This Mountain Cornflower (Centaurea Triumfettii) is a Bumble Bee approved blossom known for abundant nectar produced which naturally attracts many insect pollinators such as bees.
Centaurea Triumfettii is a plant belonging to genus Centaurea herbaceous species of thistle-like flowering plants from the Asteraceae family of knapweeds that are very robust and tend to dominate adjoining areas of landscapes where they grow, I know this from personal experience in our backyard flower garden.
When these are in blossom in May I’ve noticed a lot of insects like bees including the Bumble Bee regularly visiting and extracting the high nectar content meanwhile, picking up pollen however, another insect I don’t like or want also visits in abundance, ants including the black carpenter ants.
Squarrose Knapweed is another name used to describe this herbaceous perennial plant growing 30–60 centimetres (12–24 in) high and its flowers normally last until August.
As my picture shows, its inner flowers are bright purple while the outer ones azure blue or deep mauve, a very attractive combination then again, many very common invasive weeds also have similar attributes going for them as experience has shown.
