Key information

Description

A vigorous, evergreen perennial ornamental plant with a characteristic semi-recumbent or ground cover habit that makes it ideal for creating dense, colourful carpet-like ground cover where a multitude of brightly coloured, daisy-like flowers emerge from between the characteristic fleshy cylindrical leaves. It is mainly used to decorate flower beds and rock gardens but also pots and planters. Very hardy, it tolerates hot and dry climates. It requires no special cultivation care.

Varietal description

Plant suitable for rock gardens in warm temperate climates. Carpeting, with abundant and showy flowering in late spring and summer.

Origin and History

curiosity and special features

The elongated, fleshy-looking leaves store water, making the plant resistant to periods of drought. In addition, the foliage is covered with transparent scales resembling tiny pieces of ice, hence the common name in the Anglo-Saxon world, 'Ice plant'.

Origin and Diffusion

A species native to the rocky areas of southern and eastern Africa, it was discovered in the 1800s by Thomas Cooper, a botanist who set out for South Africa in 1859 on a commission from succulent collector W. W. Saunders and from whom the epithet cooperi is derived; today it is widespread throughout Europe as an ornamental plant.

soil preparation

Before transplanting in mid-spring, carry out light digging and remove any weeds and bulky stones; also break up coarser clods to give greater softness. If the soil is too compact, it is advisable to bury sand. Finally, distribute professional substrate on the surface for approx. 5/10 cm and carefully level out by preparing the planting holes according to a suitable density.

Cures and Adversities

planting

For use in flowerbeds, we recommend an average density of 15 plants per square metre in order to ensure proper development of each specimen, resulting in well-proportioned final compositions. We also suggest not sinking the lump of each plant completely, keeping it moist but not saturated with water to avoid root and collar rot.

Reproduction/Propagation

Mainly by apical and node cuttings.

Irrigation

Use rainwater, alternatively canal water, manually or by irrigation system. After transplanting, assist the seedling by avoiding desiccation and maintaining a constant humidity at the new planting site. Afterwards, allow the soil or substrate to dry out slightly, always checking the moisture level before watering; it is also suggested not to water the plant from above during the evening hours to prevent the development of phytopathologies.

Fertilization

After planting in the new planting site, during the spring-summer period, apply a balanced liquid fertiliser specifically for ornamental plants to the soil or substrate, to be diluted in the irrigation water in appropriate doses and frequencies as stated on the relevant information label.
