Bumble bees feed on nectar from flowering plants and are a beneficial insect because they pollinate crops and other plants. hey will sometimes build their nests in soffits of attics or other sites around houses or buildings. A disturbed bumble bee will buzz loudly.
You can make wine from the petals. You can use it as a diuretic for medicinal purposes. You can use the leaves from a young plant for part of a salad (not if it has been sprayed with toxic chemicals!). This plant is beneficial in MANY ways!
