Hypericum is commonly known as St John's wort and also Rose of Sharon. Most varieties are deciduous or semi-evergreen and summer flowering with lovely bright yellow flowers and followed, in autumn, by attractive berries. There are many varieties but those commonly sold and grown in gardens are H.x hidcoteense 'Hidcote' and H. calycinum 'Brigadoon'.
Before planting Hypericum, be aware that all parts are toxic to animals and should be handled carefully as contact with the leaves can cause skin irritation. That said, Hypericum is easy to grow and is tolerant of most growing conditions. Hypericum will put up with drought and shade, (although flowers best in sun) but dislikes waterlogged soils. Hypericum has a long flowering season and carries a profusion of blooms as the image top right illustrates.
It is vigorous with a tendency to self seed, and is considered by some to be invasive because of its self seeding.
There is no requirement to prune other than to remove any dead wood in the spring.
There are also dwarf varieties suitable for front of the border or rock gardens such as Pallens.
Another plus point of Hypericum is that it is ideal to have as a cut flower both the blooms and later the berries are attractive and frequently used in flower arrangements.
