Did you know we grow sacred medicinal plants?

This article is only scratching the surface of indigenous knowledge and talks about four sacred plants of which CES actually grows two. Ask us for sage and sweetgrass or start chatting with Dawn about the wide variety of edible and medicinal plants we grow!


Job postings are now closed

We received over 150 applications for the summer assistant jobs (about 100 for the Native Plant Production Assistant alone) and were very excited about the potential so many candidates exhibited. We would like to thank all applicants for their interest in working with us and making Edmonton and Alberta a greener and better place to live. We wish you all a great summer!

Shinrin-yoku or forest therapy, has inspired a new industry in Edmonton

Journalist Madeleine Cummings tries to find out what distinguishes forest therapy from a walk in the woods. The article also explores what researchers have found out about the positive health effects such as improved self-regulation or lower blood pressure: http://www.edmontonexaminer.com/2017/11/22/a-japanese-health-movement

Native plants can help turn your yard into a nature preserve

We hope you all had a great Easter weekend! Here is another article about gardening with native plants. In it Missy Henriksen, vice president of public affairs for the American Association of Landscape Professionals points out that plants are actually proven to have mental health benefits, to reduce stress and improve attention and memory...

For the Love of Plants (Part 2)

Continuing from last week’s post about lichens, some of my favourite plants (and fruit!) are those in the Rose (Rosaceae) family.

Roses can be herbaceous plants (they don’t have persistent woody stems above ground), shrubs or trees. They have alternate leaves; simple or compound, and usually stipulate. The flowers are usually in racemes (an unbranched, elongated inflorescence with flowers maturing from the bottom upwards) or cymes (a flat or round topped inflorescence with lower pedicels longer than the upper).

Flowers in the rose family generally have all parts in multiples of 5, and many fruit we love to eat are found in the family (strawberries, peaches, plums, cherries, apples, pears, saskatoon berries, raspberries and blackberries to name a few!)

These three below are my favourite to eat... what about you?


For the Love of Plants (Part 1)

One plant group I love the most are Lichens. Lichens are technically NOT a plant, as they are only occurring thru a photosynthetic partnership between fungi and algae or cyanobacteria. Lichens don’t have a vascular system, and typically spread through spores or fragmentation. Lichens don’t have any organized leaf, root or stem structures; they are only equipped with hyphae and mycelium (which are the vegetative part of the fungus). Lichens grow in 6 different forms, including crusts, scales, leaves, clubs, shrubs, and hairs.

There are over 500 lichens species in Alberta’s forests, but my favourites are Cladina mitis (reindeer lichen) and Cladina stellaris (Northern reindeer lichen). They are very similar to each other, with key distinguishing features being their colour and shape. Reindeer lichen is pale yellowish green, and forms mats on ground, whereas Northern reindeer lichen is yellowish white, grows upright & reminds me of cauliflower.

We will continue with our love of plants posts all month long!

What Are Green Roofs?

Green roofs are a means of utilizing, typically, unused space by growing vegetation on building rooftops. Green roofs are a collection of materials, including vegetation, growing medium, drainage filter, etc. These can be extensive by retrofitting them on existing building roofs or intensive through practices of incorporating them into the design of new buildings. They have a range of applications including capturing excess stormwater, aesthetics, insulation, wildlife habitat, and local food production. Check out the City of Edmonton website for more information and where green roofs are already established in the city.



Bunchberry Meadows now open

The Nature Conservancy and Edmonton Land Trust made this happen. With the warming weather make sure you check out this place. It's a 250 hectare conservation area of native Parkland located just west of Edmonton.

2017 Highlights

Here are a few tidbits from last year's field season!

Shruti, our Sustainable Business Intern in Local Promotion, Marketing and Sales put together this booth for the Bloomin' Garden Show. Thanks so much for your help!

2017 was a final acceptance certification year for our ponds at Aurora-Walker Lakes. So we made sure everything looked the best it could be!

Next up was the Graydon Hill overflow pond. I wanted to make sure I snap a picture of the spring flooding before water disappeared later in the season.

Our 2nd final acceptance certification last year was at the Riverside SWMF in St. Albert. Only two years after construction completion, the site is progressing very well! I would say the life soil transfer was a huge success!

You might have also seen us at the downtown Edmonton and St. Albert farmers markets. I know I know, the hats are awesome!


Bare with me as I am trying edit this video. Apologies for blabbering in German. I was simply wishing Dan farewell ;)

Lastly, we planted a new site in Heritage valley in the fall. Hopefully Towne Centre will flourish next spring!
