  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.
The bees certainly do. Clover honey is one of the most common types of honey available, and bees visit red clover throughout the summer and fall. The edible flowers are slightly sweet. You can pull the petals from the flower head and add them to salads throughout the summer.
