Care

Exposure

Install your urosperma in a sunny to partially shaded location for optimal flowering. This Mediterranean plant appreciates warm and well-ventilated spots. Avoid dense shade which would reduce flower production.

Watering

Water moderately during the growing period, allowing the soil to dry slightly between waterings. Reduce watering in winter. This plant tolerates drought well once established, a characteristic typical of Mediterranean species.

Soil

Choose well-drained, light soil that is poor to moderately fertile. Overly rich soils promote foliage at the expense of flowering. Calcareous or slightly alkaline soil suits this plant perfectly.

Fertilizing

A balanced fertilizer application in spring is generally sufficient. Avoid excess nitrogen which would encourage excessive vegetative growth. This plant doesn't require intensive fertilization.

Pruning and maintenance

Remove spent flowers regularly to encourage continuous blooming. You can lightly cut back the plant after flowering to maintain a compact shape. Remove dead or frost-damaged wood.

Diseases and pests

Urosperma is generally not very susceptible to pests. Watch for powdery mildew in conditions of excessive humidity. Ensure good air circulation and avoid stagnant moisture to prevent fungal problems.

Did you know?

Urosperma is named after the French botanist Daléchamps (16th century), a great describer of Mediterranean flora. Its characteristic yellow flowers remind one of dandelions, hence its popular nickname in certain regions. This plant was once used in traditional Mediterranean herbal medicine for its supposed diuretic properties.

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.
