Saving Glass Gardens: the Parkwood NHS Greenhouses

 

Saving Glass Gardens

The greenhouses of Parkwood National Historic Site

 

Pre Conservation work

 

Glass Garden was a common terms for early 20th century greenhouse. For Canadian auto-baron Sam McLaughlin and his wife Adelaide, their glass gardens were enormously practical and highly decorative, providing plants for year round display as well as for the elaborate gardens. 

The Parkwood greenhouses also supported the
family's social pursuits, providing horticultural novelty & entertainment for guests, and the ability to compete and flower shows against others of green thumb and deep pockets.

Garden clubs and societies, from across Ontario and beyond, were frequently
entertained at Parkwood. Invitations to the McLaughlin’s annual Chrysanthemum Tea were coveted for over five decades, when guests came to wander the greenhouses and marvel at the 250 unusual varieties displayed, especially the large single- stemmed plants trained to have just one spectacular bloom.

Today, an engraved invitation is no longer required. Parkwood’s greenhouses are open to the public all year, for education& enjoyment. Now approaching 100 years of age, they still perform many of their historic functions for display and plant production for the gardens.


In  2012 Parkwood began a partnership with Durham College  in  a  Horticulture Technician Program that uses the historic gardens and greenhouses for teaching and lab purposes – extending their education value even further.

 

Why Save?

Parkwood's glass gardens speak to the vanished lifestyle of the early 20th century. They illustrate construction techniques and greenhouse operations of the era, and help visitors imagine the lavish lifestyle of the McLaughlins, and the roles played by their large garden staff (24+) in keeping up appearances. 

 

Why Now?

The greenhouse complex is at serious risk of loss to

the historic building fabric, and of public access and student use due to deteriorated unsafe conditions.

 

Who will benefit?

The greenhouses or glass gardens provide opportunities for education and enjoyment to area residents and visitors from across Canada and around the world, and even more specialised opportunities for horticultural enthusiasts and students.Many volunteers take part in both plant production  and  display  activities  including seniors and apartment dwellers without gardens of  their  own.   

Parkwood’s greenhouses offer  a chance to socialize and keep limbs and green thumbs active.

 

What’s Involved?

Each greenhouse or glass garden has different

requirements, due to its evolution and current condition.

Parkwood has engaged top heritage specialists in historic assessment and future planning.

Together we have determined a course of repair which respects historic values and ensures that each greenhouse can be sustained for 100 years more.

 

Work in progress

Conservation Completed

A pilot project was begun in late 2013, to test the “prescription” and launch a repair sequence for the remaining 5 greenhouses.   The pilot project involved  a  restoration  of  the  c.  1917  Vinery, which still houses one historic grapevine.   The project is complete and the results are stunning, encouraging the public to picture the other glass gardens fully conserved/restored. Community partners rallied to raise $ 200,000 to do this pilot work, but more dollars are urgently required.

One highly visual element of the complete project will be replacement of the decades-old plastic panels now yellowed and opaque, and a return to clear glass .
 

The next glass garden to undertake is the large and wonderful Palm House, home to many tropical plants including a large rubber tree planted by McLaughlin and his Head Gardener, and where Flora a marble sculpture of a woman takes centre stage.

 

The Palm House connects directly with the recreation  wing  of  the  mansion for seamless public access year-round. Its restoration program is pegged at just over $ 400,000.
