Description
Hypericum perforatum, also known as Perforate St John's wort, Common St John's wort, or Official St John's wort, is a beautiful perennial used in homeopathy for its calming and soothing virtues. It is a robust plant with wild charm that is appreciated in the garden for its long and abundant golden-yellow flowering, and also for its undemanding nature. Very hardy, it is perfect in a wild garden, in neglected areas, or in sunny spots.
Hypericum perforatum belongs to the Hypericaceae family. This plant is present throughout Europe, Asia, North Africa, and North America. In nature, it grows in the sun on limestone soils: along paths, at the edge of forests, in meadows, and on dry slopes. It is a perennial with a woody stump related to the shrubby St John's worts. The plant has a woody underground stem. It quickly forms a tuft 50cm (20in) to 1m (3ft) high (depending on growing conditions) and about 60cm (24in) wide. It can spread in large colonies. Its aerial vegetation is deciduous. It dries in autumn and reforms in spring. Its elliptical or linear leaves of a dark green shade are dotted with small translucent spots that contain an essential oil, and their border shows small black spots containing an active principle, hypericin, responsible for the properties of the plant. Abundant flowering takes place from May to September. It takes the form of large panicles bearing flowers of 3.5cm (1in) with 5 bright yellow petals marked with black. The heart of the flower is occupied by a bouquet of long stamens. After pollination by insects, red fruits form in the shape of ovate capsules.
Hypericum perforatum is a great plant for difficult, little watered, even very dry areas, naturalistic beds, and gardens that leave a place for nature. Plant it on a large sunny slope, along the border of a path, on the sunny edge of a dry underwood, ot at the foot of a hedge. To accompany it, consider for example easy annuals like Love-in-a-Mist, Buglosses, or Persian Cornflower.
Although medicinal, St John's wort should not be consumed.

Planting and care
Plant in any type of soil: light or clayey, moist, dry in summer, and even limestone. It perfectly tolerates summer drought and does without watering, but will show more flowers with a water supply in summer. It thrives in full sun, where it is more floriferous, but adapts perfectly to partial shade. Control its lateral growth by eliminating the shoots that develop on the periphery of the clump. Pruning the faded flowers prevents spontaneous sowing.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
The flowering period indicated on our website applies to countries and regions located in USDA zone 8 (France, the United Kingdom, Ireland, the Netherlands, etc.)
It will vary according to where you live:- In zones 9 to 10 (Italy, Spain, Greece, etc.), flowering will occur about 2 to 4 weeks earlier.
- In zones 6 to 7 (Germany, Poland, Slovenia, and lower mountainous regions), flowering will be delayed by 2 to 3 weeks.
- In zone 5 (Central Europe, Scandinavia), blooming will be delayed by 3 to 5 weeks.
In temperate climates, pruning of spring-flowering shrubs (forsythia, spireas, etc.) should be done just after flowering.
Pruning of summer-flowering shrubs (Indian Lilac, Perovskia, etc.) can be done in winter or spring.
In cold regions as well as with frost-sensitive plants, avoid pruning too early when severe frosts may still occur.
The planting period indicated on our website applies to countries and regions located in USDA zone 8 (France, United Kingdom, Ireland, Netherlands).
It will vary according to where you live:
- In Mediterranean zones (Marseille, Madrid, Milan, etc.), autumn and winter are the best planting periods.
- In continental zones (Strasbourg, Munich, Vienna, etc.), delay planting by 2 to 3 weeks in spring and bring it forward by 2 to 4 weeks in autumn.
- In mountainous regions (the Alps, Pyrenees, Carpathians, etc.), it is best to plant in late spring (May-June) or late summer (August-September).
The harvesting period indicated on our website applies to countries and regions in USDA zone 8 (France, England, Ireland, the Netherlands).
In colder areas (Scandinavia, Poland, Austria...) fruit and vegetable harvests are likely to be delayed by 3-4 weeks.
In warmer areas (Italy, Spain, Greece, etc.), harvesting will probably take place earlier, depending on weather conditions.
The sowing periods indicated on our website apply to countries and regions within USDA Zone 8 (France, UK, Ireland, Netherlands).
In colder areas (Scandinavia, Poland, Austria...), delay any outdoor sowing by 3-4 weeks, or sow under glass.
