The first Saturday in September is National Hummingbird Day, though which nation it is celebrating it, the calendars I have found refuse to say. They’re a charismatic creature and it’s no surprise people like to look out for them. What did surprise me is how far north they’re recorded. Hummingbirds Canada includes observations in the Northwest Territories and Nunavut. If you want to attract hummingbirds to your garden then the right plants can help. Hummingbirds Canada recommends a lot of plants, but you’ll find a lot share a similar feature. They tend to be red flowers, with tubes but, as Chicago Botanic Garden points out, they’re capable of feeding across a wider range of flowers than that. It is possible that this flexibility in hummingbirds has meant they haven’t influenced plant evolution as strongly as insect pollinators have. A recent study found that while some plant lineages diversified after adapting to hummingbird pollination, some did not and in some diversity even reduced, which seems odd. One possible explanation is that hummingbirds with their longer range than insects have helped genes flow over greater areas, reducing speciation. With some species travelling up to a thousand miles as they migrate, they can cover a lot of distance. How to Play Six plants fill each row each column, each box of six no bloom may repeat Tap an empty cell then choose your plant from below watch the garden grow Or pick a plant first then tap the cells where it goes faster hands plant more Red borders will warn when two alike share a line rethink and replant Ticked plants rest complete all six placed in rightful soil fewer choices left The clock starts to run the moment your first plant falls how swift is your hand? Select a plant, then tap cells Two ways to play: Tap an empty cell then pick a plant, or select a plant below then tap cells to place it.
