its a myth that bats polonate flowers they might be around flower to eat the bugs that polanate them. And there a critter that looks like a humming brid but its a moth with a long snout. But they come out at night.

For native plants try some datura they grow all over Canada.

Just a quick note. I looked into it and found that there are no plants that are pollinated by bats in Canada, however many are pollinated by bats elsewhere. It is not a myth at all. Secondly, all Daturas found in Canada are introduced. Some are listed as noxious weeds in the States.

I agree. The Datura are truly a tropical annual. They do however drop seed ( the white one ), and SOMETIMES come back from seed, if the site is a protected one.

The moths are luna moths. Huge is the word....about the size of a hummingbird. They love the Brugmansia that I grow, but I have not seen them on my Datura. The first time I saw them I almost freaked out wondering what the @#$% was attacking my Brugs. No worry though.
