About this plant
This is a shrub for a warm wall. It mainly flowers in mid-spring but produces flowers in winter at mild times. The flowers are pleasantly and sweetly fragrant. It makes a hearty shrub and can present an informal aspect with rather wayward branches. It looks spectacular when every stem is covered in golden blossom. It needs protection from cold to thrive.

Spring
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.
Spring - early · Planting
Prune new growth
Prune in early spring being careful only to prune wood that has been grown in the previous season of growth. Dead branches and misplaced or awkward branches can be removed in their entirety.
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.
