| Any time you have flowers, you may get all sorts of insects and sometimes bees and wasps. There are usually certain types of flowers that bees prefer but it often depends on your specific location and what all is located in the area around you. Ie., if there is a great source of material for bees in someone's yard, then they may mostly gravitate there and a few solitary bees might visit you. This may be more or less depending on how close you are to the ground and near areas where bees/wasps may build their hives. In my case, I grow blueberries on my balcony and those are bee-pollinated, so every year, I do pray for mild enough temps for the bees to be active enough to come up here and pollinate my blueberry flowers. In most cases, I get carpenter bees doing that as I rarely see bumble bees up here - at least when the blueberry is blooming. 
Last year was my first full year with a beautyberry and when it started blooming, I did get a whole pile of what I think were bumble bees that were all over it! Of course that helped because that's how I got a nice crop of berries! I have the beautyberry situated in the far western corner of my balcony away from where I frequent so I don't run into them that much and they're too busy getting that nectar. 
The only time I tend to have issues is late summer when paper wasps are out in force and they end up hanging out on my hummingbird feeder. In the past, I've also seen them on my moonflower vine, but that seemed to be an odd year where they may have also been attracted to the over-active nectaries (which produce big drops of nectar at the base of a leaf) on that particular vine. The hummers tend to steer clear of the wasps but will still come back to feed: 
But hummers will definitely chase away (or be chased by) a carpenter bee. The carpenter bees don't care about the feeder but they are territorial like the hummer and I've seen many a chase between the two! LOL |
