About this plant
A solid shrub that has good-sized green leaves that are held in pairs on the stems. The shrub is valued for its yellow flowers that open as goblets, then spread their petals wide to reveal long curving stamens that surround the developing berry. The shrub flowers in July and August and there may be a few more flowers in autumn. The flowers are followed, or may be combined with, shiny light red fruits that eventually turn black. A good-sized shrub that could make a valuable contribution to background planting in the garden. Note: This is one of a range of useful compact shrubs that have been bred to resist the 'rust' disease that afflicted many hypericums.

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 to keep the soil moist
For best results, this plant needs soil that is always moist. Water deeply and regularly as soon as soil appears dry. Even for established plants in the ground, a dry week can cause problems with some soils. Check plants in pots more often, especially in hot weather. Or install an automatic irrigation system which will do the hard work for you, even when you are away on holiday.
Without regular watering some plants never fully regain their beauty.
Planting & general
Outdoor planting · Planting
Add root growth stimulant to the planting hole
Mycorrhizal fungi helps roots establish quickly, so they absorb water and nutrients more efficiently. It comes as a powder, granule or gel. Add to the planting hole or container, and to the plant's rootball before planting in the hole. For "bareroot" plants use a gel.
