In this post we will talk about a plant with very interesting characteristics, it is a species of the genus Helichrysum, Helichrysum cymosum.
This persistent and creeping shrub, from the Asteraceae family, comes from South Africa.
It can measure between 40 and 60 centimeters wide by 10 or 15 high; this gives us an idea that we are talking about a prostrate plant, it forms dense carpets while being highly branched. It spreads slowly thanks to its stems that root when in contact with the soil, and gradually colonizes more terrain. Simple leaves, between obovate and spatulate, silver-gray in color and with yellow flowers that appear in dense inflorescences. Flowering occurs during the months of May to June.
It is a species belonging to hardiness zone number 8, with an average annual minimum temperature range of -12.2 / -6.7°C, showing resistance to strong frosts, which means we can plant it anywhere in our latitudes, since it is also indifferent to the type of soil, whether calcareous or siliceous. It also tolerates substrates poor in nutrients and prefers those that contain good water drainage. It is also suitable for rock garden areas both inland and coastal, as it likes rocky and sandy terrains, apart from being tolerant to salinity and sea breeze.
Helichrysum cymosum has proven to be a very drought-tolerant species. It only requires support irrigation during the 8-10 weeks after planting, once well rooted it does not require any irrigation (except those planted in pots). With this species it is not necessary to apply mulch materials such as bark or other inorganic materials, since being prostrate, it prevents the appearance of weeds and retains a certain constant moisture level in the soil.

Its preferred location is in full sun, where it will perfectly develop its characteristics, suitable in sustainable gardens since its water requirements are very low.
The recommended planting density is 2 to 3 plants per m2. This low planting density is due to its rapid colonization and growth capacity. Thus it is a great plant for slope restoration or to quickly cover extensions of gardens or parks, both public and private. It is also interesting not only for its flowering but for the color of its leaves, which make it suitable year-round. It can also be used in borders and also planted in pots.
It is a highly recommendable and versatile plant that we encourage you to try, and it will surely give you very satisfactory results in your gardens.
