The Okanagan Xeriscape Association

Welcome

You have just opened the door to a whole new way of looking at your landscape, whether that’s the yard around a house; the landscaping around your condo; the entrance to your business; or the welcome to a new home or subdivision you’ve built.

The Okanagan Xeriscape Association is a registered charity founded in 2009 to help people Garden with Nature, conserving water and energy in the process, but creating beauty.

By learning more about xeriscape, you are learning how to create colourful, attractive outdoor spaces while minimizing your use of water—a resource that’s in short supply in the arid Okanagan climate, as well as elsewhere.

That means you save money on water, but at the same time, when you employ xeriscape principles you also save money on pesticides because you’re growing plants that suit their natural environment so they are less vulnerable to insects and diseases.

We would love you to join us! Find out more.

Echeveria

Echeveria is a large genus of succulent perennials encompassing approximately 150 species. These perennials are native throughout Central and South America, extending north into Texas. They are particularly common in the southern and eastern Mexican states.

Here in the Okanagan Valley, Echeveria are considered tender perennials for they are hardy in zones 9-11 and will perish in our low winter temperatures. These succulents form rosettes of thick, fleshy, waxy leaves in colours ranging from pale green to icy blue and reddish-purple.

The popularity of these perennials has exploded in recent years with approximately a thousand cultivars currently available. The interesting forms and foliage of Echeveria make them an excellent choice for low-care succulent bowls and patio pots—easily able to flourish in the hot and dry conditions of our valley.

Beginning in Summer and continuing into Fall these succulents will produce star-shaped blooms in fiery shades of orange and pink. At the end of the season, these tender perennials can be brought inside and successfully overwintered in a bright area with indirect light.

As with many succulents, over-watering is the most common issue when growing these plants and can lead to root rot and plant failure. Whether planted outside or used as a houseplant, good drainage is essential for successfully growing Echeveria.

Choose a sharp-draining growing medium when potting up your succulent and ensure the plant is positioned slightly higher than the surrounding soil

If you are planning to take your Echeveria back outside in the Spring, be patient, waiting until temperatures are reliably above freezing and acclimatize them slowly to outdoor conditions.

Our Blog

Our new blog, On The Dry Side, is an opportunity to share information on how to garden with nature while conserving water in the Okanagan Valley.

As a group blog and forum, we welcome your contributions and comments and hope to create a blossoming community of xeriscape gardeners as well as a valuable archive of articles.

Trimming Ornamental Grasses

Trimming your ornamental grasses depends on whether they are Evergreen, Cool Season, or Warm Season varieties.

Seasonal Ornamental Grasses

An important distinction in the world of ornamental grasses is whether they are warm season, cool season, or evergreen.

Drip Irrigation Maintenance

A well maintained drip irrigation system is the most effective way of watering plants in the Okanagan. It distributes water directly to the root zone with the minimum evaporation waste.

Growing the UnH20 Garden

OXA has just completed the first phase of an expansion of the UnH2O Garden. The new garden area will illustrate drought-tolerant trees, shrubs and cedar hedge alternatives.

A good understanding of the composition and texture of your soil is key to successful xeriscape gardening

Garden Design

A well-designed landscape is a balance: of size, shape, colour and texture. Repeating groups of similar plants throughout the garden creates a sense of continuity and will be more pleasing to your eye.

Plan Your Garden

Whether planning a small condo patio or a large acreage, a renovation to an inherited space or the blank slate that comes with a new build, planning your garden is paramount.
