Lysimachia species often have yellow flowers, and grow vigorously. They tend to grow in damp conditions. Several species within Lysimachia are commonly called loosestrife, although this name is also used for plants within the genus Lythrum. The genus is named in honor of Lysimachus, a king of ancient Sicily, who is said to have calmed a mad ox by feeding it a member of the genus.[5]
Bees of the genus Macropis are specialized to pollinate oil-producing Lysimachia plants. These bees use exclusively Lysimachia floral oils for building their nests and provisioning cells. Lysimachia floral-specific chemicals are strong attractors for Macropis nuda and Macropis fulvipes bees that are seldom found in other plant genera.[6]
