The Okanagan Xeriscape Association
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.

Did you know that the 2nd largest use of water in the Okanagan is used on our household lawns & gardens?
Here’s a reminder to check out the Make Water Work website to make your pledge to reduce water waste. Xeriscape is a very effective way to make water work.
Plant of the Month
Hibiscus syriacus, commonly known as Rose of Sharon, is continuing to put on a show in the Xeriscape demonstration garden.
This deciduous, multi-stemmed shrub produces blooms similar in appearance to hollyhocks in shades of white, pink, and bluey purple with some bi-colors and doubles available.
The shrubs in the garden are only a few years old but will ultimately reach a height and width of up to 10-12 feet. Rose of Sharon starts blooming as early as June and is still in bloom in the garden now in October.
Native from India to China, these shrubs are tolerant of drought, heat, poor soil, and deer. They are easily grown in zones 5-9 when sited in full to part-sun either as a specimen or mass planted. I suggest using the new columnar cultivars, the Pillar series, as an alternative to cedar hedges, as this cultivar has a fastigiate, meaning tall and narrow growth form, reaching heights of 10-16 feet but with a spread of only 2-3 feet.
The blooms are appealing to pollinators, especially butterflies and hummingbirds, and the bloom colors available contrast nicely with the predominantly warm fall colors currently on display. Hibiscus syriacus suffers few disease or pest problems.
Tip of the Month
Deadheading, deadheading, deadheading.
You can greatly increase the bloom time of both your annuals and perennials by removing spent flowers from your plants.
As the flowers fade, simply pinch, cut or shear the fading blooms. Regular deadheading forces the plants to focus on flower production rather than producing seeds.
If left too long, deadheading can sometimes seem like an overwhelming chore, so I suggest regular deadheading throughout the season. You will be rewarded with a fresh flush of flowers late into the season.
Right now Nepeta, Centranthus, Yarrow, Shastas, and Salvia are all putting on a second show in the Xeriscape demonstration garden.
