Description
It belongs to the primrose family (Primulaceae). In Poland it grows in the south-east, in rather damp places. It has short underground runners and upright, hairy, angular, sparsely branched stems. In favourable conditions it grows lushly, flowers profusely and spreads vigorously, reaching about 100 cm, though on average it grows to 60 cm. The variety 'Variegata' has egg-shaped or lance-shaped, white-edged leaves about 7 cm long, set in whorls along the whole stem. Yellow flowers about 2 cm across grow several at a time from the axils of the upper leaves, forming long, leafy racemes. The petals are covered with fine glandular hairs. It flowers long – from June to August – and profusely. Lysimachia punctata is one of the most important perennials for naturalistic gardens and is also suitable for borders. It is frost-hardy and long-lived.
Requirements
It does equally well in sun and in shaded positions, provided the soil is fertile – ideally loamy or clayey – and moderately moist to moist.
Propagation
Dotted loosestrife is propagated by dividing larger clumps in spring or autumn. It is a fairly invasive plant and spreads quickly.
