About this plant
Popular shrubs that come in a wide range of forms, but having common ground with their yellow flowers. These can be showy with large shiny blooms that have long stamens at their heart, making them appear distinctly exotic. There are exquisite dwarf forms at home in the rock garden, some useful ground covering forms (the Rose of Sharon Hypericum calycinum), and modest native forms that could naturalize in a wild garden. The native forms include the Tutsan (Hypericum androsaemum) which has cultivars with intriguing variegations and leaf colours. Finally there are the showy hybrids whose end of season flowers coexist with enticing coloured fruits that shout 'buy me', and which are almost irresistible in autumn.; Hazardous: Hypericum perforatum is harmful if eaten.

Spring
Spring - late · Outdoors
Feed with slow release fertiliser
Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)
This is a simple way to provide a nutrient boost as a single annual procedure.
Spring-Autumn · Outdoors
Water in dry periods
Established plants in the ground can cope with 7-10 days of dryness, and shrubs often manage 2 to 3 weeks. Water one section of the garden thoroughly each day rather than a little everywhere. Check plants in pots more often, especially in hot weather.
