Our winter visit to the Montreal Botanical Garden

Traveling always presents challenges…What to do when you have a 22-hour layover in Montreal? Book a hotel, get up early and take an Uber to the Montreal Botanical Garden, otherwise known as Le Jardin Botanique de Montréal…after all it is in the French-speaking province of Quebec. Yes, there was an icy layer of snow outdoors, but inside the 10 greenhouse complex, there was flora to excite even the most jaded botanist. Check out this sensational planted wall with Begonia, Pothos, Tillandsia, Prayer Plants and more.The orchid house was full of treasures. Epiphytic plants cascaded from the rafters.

Each greenhouse focuses on a specific plant group, with specimens arranged in an aesthetically pleasing manner.  Here is the view from the catwalk in the Aroid,  Cycad and Palm House.The Succulent Greenhouse … with Mexican themed architecturecloseup of the hanging Rhipsalis floccosa

More temperate plantings were found in the cooler Asian themed greenhouse.An  exquisite 45 year old Penjing specimen of Pyrancantha crenulataSweetly fragrant Wintersweet, Chimonanthus praecox, which wouldn’t be hardy outdoors in Montreal or most of Massachusetts for that matter, was in full bloom indoors in January.There are many educational exhibits that are artfully conceived. Here cut stems of Red Twig Dogwood are inserted in a wooden platform, echoing the stems outdoors in the distance. Floating from the rafters above is a montage of recycled trash…yes…what we fill our landfills with.Another view of the recycled assemblage.Chris and I didn’t have time to walk the grounds, even though the winter landscape beckoned. The staff we spoke with were extremely knowledgable and quite proud of their garden, as well they should be.  If you are looking for a flora filled winter escape, the greenhouses here are exceptional. We definitely want to return this summer or fall. 

…wish you had a Winter Greenhouse?

The Aloes begin to bloom in January

Maybe it’s a luxury, or maybe not…

One of the perks of running a nursery is that on any winter morning I can walk out to the heated 100′ greenhouse and smell the promise of spring. We can’t afford to have the heat cranked up….the thermostat is set at 55F in the warmer half, just enough heat to keep our Begonia collection from pouting . The rear 50′ section drops to 45F at night, and this is where we store our Salvia, Phormium, tender succulents, and plants for forcing.  As the daylight hours gradually increase, early blooming plants set buds and begin to unfurl.

Today’s arrangement of cut and forced material, including Daphne, Hellebores, Echeveria, Aeonium , Begonia and Ivy

Up until a half  century ago, it was not uncommon for gardeners to have some form of greenhouse structure to protect tender plants, force bulbs and other flowers for arranging, grow herbs and to get a start on seed sowing. For the most part these were not formal glass houses, but homemade lean to’s and pit frames built into a south facing slope or dug into the earth to take advantage of geothermal warming. These “pits” were excavated to a depth of 4′ or more, with hay bales tucked along the perimeter for insulation. Recycled window sashes were used to allow light into the frames, as these were the days before plastic and polyethylene.

A dear gardening friend, Elinor Malcom, who was one of our nursery’s first customers, loved her “pit” in Carlisle MA. where she wintered over many treasures including a collection of Camellias that belonged to her mother. Ellie’s mom had been an accomplished gardener and was good friends with Kathryn Taylor, who co-authored with Edith Gregg, the book Winter Flowers in Greenhouse and Sun-heated Pit, first published in 1941, now out of print.  My husband Chris was lucky to find a copy in a local used book store sometime ago. (PS…your library may have a copy!)

This practical book does go into the how-to’s of small greenhouse growing, but I think the authors hit a happy nerve with their enthusiasm for solar pit houses. Ms. Taylor and Ms. Gregg showed how, with a little Yankee ingenuity and thriftiness, the average home gardener could have the luxury of blossoms and greenery during the winter months without electricity or heating units. The prose is entertaining and easy to understand and there are a number of good technical illustrations as well as charming B & W photographs.The women shared not only their successes but some of the pitfalls they encountered (no pun intended). The last chapters focus on recommended plants for winter forcing. I was greatly impressed with their expertise and ability to use materials  that were easy to be had without great expense, and I loved the simple but direct dedication at the book’s beginning: To the husbands who dug the holes”.

An online search indicated Winter Flowers in Greenhouse and Sunheated Pit is available as a used book on Amazon, but I would also recommend checking out second hand book shops.  For those who are interested in learning more about constructing a pit greenhouse, check out these links: Mother Earth News,  Inspiration  Green, and Solar Innovations. There are now many publications on the subject, some more suited to commercial growing.

Wouldn’t it help you to get through the winter if you could walk out your door after a snowstorm and bring in a gathering of fresh flowers and greenery?
