Description

Heuchera 'Coral Sea' is a beautiful perennial forming a ground cover. Its evergreen reddish-orange foliage with pink reflections takes on marbled shades over time. It brightens up flower beds in light sun, partial shade, or even full shade. It produces white flower spikes in summer, which further enhances its appeal.

In recent years, heucheras have become essential plants in our gardens. Their evergreen foliage, available in multiple shades, brightens up flower beds with brilliance. These plants from the Saxifragaceae family make fantastic flower bed borders. They also perform very well in pots, allowing them to decorate even a modest terrace. Heuchera Coral Sea reaches approximately 35 cm (14 in) in height and 40 cm (16 in) in width, with its delicate inflorescences rising above its lobed foliage. The foliage, which evolves in warm shades of reddish-orange to coral-red, is a constant delight.

Heuchera Coral Sea, like many heucheras, is not very demanding when it comes to soil type, as long as it is well drained. In heavy soil, it is preferable to lighten the planting soil with sand or well-decomposed compost. It prefers partial shade or shade, but still needs some light at least in the morning to express its beautiful colours. On the other hand, it will scorch if exposed to full sun. Once established, it can tolerate occasional droughts.

You can also easily propagate it by cuttings, by taking a section of its creeping stems, which will allow you to create an entire border in just a few years. This is also a way to regenerate the clump, which sometimes tends to hollow out after 3 to 5 years of growth.

Plant this heuchera in large numbers to achieve a spectacular ground cover effect, but you can also combine it with other varieties with similar colours such as the famous 'Caramel' or 'Caribbean Sea' varieties. Conversely, you can create contrasts with dark heucheras like 'Dark Secret'. In shade, its luminous foliage will highlight the dark foliage of ferns (Dryopteris, Polystichum), Liriopes, or Ophiopogons. Finally, it can create a beautiful colour motif with shrubs such as Berberis 'Admiration'.

Planting and care

Prepare a planting hole measuring 20 cm x 20 cm x 20 cm (8 in x 8 in x 8 in). If your soil is heavy, mix some compost with the crumbled soil, partially fill the hole and place your bucket (with the pot removed) so that the top of the plant's root ball is covered with 3 cm (1 in) of soil. Adding a slow-release fertiliser (dried blood or crushed horn) will nourish your plant during its rooting period without risk of burning. Firm the soil and water generously to eliminate air pockets. If the weather is dry, you will need to water regularly for a few weeks to encourage your plant's establishment. In late winter, heucheras renew their foliage, so we recommend cutting back the previous year's leaves in January or February.
