The flowers are mostly visited by [[bumblebee]]s.<ref>{{Cite journal | doi = 10.1111/plb.12328| title = Competition for pollinators and intra-communal spectral dissimilarity of flowers| journal = Plant Biology| pages = 56–62| year = 2015| last1 = Van Der Kooi | first1 = C.

The majority of lupines do not thrive in rich heavy soils, and often only live for a matter of years if grown in such places, because crown contact with manure or rich organic matter encourages rotting.
