Attracting bees and butterflies

I was reading about flower and plant selection for the yard. I don't usually spend much time on non food-producing plants, mainly due to lack of funds.
But this year, I am going to try to work around that.
The fact that there is a world-wide shortage of pollinators makes it a good idea to consider plants that attract bees and butterflies according to ReneesGarden.com.
Common flowers that do a great job are poppy, lupine, viola, wallflower, black-eyed Susan, Butterfly flower, Calendula, Dahlia, Amaranth, Marigold, Salvia, Sunflower, Zinnia, Portulaca, Lavender, Foxglove, Cosmos, Coneflower and Echinacea,
Anybody who has run barefoot in a yard knows that clover attracts bees. It is a great ground cover plant too.
Garden plants that are highly attractive to bees and butterflies include parsley, cilantro, thyme, dill, basil, chives, peas, squash and pumpkin. So I will plant as much of these as I can.
