Linnaea are hardy perennial subshrubs that are native to woodlands.
They have small evergreen leaves and carry pink or white fragrant bell shaped twin flowers from the end of spring through to the early summer.
They are ideal plants to grow in a shady part of a rock garden.
A common name for the Linnaea plant is Twin Flowers / Twinflower.

It is best to grow twin flowers outdoors from seeds. They should be sown into flats in a shaded part of the garden and covered in glass.
It can take a very long time (years) for Linnaea plants to germinate, so it may be better to buy plants from a garden center (Twin Flowers are easier to propagate from established plants).
If/when you manage to get the Linnaea plant seedlings to grow in a flat, then transplant them in either spring or summer into a shady part of the garden, that has a peaty wood soil and is very acidic (pH 4 to 5) that is moist. Space out at 30 cm (12 inches) apart.
Once growing it is important to ensure that twin flowers always have moist soil to grow in, so water frequently to stop from drying out.
If you require more plants then Linnaea can be divided in the spring or root cuttings can be took.
