Halimium calycinum, commonly known as Sun Rose, is an evergreen shrub native to the sandy coastal areas, scrublands, and rocky outcrops of the Western Mediterranean, including Portugal and Spain. It typically grows to a height and width of 2-3 feet (0.6-0.9 meters), forming a low, bushy mound. The plant is characterized by its silvery-green foliage and bright yellow, saucer-shaped flowers that bloom profusely in the summer and fall, adding a splash of color to the garden. The flowers are particularly showy, with a dark maroon central blotch that contrasts with the yellow petals.

Sun Rose is valued for its drought tolerance and ability to thrive in poor, well-drained soils, making it an excellent choice for xeriscaping and Mediterranean-style gardens. It is often used as a ground cover, in rock gardens, or as part of a border planting due to its compact size and attractive blooms. For optimal flowering, it should be planted in a location with full sun exposure. While generally low-maintenance, Halimium calycinum can be susceptible to fungal diseases in humid conditions. Pruning after flowering can help maintain its shape and promote vigorous growth.CC BY-SA 4.0
