I have seen quite a few huming birds in the past usually in July but I was out in Barhead at a friends acerage and she had some already and she had a feeder by her lilace tree. I usually plant a scralette runner ak bean plant and I buy a bright fushia for under the kitchen window and a red and pink petunias in a hanging basket with my feeder under the kitchen window, hope this helps other people who are trying to attract hummers in mid northern Alberta.
