Atlantic Canada鈥檚 largest city has a new, and highly unlikely, tropical flavour.

Nine palm trees have been planted in four Halifax parks, although the jury is out on whether they can survive winter in a North Atlantic city known as the Warden of the North.

The parks, all on the Dartmouth side of Halifax Harbour, now feature cold-hardy palm varieties that can grow in more northerly climates of Asia like China and Japan, or from areas of the continent with high altitudes such as northern India.

The varieties include windmill and miniature Chusan palm, which are native to parts of Asia; needle palm, which is found in the southern U.S. states like Florida; and pindo palm, native to South America.

Municipal horticulturalist Chris Poole said aside from wanting to see if the palms can survive, it鈥檚 also part of his job to create public interest and to encourage people to enjoy the city鈥檚 public spaces.

鈥淚 think by planting these palms around we鈥檝e certainly achieved that and more,鈥� said Poole, who noted windmill palms as a tall variety that look like a typical palm tree.

鈥淭hey are certainly the ones that are creating the most buzz because when you take one look at them it just looks as if you are in a different part of the world,鈥� he said.

Palms are grown elsewhere in certain parts of Canada, most successfully in Vancouver 鈥� one of the warmest of the country鈥檚 big cities during winter.

By contrast, the minimum daily temperature in Dartmouth averages minus 8 degrees Celsius in January and February, according to data from Environment Canada. And temperatures can dip well below that during typical cold snaps.

Ben Freeman, a post-doctoral researcher at the University of British Columbia鈥檚 Biodiversity Research Centre, is skeptical of Halifax鈥檚 palm plan although he 鈥渁pplauds the ambition.鈥�

He said the trees鈥� keys to survival in more northerly climates are cold and frost tolerance.

鈥淯nless you actually go and try you don鈥檛 know whether they will survive, but I鈥檓 guessing that Halifax is too big a jump right now with current climates for palms,鈥� Freeman said.

Still, Freeman thinks Halifax鈥檚 experiment is 鈥減retty interesting,鈥� because climate change has made colder places a little bit warmer.

鈥淚t really is true that you can plant palm trees a little bit further north than you used to be able to 50 years ago,鈥� he said. 鈥淏ut I don鈥檛 have high hopes for the long-term survival of palm trees in Halifax.鈥�

Egan Davis, lead instructor of horticulture training at UBC Botanical Garden in Vancouver, said he sees the windmill palm as the only species with a chance of surviving a winter climate like Halifax.

Halifax has planted exotic species with various degrees of success in the past, including coffee and pineapple.

Most recently, an agave bloomed last month in the city鈥檚 renowned Public Gardens. The plant had spent most of its life in the city greenhouse before being transplanted outside this spring, drawing curious crowds.
