Busy Bee on Velvet Queen Sunflower In My Garden

We have been trying to plant flowers to attract pollinators because there just doesn't seem to be that many around. I was just telling my husband that I was thinking of bringing in some solitary bees from somewhere. That's something I'd need to do more research on but perhaps it's better to be patient and wait for them to come. I will definitely be planting more, lots more, sunflowers!
