They are evergreen shrubs with a creeping bearing that spread horizontally through stolons and do not exceed 45 cm (17.71") in height. The leaves are opposite, leathery, ovate-elliptical in shape and deep green in color. The showy flowers are yellow and have numerous threadlike stamens. They bloom in summer.

They are used as isolated specimens, in bushy groups, to cover slopes and low walls and in undergrowth. They are ideal for Mediterranean coastal gardens and for cities.

Hypericum calycinum can grow in full sun, semi-shade and shade exposures. They resist non-persistent frosts.

They prefer a light soil, well drained and containing organic matter but they also grow in poor or calcareous soils.

Water moderately, waiting for the substrate to dry; greatly reduce watering in winter.

Fertilize with compost in autumn and with mineral fertilizer every 30 days in summer.

Prune intensively in autumn to strengthen the plant and control its lateral expansion.

They are shrubs resistant to the usual pests and diseases.

They are propagated by cuttings in summer, by division in fall and from seed sown in spring.
