  Mua, Muah, Muas, Muak all are the equivalent of 'Mwah'. Onomatopeiac word for a kiss, ie on the end of a text message or email.
Bees see the world much differently than people do. A small cluster of tomato blossoms won't catch their attention, but a lawn peppered with clover and dandelions sends then into a pollinating frenzy. If you're serious about attracting bees to your vegetable garden, plant flowers.
If you are looking to attract hummingbirds and butterflies to plants around your home, keep in mind that they feed on nectar-producing plants such as butterfly bushes, sedum, honeysuckle bushes, verbena, and bee balm. Hummingbirds especially like bright-colored plants.
