Some gardeners may be able to grow palms and even cold-hardy citrus in parts of Canada, according to the federal government's latest Plant Hardiness Zones map, the first update since 2014. The map, first developed in the 1960s and updated every 10 years in the last few decades, looks at what can grow across the country, based on temperature, precipitation and other weather patterns. It found that some plants can now grow in regions they couldn't have previously, while other areas can host new plants entirely. Much of that is due to the steady march of climate change. In this way, each map update has marked an increasingly warm Canada.
