I've heard that bees like blue flowers, so things like borage and buddleias
are good, along with rosemary and lavenders of course.

Buddleias?? Are you serious? I can't say I've ever seen a bee on a
buddleia. Only butterflies. Possibly the flowers are too deep for the
bee to dip its tongue in? I shall investigate more closely!

But the most bees I've
seen per square cm were on some thyme flowers at Mount Tomah Botanical Gardens
-- you couldn't actually see the thyme!

That would make an interesting-tasting honey.

My award for "best bee attractant" would go to a plant that combines
a long flowering period (up to 6 months with the lavender I mentioned,
I would estimate), with a large number of flowers per sq metre of
garden bed.
