Halimium lasianthum, commonly known as Lisbon False Sun-Rose, is an evergreen shrub native to the coastal scrub and dry woodlands of the Iberian Peninsula. It typically grows to 1 m (3 ft) tall by 1.5 m (5 ft) wide. The plant has a compact, bushy form with grey-green, lance-shaped leaves that provide a textured backdrop for its flowers. The bright yellow, saucer-shaped flowers bloom in spring and are quite showy, often featuring a distinctive maroon blotch at the base of each petal, which adds to its ornamental value.

Lisbon False Sun-Rose is valued for its drought tolerance and vibrant springtime flowers, making it a suitable choice for rock gardens, Mediterranean-style landscapes, and coastal plantings. It thrives in full sun, requiring low amounts of water once established, and prefers sandy, well-drained soils. While it is generally low-maintenance, it may benefit from light pruning to maintain its shape and promote denser growth. This plant is not known for significant disease or pest issues, but it can be sensitive to overwatering and poor drainage.CC BY-SA 4.0
