Mary Ann Van Berlo - Pushing the Zone Limit
**ZOOM ONLY ** Zoom Link

​Discover plants that will grow in our area despite being ‘not hardy’ according to their label.  Mary Ann will share information on some of the unusual plants that she’s successfully grown in both her former rural Ottawa garden and in her current Maitland garden.  She will provide some cultivation tips that she’s learned from trial and error over the years. 

Mary Ann Van Berlo is an avid gardener who enjoys everything horticulture.  She collects plants and her 2.4-acre garden on the St. Lawrence River has many uncommon varieties.  Mary Ann is not afraid to push the zone limit, and grows a number of plants that shouldn’t really be hardy in this area.   In June 2017, Mary Ann’s garden was featured in Ontario Gardener Magazine.

As another gardening season approaches, it’s a good time to think about how we garden in relation to the urgent environmental issues facing us. Our aim is always for beautiful garden spaces, of course, and rock gardens can be a part of this. But can we really do anything substantive to help preserve and create biodiverse, wildlife-friendly landscapes, and deal with climate change? (Yes!) Josie will talk about the best practices for encouraging a healthy ecological system within your own lovely garden and beyond.

Josie has been active in the Ottawa area gardening community since the late 1990’s, working as a volunteer with the Master Gardeners, the Ottawa Horticultural Society, Canadensis, and the Ottawa Valley Rock Gardening and Horticultural Society. She studied horticulture at Algonquin College, and continues to learn with Master Gardeners and to take advantage of all the opportunities available to us. Josie has had a small personal business consulting and coaching, helping people design their gardens and solve garden problems. She makes sure to emphasize the importance of following best practices to support biodiversity and our native ecology. But rocky landscapes, alpines and other small plants are the ones that really excite her imagination. She finds growing them from seed can be fascinating, even when some don’t germinate as we wish!

Ken Allison - Exciting Plants in the Alvar

 

Full description to follow

An alvar is a unique type of grassland or open woodland found on shallow, nutrient-poor soils over bedrock, often with a flat, rocky surface. These ecosystems are characterized by sparse vegetation and high biodiversity.

These plants are well-adapted to the harsh, dry conditions of alvars.
