About this plant
This makes a mounded shrub, much larger in the wild than when cultivated. It has small bluish green leaves, close packed on the stems. The five petalled flowers appear in late summer. They are coloured light yellow and open out with wavy petals, rather flat in appearance. A columnar cluster of stamens at their heart. It is ideally suited to a rock garden, enjoying a well drained sunny spot. It can be cut to the base by hard winter frosts but will generally regenerate from the base during the spring. It should reach around 30cm (12in) in height with a 50cm (20in) spread.

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.
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.
