Its habitat is that of swamps, streams and in shallow water in reed marshes, shady places near the water, where it avoids acid soils and is present in most wetlands, but usually in tall grass woods, on the edge of the scrub or the woods or even in the reeds of Phragmites.

Description –
Lysimachia vulgaris is a perennial herbaceous plant with an erect habit, 50-150 centimeters high which develops from a rhizome.
The leaves are opposite, ovate to lanceolate in shape and speckled with translucent orange glands.

The plant blooms from June to August.
The fruit is a septic capsule, globose of about 4 mm, ± bright, brown or reddish. Nymeric seeds, laterally compressed, oblong, about 1,5 mm, trine, wrinkled, light brown in color.

Cultivation –
Lysimachia vulgaris is a plant that in its natural state spreads through rhizomes, forming large patches and is sometimes considered invasive outside its original range.
It is an easy to grow plant that grows well in moist or wet clay soils with sun exposure or partial shade although it prefers a shady location.
The plant resists up to at least -25 ° C.
Propagation occurs by seed with sowing to be carried out in spring or autumn in a cold greenhouse. Seedlings can be transplanted when they are large enough to be handled and placed in individual pots or in open field in mid-spring.
The plant can also multiply through tufts, taking the larger ones and replanting them directly in their permanent positions, although it is better to pot the smaller tufts and grow them in a cold greenhouse until they root well. The plant is always in spring.
Basal cuttings can also be obtained, in the period from early spring to mid-spring. In this case the shoots with abundant underground stem are collected when they are about 8 – 10 cm from the ground. These should be placed in individual pots, kept in the shade in a cooler area or in a cold greenhouse until they root well. The transplant must be done in mid-spring.
