Pretty much anything in bloom but they do like small tubular flowers
Basil, alyssum, avocado, citrus trees, sage, sunflowers, clover, lavender, verbena, hyssop.
Honey will taste different depending on what nectar and pollen the bees are feeding on and the color will also change.
Most of the foraging bees are not aggressive especially if they are not Africanized. I have bees that visit my alyssum, cuphea, sage, lavender, verbena, basil, and sunflowers when they are in bloom. The will come mainly in the mornings after the sun has warmed up and again in the afternoons. I don't usually see the bees in the cold part of the morning or at middday (except a few strays when there aren't many flowers around). They get used to you being around but you do need to be careful what you touch. I was weeding my ground cover once and did not realize a bee was on my pick and I got stung. Usually, I can stand less than a foot from foraging bees and they usually give a warning buzz to back off when I get too close. If I need to work somewhere they are foraging. I gently push them with a shower from the garden hose just in the section I need to work. They usually get the message and move to another part.
Happy gardening in Hawaii. Gardens are where people grow.
