Welcome to the Xeriscape Garden - Penticton, Canada

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 non-indigenous drought-tolerant plants can be combined to create a water-wise landscape on a typical urban property.

How to use this map

TheSevenPrinciplesofXeriscape...

planning 1 & designA 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.

XeriscapeXeri (rhymes with terra) is from the Greek word ”xeros” for “dry”.

right plant, right place

plant 2 selectionSelect plants with low water needs. Localindigenous 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.

the Demonstration GardenThe two plantings forming the far east sections of the Xeriscape Gardens were designed to 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.
