Lysimachia
''Lysimachia'' ( ) is a genus consisting of 182 accepted species of flowering plants traditionally classified in the family Primulaceae. Based on a molecular phylogenetic study it was transferred to the family Myrsinaceae, before this family was later merged into the Primulaceae. Characteristics ''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. ''Lysimachia'' species are used as food plants by the larvae of some butterflies and moths, including the dot moth, grey pug, lime-speck pug, small angle shades, and v-pug. Specialized pollinators Bees of the genus '' Macropis'' are specialized to pollinate oil-producing ''Lysimachia'' pl ...

Lysimachia × Commixta
''Lysimachia'' × ''commixta'' is a hybrid of flowering plants in the primrose family Primulaceae. It is native to eastern North America, from eastern Canada across the Great Lakes region west to Minnesota. The hybrid specific epithet ''commixta'' means "mixed together, mixed up", which presumably refers to the genetic mixing of two species. Indeed, the hybrid is sometimes referred to as the mixed loosestrife or the commingling loosestrife. Description The parents of ''Lysimachia'' × ''commixta'' are '' L. terrestris'' and '' L. thyrsiflora''. The hybrid has a terminal raceme subtended by similar lateral racemes. Vigorous individuals have additional axillary racemes up to long. Although it shows a floral morphology approaching ''L. thyrsiflora'', the hybrid is often confused with ''L. terrestris'', which also has a terminal raceme. The length of the terminal raceme, the length of its pedicel, and the length of the filaments may be used to distingui ...

Lysimachia Punctata
''Lysimachia punctata'', the dotted loosestrife, large yellow loosestrife, circle flower, or spotted loosestrife, is a flowering plant species in the family Primulaceae. Description ''Lysimachia punctata'' is a rhizomatous perennial herbaceous plant growing up to about 1.2m in height. The flowers have five petals, sepals and stamens and are produced in dense groups in the axils of leaves. The leaves are opposite and ovate. Both the leaves and the flower parts are hairy. The petals are fringed with hairs and the hairy sepals all-green, without the orange margin of L. vulgaris. Distribution It is native to SE Europe east to the Caucasus, introduced as a garden plant and widely naturalized as a garden escape An escaped plant is a cultivated plant that has escaped from agriculture, forestry or garden cultivation and has become naturalized in the wild. Usually not native to an area, escaped plants may become invasive. Therefore, escaped plants are th ... on rough ground, r ...
