Lysimachia punctata (Yellow Loosestrife)

Yellow Loosestrife, Whorled Loosestrife, Garden Loosestrife, Dotted Loosestrife


Named after the Macedonian King of Thrace (Lysimachus), Lysimacha punctata (Yellow Loosestrife) is a perennial plant with great ornamental value, producing sturdy, upright stems loaded with abundant spikes of cup-shaped, golden yellow flowers, tinged with red at their heart. Blooming for weeks from late spring to late summer, the flowers rise above whorls of light green serrated leaves.

  • Native to central Europe and Turkey, this plant is easy to grow and excellent at providing fast-spreading cover when required, creating great visual impact. However, attention should be paid to controlling its spread as this plant tends to be invasive.
  • Vigorous, this rhizomatous perennial reaches 36 in. in height (90 cm) and 12-18 in. across (30-45 cm). Undemanding, Lysimachia punctata spreads by rhizomes and self-seeds in optimum growing conditions to form large colonies. However, it will spread more slowly if grown in partially shaded sites.
  • Performs best in full sun or part shade, in humusy, moist, well-drained soils. This plant will require partial to full shade in hot summer areas. Drier soils are tolerated in partial shade.
  • A perfect plant for cottage gardens, wild gardens, bog gardens or next to ponds and streams. Excellent as long-lasting cut flowers!
  • A popular variety is Lysimachia punctata 'Alexander' with its striking variegated foliage, lime green with bright creamy edges, and loads of golden yellow flowers.
  • Yellow Loosestrife is generally not subject to serious pest or disease issues. Watch for rust and leaf spots.
  • Should be monitored to avoid undesired spread. Plants should be divided every 2 or 3 years, in the spring or fall, to control their growth.
  • There are up to 180 species of Lysimachia. The genus includes hardy to frost-tender perennials, either herbaceous or evergreen. Their habit can be upright or prostrate, with some forming excellent ground covers. Their flowers are variably shaped, are usually yellow or white, but sometimes pink or purple. Many species are invasive, but this tendency can be harnessed to produce large stands, creating greater visual impact.
  • Contact may cause skin irritation or an allergic reaction.
