Description

Brilliant crimson flowers smother this sun-loving shrub in a dazzling display of colour. Helianthemum 'Supreme' is a compact evergreen rock rose covered in vivid crimson blooms with yellow centres that open freely through late spring and summer above neat grey-green foliage. The cheerful flowers create a carpet of colour that spills beautifully over walls, edging and gravel gardens, bringing brightness and texture to sunny planting schemes. Its low-growing habit makes it ideal for rockeries and containers, where the evergreen foliage continues to provide interest long after flowering has finished. Despite its delicate appearance, this variety is remarkably resilient and thrives in exposed locations, making it a dependable choice for coastal gardens and dry borders alike. Compact, colourful and easy-going, it delivers masses of vibrant blooms with very little fuss. Ultimate height: 20cm (8in). Ultimate spread: 40cm (16in).

Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only.

How to Grow
Plant rock roses into moderately fertile, neutral or alkaline soil, in full sun. Helianthemum dislike wet ground, particularly during winter. Improve heavy soil conditions by adding coarse grit or sharp sand prior to planting. Once established, rock roses can easily tolerate dry sandy soils.

For more information and guidance check out our Gardening Guides.

More Info
Feed and water regularly throughout the growing season while young plants become established. Once established, rock roses are relatively drought tolerant and require minimal maintenance. After flowering, prune helianthemum stems back to within 3cm (1”) of the previous year’s growth.
