The best way is to see what is being sold at your local nursery/plant shop since they only stock plants that will thrive in your area. Make sure to read the plant information stick or ask the sales help if the plant will attract bees or other insects. You also want plants that require little care/watering.

Just about any flower that comes from bulbs/corms (tulip, daffodil, hyacinth, snow drops, crocus, freesia, gladiolas, etc.) or rhizomes (iris, calla lilly, canna) are pretty much bee-free since they don't require cross pollination to bloom. Some of these should be planted in the fall for spring bloom time and others can be planted in the spring for summer blooms. Check with your local nursery or home improvement store - even the garden shop at Walmart for what is available to plant now in your area.

You could try colored-leaf plants like coleus (they eventually get a small flower directly on top, which you can pinch off), caladium, small hosta (there are some beautiful color variegations, they get only one flower stalk bloom, but many people pinch them off with no harm to the plant), succulents like hens & chicks, etc.
