Lecture - Gardenlust – A Botanical Tour of the World's Best New Gardens

 

For three years, Chris Woods traveled the world seeking out contemporary gardens and found 50 of the best. With wit and humor, he describes the most arresting features in public parks in exotic locations like New Delhi and Dubai, mission-redefining botanic gardens in Chile and Australia, and the most enviable details of lavish private estates and gemlike city yards. Throughout, he reveals the fascinating people, plants and stories that make these gardens so lust-worthy.

Chris Woods was born in London, England but has lived in the United States since 1981. He has worked in the garden world as gardener, director and designer for 45 years. He is best-known for his work at Chanticleer, a “pleasure garden” in Wayne, PA, where he worked for 20 years.

After Chanticleer, he became vice president for horticulture at the Santa Barbara Botanical Garden. He was director of the VanDusen Botanical Garden in Vancouver, Canada, and executive director of the Mendocino Coast Botanical Garden. In 2012, he was lured back east by The Pennsylvania Horticultural Society and appointed director of its private estate and garden, Meadowbrook Farm. He has been a consultant for Botanic Gardens Conservation International, the Garden Conservancy, and the Chicago Parks Department. He has served on a number of boards, notably the American Public Gardens Association and the Fairmount Park Conservancy. Being somewhat restless and increasingly unemployable, he decided to stop managing gardens and decided to travel the world looking at both constructed and wild landscapes.

He currently lives in California and one or two other places.

Sustainable Greenhouse Design

Rocky Mountain Gardening Elective

Have you ever wondered if a greenhouse that needs NO supplemental heating or cooling could be made? The answer is yes!

No more over-heating and freezing in all-glazed greenhouses. The sustainable design balances the use of thermal mass, glazing, insulation and sun angles to achieve the stabilization needed in our extreme climate without the use of fossil fuels. Learn how to design a sustainable greenhouse from the ground up, using salvaged or new materials to achieve the look and performance you want. You can also use these techniques to improve an existing greenhouse.

This class is a comprehensive look at how passive solar greenhouses work and covers topics such as how to orient the building, basic principles of passive solar design including the use of stored water as thermal mass, simple math formulas to help guide your design, a materials list and drawings and calculations for a 13’ x 15’ greenhouse.

In 2000, the Parmenters built their first greenhouse out of 90% recycled materials on top of an 8,120 ft. elevation decomposed granite mountain. Since then, they have designed and built many more and are ready to share what they have learned about state-of-the-art materials and cost-saving strategies. Lose yourself in a year round garden sanctuary.

On the third Wednesday of every month (April – October) wander with one of these authors through our acres of naturalistic gardens to see which wildflowers are at their peak. Since many bloom at Denver’s elevation before they bloom in the mountains, seeing them here first can help you learn what to look for, where and when.

What Made My Good Plant Go Bad?

Rocky Mountain Gardening Elective

Did the glorious beauty promised by the garden catalog, nursery salesperson or garden designer fall flat? You may be surprised that insects and diseases are NOT the main cause of problems in the garden. Gardeners have more control than they may think over many plant problems. As much as we do not like to think it, humans cause most of the issues in the garden; many of which result in an insect or disease problem as a secondary issue   NOT the first.  This provides an overview of the most common plant challenges and what you can do to prevent their annual recurrence. The course focuses on the root causes that eventually attracts pests and disease to your garden and what to do about it.

 

Price: $44, $39 members

Instructor: Patti O'Neal

 

Special Instructions: This class is a lecture and hands on lab. You may bring a sample of a plant or turf you want diagnosed to class. Registration confirmation includes info on how to collect a good sample.
