Welcome to the Xeriscape Garden - Penticton, Canada

1. 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 non-
indigenous 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

ornamental grasses and bulbs

17. D the Demonstration Garden
The 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.
