The Hypericum

There are many plants belonging to the genus of the Hypericus; they are mostly small herbaceous perennials, but there are also small evergreen or deciduous shrubs; many species and varieties are used as ornamental plants, although most species exhibit the same beneficial characteristics as the officinal plant. The officinal species is called Hypericum perforatum, a perennial herbaceous plant, evergreen in areas with a mild winter climate; the foliage appears pierced, as the leaf lamina is covered with small translucent vesicles. During late spring it produces small golden-colored flowers, typical of the hypericum and flowering lasts a few weeks. All species of hypericum produce star-shaped flowers, some continue to bloom throughout the summer, these flowers are the main reason why the hypericum is so successful as a garden plant.


The hypericum plants prefer rather sunny positions in places where the summer season is mild and the half-shade positions in the territories where the summers are very hot and sultry. It is a plant that does not fear the cold of the winter season and for this reason, its cultivation is possible even in those areas characterized by rather difficult climates.
As far as irrigation is concerned, hypericum seedlings are generally satisfied with rainwater. If you find yourself in hot and dry months, when weeks of drought are occurring without rainy days, you should water St. John's wort regularly.

Soil and fertilization

The Hypericum grows well in any type of soil. The important thing is that it appears loose and well drained. Fertilization should be carried out at the beginning of spring when the plant is preparing for vegetative growth.
The fertilizer must be slow-release or with mature manure. If we wish to reproduce our Hypericum, it is good to know that the multiplication can take place by semi-woody cutting, by sowing or by dividing the tufts thanks to the stolons that grow from the mother plant. To carry out sowing it is good to wait for the months of September, October and November.
