Members of the Lysimachia plant genus are usually upright hardy perennials that usually reach from 30 to 90 cm (1 to 3 feet) in height. Some species however, are low growing, and can reach only 7 cm (3 inches) in height.
Lysimachia have lance or rounded shaped leaves. They bloom in the summer.
Depending on the individual species of Lysimachia, there is much variation in the flower type: ranging from small stellar shaped yellow flowers through to clusters of white flowers.

It is best to start growing Creeping Jenny and other Lysimachia outdoors from seeds in flats.
Sow the seed on the surface in the autumn. Next, sink the flat into a completely shaded part of the garden, and cover with glass.
It should take from one to three months for Lysimachia Creeping Jenny to germinate.
Once the seedlings of Lysimachia have grown large enough that they are beginning to trail, they can be transplanted into either a partially shaded or sunny part of the garden.
It is best to space Creeping Lysimachia species about 50 cm (20 inches) apart. They prefer to grow in a moist soil.
Once growing, Creeping Jenny pretty much looks after itself, so long as the soil is moist. In fact you may need to control it to stop it taking over the garden!
In the autumn Lysimachia species should be cut back to ground level.
If you do require to propagate more plants, then they should be divided in the spring in cold areas or in the summer in warmer areas.
