Lysimachia is a genus of flowering plants. It is traditionally categorized in the family Primulaceae but should, according to Källersjö et al (2000), belong to the clade of the family Myrsinaceae.
[edit] 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.
Lysimachia species are used as food plants by the larvae of some Lepidoptera species including Dot Moth, Grey Pug, Lime-speck Pug, Small Angle Shades and The V-pug.
[edit] Species
Species within the genus include:
- Lysimachia ciliatum (Fringed loosestrife)
- Lysimachia clethroides (Gooseneck loosestrife) - A hardy perennial resembling a tall Speedwell and growing up to 3 feet (1 metre). Flowers from July on to September. Grows best in deep, rich loam in a sheltered position.
- Lysimachia nemorum (Yellow pimpernel)
- Lysimachia nummularia (Creeping Jenny or Moneywort) - Extremely hardy, and easy to cultivate; every piece of the creeping root will, if taken off, make a fresh plant.
- Lysimachia quadrifolia (Whorled loosestrife)
- Lysimachia terrestris (Swamp candles)
- Lysimachia vulgaris (Garden or Yellow loosestrife)
- Lysimachia punctata
