The flower fragrance seems week bergamot-like with a peppery twist.

„It is commonly used in gardens for its attractiveness to bees, ability to improve poor sandy soils with their nitrogen fixing ability and flowers; numerous cultivars have been selected… Low alkaloidal or sweet cultivars of this lupine suitable for fodder crops have been bred.“

The flower volatiles are dominated by trans-β-ocimene and trans-β-farnesene, which together comprise over 50% of the fragrance. Minor constituents are sabinene, myrcene, limonene, linalool, α-copaene, β-cubebene and trans-α-bergamotene.
