Care
Exposure
Install Coronidium scorpioides in full sun, with a minimum of 6 hours of direct sunlight daily. This sun-loving plant develops better and flowers more generously in a well-exposed location. Avoid partial shade which would slow its growth.
Soil and drainage
Prefer well-drained, light and poor to moderate soil. A sandy or gravelly substrate works perfectly. This species dreads stagnant moisture and root suffocation. Improve if necessary with sand or gravel.
Watering
Water moderately during the growth period, letting the soil dry out slightly between waterings. Reduce watering significantly in winter or if the plant is dormant. Avoid excess water which promotes root rot.
Fertilizing
Apply diluted balanced fertilizer every 15 days during flowering. This undemanding herbaceous plant is satisfied with soil of moderate fertility. Excessive fertilizing can reduce compactness and flowering.
Pruning and maintenance
Pinch young plants regularly in spring to encourage dense branching. Remove faded flowers to extend flowering. At the end of the season, cut back the plant or let it regenerate naturally.
Diseases and pests
Watch for root rot in case of excess moisture. Aphids and whiteflies can affect weakened plants. Ensure good ventilation and treat any detected pest outbreak quickly.
Did you know?
The name Coronidium evokes the crown (corona in Latin), while scorpioides refers to the curved shape of its flower heads, reminiscent of a scorpion's tail. This small Mediterranean herbaceous plant was once appreciated in botanical gardens for its distinct morphological curiosity within the Asteraceae family.
Where to buy it
Plant in spring or early autumn, avoiding spells of intense heat. Pick a plant with healthy foliage and roots that are not exposed. Best time: March, April, May, September.
