Be careful what you buy - many of the wildflower packs are garbage and quite a few have flower types whose seeds require fire to germinate. Read the packs before you buy.

Many of these are great for beginners.

Sage and Thyme are super easy to grow-you can get a variety of thyme options from your nursery. Grow from plants rather than seeds to have them succeed earlier. I've never seen bees on my varieties though.

Lavender is a pain to germinate-I'd buy plants rather than seeds.

Find a wildflower mix native to your area! has bulk seeds on the, well, cheap. As others have said, make sure they're beneficial and not invasive.

Black eyed Susans and anything in the mint family (including bee balm) will spread quickly.

I planted just regular spearmint and the bees go absolutely crazy for it.

One thing to look for would be plant descriptions like "self sows regularly" "spreads aggressively" "not recommended for small gardens" etc. as you'll get more bang for your buck. Honeybees definitely LOVE basil, which blooms all summer long. If you pluck the buds, the plants get bushier and grow more outward. If you don't pluck, they get taller. Either way you'll have more basil leaves than you know what to do with.

The flowers are actually quite pretty in my opinion. I grow some specifically to attract bees and plant them near my vegetables to encourage pollination of them. Not sure if it works, but I like the look of the basil flowers and I like providing the bees some pollen.

Zinnias are some of the easiest flowers to grow. Just get some seed packets, rough up the soil, and scatter the seeds in a sunny location after the last frost. Water from time to time, but they are pretty tough plants.

Borage grows like a weed in well-draining soil when planted from seed. Do not start indoors. It has a long long tap root and does better directly sown.

This is the biggest draw of bees to my garden. Bees love, borage.
