Thurs, June 8, 7:00pm: Paul Spriggs on Favourites for the Crevice Garden

Part of a crevice garden in the Calgary area.
This hybrid (in-person plus Zoom) meeting will feature Paul Spriggs of Victoria, who is well known to CRAGS as a passionate and knowledgeable rock gardener. Paul will discuss some of his favourite plants for crevice gardens. Learn how the crevice environment is ideal for many alpine plants.
Paul Spriggs has been rock gardening for over 23 years and building crevice gardens for about 17 years. He is an avid plant explorer, photographer, mountaineer, owner of Spriggs Gardens Landscaping company, and past President of the Vancouver Island Rock and Alpine Garden Society. He has a passion for all wild plants especially those of dwarf stature and collects and cultivates them at various gardens in his hometown of Victoria, BC, Canada. Paul has learned the craft of crevice garden building directly from one of its innovators, Zdenek Zvolanek, of the Czech republic, and in the past decade and a half, has built many gardens in public parks and private homes that range in size from small feature troughs, to large installations involving many tonnes of stone. Paul is passionate about spreading the word of this style, through speaking to garden clubs all over the west, and by giving workshops for those keen on learning the finer points of this developing art form.
Paul and co-author Kenton Seth of Colorado published the first North American book on Crevice gardening, The Crevice Garden (Filbert Press, 2022)
The meeting will be held at Lakeview Community Hall for those who wish to meet in person. Members will be also be sent the Zoom link prior to the meeting. The talk will be recorded and made available to members for one week.

ial construction, bringing the multi-beneficial nature-based strategy to the roof.
Come learn about the basics including what green roofs are, what they do, their design considerations and how they help solve the most pressing ecological and developmental issues facing our communities. Cold-climate case studies from nearby and abroad will be presented and discussed to highlight the beauty and benefits of adding more vegetation to the built environment. Green roofs can offer new opportunities to use alpine plants, and Kerry will discuss suitable plants for rooftops.
In 2000, Kerry Ross began working on one of the first buildings in Alberta to integrate contemporary green roof systems into the building’s design. Bison Courtyard, the project situated in the town of Banff, spurred her passion to learn more about green roof technology as an innovative method to lessen the impacts that buildings have on the natural environment. This experience, along with study and field research led her to become one of the first Green Roof Professionals in Canada. In 2010, she launched Green T Design, a company dedicated to green roof design, installations and maintenance. Kerry remains a local champion of incorporating green roofs where possible.
Friday April 14, 2023 at 7:00pm: Nick Courtens, Alpines in the Betty Ford Alpine Gardens
At this hybrid meeting we will hear from NIck Courtens about the extensive rock gardens near Vail Colorado.

Nick Courtens
Nestled in the ski town of Vail, Colorado at 8,200 ft, Betty Ford Alpine Gardens is home to many alpine and rock garden plants from North America and beyond. Curator of Plant Collections, Nick Courtens, invites you on an exclusive tour of the various rock gardens that have been built throughout the past 30 years including several crevice gardens, trough gardens, rock walls and even an alpine house full of rare and unusual alpine plants. Learn about the construction of these rock gardens and the plants that grow in this 4.5-acre public botanic garden through stunning pictures and in depth stories.
A passion for skiing and mountains brought Nick Courtens to Vail, Colorado in the spring of 2010 after completing the Professional Horticulture program at Longwood Gardens in Pennsylvania. Alpine plants and rock gardening quickly became Nick’s new passion after a summer internship at Betty Ford Alpine Gardens. Since then, Nick has become the Curator of Plant Collections at Betty Ford where he oversees the maintenance, design, propagation and curation of the living collections. In recent years, Nick has been responsible for building several new rock gardens, perennial gardens and an alpine house while also participating in seed collecting in the rocky mountains and travelling abroad to learn about alpine environments and gardens.

Thurs March 9, 2023 7:00pm: Adam Yakabuskie, For the Love of Peonies
This Zoom hybrid meeting will feature Adam Yakabuskie speaking on the types and cultivation of peonies in our area. Adam is the owner of Parkland Peonies. Adam says, “I grew up on a small farm in Ontario and for

Peony nursery, Alberta
us kids working on the land was more of a chore than a pleasure. However, that experience made me receptive and appreciative of the beauty of living plants. So when I moved to Calgary in my 30’s, the desire to grow flowers came naturally to me. Together with my first wife we turned bare land of our yard into a beautiful flower garden. In 2008, our passion for horticulture got us featured in Vol. 22 “Gardens West” magazine as the winners of the monthly garden competition!
At that time, I also started growing and breeding Asiatic, Oriental and Martagon Lilies on a little piece of land that I was renting from a local farmer. I had much delight in seeing these beauties grow and bloom for me every year: the only thing that set me back was the constant fight with the lily beetle that seemed to be liking my lilies way too much.
However, my dream to live on the land and develop gorgeous gardens and flower fields for people to visit and enjoy became even bigger. It was around that time in 2016 that I was offered to purchase a peony business from Bob Yaremko, who had a collection of 450 peony varieties – Bob was the owner of Parkland Perennials which had a rich history of delivering customers with beautiful peonies for almost 40 years. Once introduced to the beauty, hardiness and magnificence of the peony plant I decided to continue Bob’s legacy”.
This meeting, held in-person at Lakeview Community Hall, will be live-streamed via Zoom for those members at home. CRAGS members who wish to participate via Zoom do not have to register. Non-members who wish to participate in the Zoom talk may register via Eventbrite.

Ian Young in his garden
Ian Young, a distinguished gardener and author from Aberdeen, Scotland, will speak to CRAGS about plants in the Ericaceae family, which includes heathers, rhododendrons and many others.
Ian Young has had a lifelong interest in plants and along with his wife Margaret has developed a well-stocked garden in Aberdeen. Over more than forty years the trees and shrubs have matured and Ian has developed a rich under planting of bulbs and woodland plants which provides a progression of seasonal colour, texture and form. Most of the plants, including bulbs, trees and shrubs, have been raised from seed.
Ian is also experienced in alpines and rock gardens having developed various innovative ways of making troughs including the method of turning polystyrene (Styrofoam) fish boxes into troughs that mimic the appearance of real stone. At the Scottish Rock Garden Club he has won many Gold Medals and Best in Show Awards at National Shows using these troughs and this method has been taken up widely, with demonstrations of the technique being given across the UK, in New Zealand, Canada and America by all sorts of different alpine groups.
For twenty years Ian has written a weekly online diary, the Bulb Log, where he shares his enthusiasm for plants and their garden. In 2015 he also started a YouTube channel where there are over 180 videos from the garden.
He has published an electronic book ‘Erythroniums in Cultivation’ which is available for free download at SRGC.net
Ian has lectured widely in the UK, Europe, Scandinavia, New Zealand, USA and Canada including at many prestigious international conferences. For over 15 years he was a regular broadcaster on BBC Radio Scotland.
Ian is also an artist and photographer and uses both these skills in the garden and his presentations.
In 2007 he and Margaret were honoured to be (jointly) awarded the Queen Elizabeth, the Queen Mother Medal by the Royal Caledonian Horticultural Society for outstanding service to Scottish horticulture. In 2008 Ian was awarded the SRGC Golden Jubilee Salver for outstanding service to the SRGC. In 2020 Ian was awarded the Veitch Memorial Medal by the Royal Horticultural Society for ‘exceptional involvement in the advancement of the science art and practice of horticulture’.

Thursday Nov 10, 2022: AGM and Ken Wright
This will be a combined in-person and Zoom meeting, starting at 7 pm. Members will receive a reminder email with the Zoom links.
First, CRAGS’ Annual General Meeting for fiscal year 2021-2022 will take about 30 minutes, followed by our speaker.
Our speaker, Ken Wright, will discuss growing native plants and will be at Lakeview Hall to include a demo of cleaning seeds, stratifying and planting methods.
Ken Wright is the founder of Bow Point Nursery, and he presently owns Wright Nursery, a wholesale nursery started in 2015 as a supplier of native seed sourced plugs and seedlings.

Ken Wright
In 1988 Ken and his wife Pam started Bow Point Nursery with the objective to supply native, indigenous woody plants for urban and rural landscapes. Initially Ken was growing and starting the nursery, Pam was landscaping and using the plants they grew in her landscapes. As time passed and the nursery got busier, Pam shut down landscapes and they started working together at Bow Point Nursery. Ken says, “We learned as we grew – when to pick seed (right before the birds take it) , propagation methods and the marketing of native woody plants. And of course, travelling the back roads of Southern Alberta looking for the native plants growing there. We always were looking for the trees and shrubs that were growing in the most rigorous sites – those open, full sun, windy and generally harsh conditions – of which Southern Alberta has many. That became our full time focus – selecting plants and seed sources, picking seed, cleaning and storing seed, germinating/propagating and growing those plants into landscape sized trees and shrubs.
In 2015 we sold Bow Point Nursery – our goal was to move to a new site 2 hours north by Caroline, Alberta. We did start a new nursery -with a different goal – to focus on selecting plants, collecting seed and propagating our native trees and shrubs. The main difference this time around – no retail and no employees. It has been a great adventure which continues”.
Thursday Oct 13, 2022: Gary Stedman on Adding Roses to your Garden

Gary Stedman
This will be a combined in-person and Zoom meeting.starting at 7pm.
Gary Stedman is a former board member of the Calgary Rose Society. His interest in gardening started at a young age working with his grandfather in his vegetable garden in Southern Ontario. After retiring, he and his wife have been successively rehabilitating their various flower and vegetable beds and introducing roses into the mix. At the Ann and Sandy Cross Conservation Area, he is leading a special project to re-introduce native grasses and plants and remediate a natural growth area. Over the past couple of years, he has taken advantage of the emerging virtual training options, completing a number of courses in insect identification and management, zone 3 vegetable gardening, and, most recently, gaining his Master Gardener of Alberta Certification.
Thursday Sept 8: Plant Sale and talk by Janet Melrose on Rewilding the Urban Garden
Check out CRAGS’ annual “Last Chance Plant Sale” on Thursday Sept 8 from 6pm to 7pm, outdoors at Lakeview Community Hall, 6110 – 34th Street SW, Calgary. Member growers will offer a variety of alpine and other plants and now that the heat wave has passed, we should be able to get them in the ground!
Then at 7:30pm, we are delighted to welcome Calgary speaker Janet Melrose, who will talk about Rewilding the Urban Garden.
This will be a combined in-person and Zoom meeting, to be held at Lakeview Community Hall. Members will receive an emailed reminder with the Zoom links. Non-members who wish to view the Zoom talk may register at Eventbrite for $8.
Wilding or perhaps more appropriately “rewilding” the garden looks gardens in a different way than the usual tamed spaces that have dominated gardening for the past few decades. Instead of attempting to control nature the goal is to invite nature back to our gardens.
In our current environment where climate change, loss of habitat and unceasing human incursions into wild areas is putting all species at risk, letting go of old values and ways of gardening and embracing the wild side is an important way for gardeners to contribute to creating healthy ecosystems, with habitat for wildlife, and even cumulatively modify our climate.
This talk will look at the down to earth design and cultural practices that we can use to make our gardens refugia for pollinators, other beneficial insects, birds and other life.
Janet Melrose is ‘Calgary’s Cottage Gardener’- Garden consultant, coach, educator and Horticultural Therapist. Her motto is ‘Grow, Nurture, and Bloom’.
She shares her passion for gardening and knowledge through workshops and writing for ‘The Gardener for Cold Climates’ and ‘Calgary Gardening’ magazines, and now co-author with Sheryl Normandeau for the Guides for Prairie Gardeners series of books.
