Details
Create a stunning warm glow in your sunny borders and gravel gardens with Helianthemum 'Bronze Carpet' (Rock Rose). This vigorous, spreading evergreen alpine forms a neat mat of dark green foliage that is absolutely smothered in papery, coppery-orange blooms throughout early to mid-summer. Highly drought-tolerant once established, it is a fantastic, low-maintenance choice for ground cover on dry banks, rockeries, or cascading gracefully over low walls.

Bedwen Plants Care Tip: Like all rock roses, 'Bronze Carpet' requires excellent drainage and a spot in full sun to thrive. To maintain a compact, bushy habit and encourage vigorous fresh growth, trim the plant lightly with shears straight after its main flush of flowers has faded, ensuring you do not cut back into old, bare wood.

Plant Care
What are you buying?
4L, 2L & 1L refer to pot volume in litres. 9cm, 7cm & 5cm refer to pot diameter. These are common terms used in plant retail to indicate the size of a plant root system. Leaf & stem growth on plants varies widely by variety and time of year. Usually, 1L/2L/4L plants can be anywhere between 20-60cm tall & 5/7/9cm plants will be around 10-30cm tall. However, this may be less if the plant is naturally low growing or if it is a herbaceous plant in winter.
Plug plants are small plants grown from seeds or cuttings in cell trays. Their root systems start from about 1cm and the largest plug plants, described as extra-large or jumbo, are usually around 4cm. Plug plants can be great value to buy but they will need some extra care to get them started. We recommend planting each plug plant into its own 7 or 9cm pot (about the size of a standard mug), NOT directly into open ground or large pots. Ensure the pot has plenty of holes underneath and preferably over two tiers for even better drainage.
