x grandiflora ‘Autumn Brilliance’ • Saskatoon Ribes cereum • Wax Currant Lavandula angustifolia ‘Munstead’ • Munstead English Lavender Achillea tomentosa ‘Moonshine’ • Moonshine Yarrow Philadelphus lewisii • Lewis’ Mock Orange Syringa patula ‘Miss Kim’ • Miss Kim Lilac Syringa ‘Tinkerbelle’ • Tinkerbelle Dwarf Lilac Sedum spectabile ‘Brilliant’ • Brilliant Sedum Liatris spicata ‘Kobold’ • Kobold Blazing Star Lamium • Creeping Lamium Alyssum montanum ‘Mountain Gold’ • Mountain Gold Alyssum Penstemon fruticosus • Shrubby Penstemon Lonicera maximowiczii var. sachalinensis • Sakhalin Honeysuckle Miscanthus sinensis var. purpurascens • Flame Grass Juniperus sabina ‘Moor-Dense’ • Moor-Dense Juniper Arctostaphylos uva-ursi • Kinnikinnick Iris germanica ‘Loop de Loop’ • Bearded Iris Chrysothamnus nauseosus • Common Rabbit-brush Perovskia filigran • Russian Sage Panicum virgatum • Red Switch Grass Hemerocallis • Daylily Penstemon pseudospectabilis • Desert Penstemon Yucca glauca • Soapweed Spiraea japonica ‘Goldmound’ • Goldmound Spirea Chasmanthium latifolium • Northern Sea Oats Schizachyrum scoparium • Little Bluestem Rosa glauca • Red Leaf Rose Viburnum plicatum ‘Summer Snowflake’ • Summer Snowflake Viburnum Aster novi-belgii • Michaelmas Daisy Buddleia davidii • Butterfly Bush Calamagrostis x acutiflora ‘Overdam’ • Variegated Reed Grass Miscanthus sinensis var. purpurascens • Flame Grass Hemerocallis • Daylily Lavandula angustifolia ‘Munstead’ • Munstead English Lavender Santolina chamaecyparissus var. nana • Dwarf Lavender Cotton Potentilla fruticosa ‘Sunset’ • Sunset Potentilla Juniperus scopulorum ‘Blue Haven’ • Blue Haven Juniper Sesleria heufleriana • Blue-green Moor Grass Heuchera ‘Mint Frost’ • Mint Frost Coral Bells Koelreuteria paniculata • Goldenrain Tree Geranium sanguineum ‘Striatum’ • Blood-red Cranesbill Pennisetum alopecuroides ‘Hameln’ • Fountain Grass Penstemon pseudospectabilis • Desert Penstemon Rosa x rugosa ‘Therese Bugnet’ • Therese Bugnet Rose Artemisia x ‘Powis Castle’ • Powis Castle Artemisia Pinus mugo ‘Mughus’ • Mugo Pine Miscanthus sinensis var. purpurascens • Flame Grass Pinus mugo ‘Pumilio’ • Dwarf Mugo Pine Sedum • Showy Stonecrop Helictotrichon sempervirens • Blue Oat Grass Yucca glauca • Soapweed water use/irrigation: low to moderate 15
