I live in Baltimore City. In the summer of 2017 a lovely vine began growing on my pea arbor. I let it grow as the leaves were interesting and no one I knew could name the plant. Low and behold, the most exotic flower I had ever seen was formed. I knew I had a passion flower vine, Passiflora incarnata to be exact. That summer I also planted catnip and the mint grew and bloomed well. And then to my great surprise, by the end of summer, I was favored by the presence of three humming birds and they were enjoying the tiny white catnip flowers! While I understand hummingbirds may also enjoy the passion flowers, I expect that the carpenter bees that live in my wooden fence and may be the plant's primary pollinators. That year I decided to purchase a feeder for the birds and set it out with sugar water. The following year, in the late summer, the humming birds returned, and so did the passiflora incarnata, but with a vengeance. The flower vines (that produced much fruit) tried to take over my vegetable garden and almost succeeded in strangling the tomato plants. My questions are as follows. I want to hummingbirds to come back and feel welcome. I have planted a trumpet vine in a barrel with hopes that the red flowers will be beneficial for the little birds. I get the idea that a natural food source would be better for them than the sugar water, but that might not be true. The catnip is still in place and I will put the sugar water feeder out once more. However, the passion flowers need to be kept in check, so they don't take over. I need some suggestions on how to deal with the plants so I can keep my vegetable garden productive, and keep the humming birds happy as well. I want them to return.
