Description
Lysimachia punctata is a perennial herbaceous plant with upright stems and bright yellow flower clusters that appear from June to August. Native to southeastern Europe, it is a long‑established garden perennial that thrives in damp, partially shaded corners. The plant produces underground runners and can spread vigorously over time, so it is advisable to plant it in a clearly defined bed or with a rhizome barrier from the start. It provides reliable nectar for bees and bumblebees during its flowering period and is a low‑maintenance, robust plant suitable for naturalistic beds near ponds or in moist garden areas.
Care instructions
Plant in spring, around mid‑April (week 16), in a site ranging from partial shade to full sun with consistently moist soil. Water regularly during dry summer weeks, especially in full‑sun locations, to prevent leaf wilting. Because the plant spreads via runners, prune excess shoots at the edge in autumn or early spring to keep its spread in check. After flowering, cut back spent stems close to the ground to encourage compact growth the following year. Divide the plant every three to four years; this also provides new plants for other beds.

Soil & site
Soil pH
Soil type
moist, humus-rich, nutrient-rich, well-drained
The dotted loosestrife likes it evenly moist to fresh; it tolerates both waterlogged and completely dry soils poorly in the long run. A humus-rich, nutrient-rich garden soil is quite enough for it, it is not fussy about pH and grows from slightly acidic to slightly alkaline. It feels most at home at the pond edge or in partial shade under trees and shrubs, where the soil never dries out completely.
Feeding
Medium feeder
Months
Apr, Jun
A spring application of mature compost in April usually supplies the dotted loosestrife sufficiently for the season. If you top up again in June with diluted nettle feed, you support strong new growth after a first cutting back. This robust perennial needs nothing more; overly generous feeding mainly encourages its already pronounced urge to spread.
Overwintering
The dotted loosestrife is easily hardy in Central Europe and needs no protection at all. The foliage above ground dies back in autumn, and the roots survive safely in the soil. You can leave the wilted stems standing in autumn or cut them just above the ground in early spring before new growth begins.
Propagation
Methods
- Division
- Cuttings
The easiest way to propagate the dotted loosestrife is by division in spring or autumn; the strong rhizomes can be split up easily with a spade. Each piece with a few shoots and some roots keeps growing reliably. Alternatively, tip cuttings in early summer also work and root quickly in moist soil. Since the species wanders on its own by runners, you will often find ready-made young plants in the bed to move.
