Saxifraga callosa aka Limestone Saxifrage

Saxifraga callosa, also known as the limestone saxifrage, is a rare evergreen perennial plant in the family Saxifragaceae. Native to maritime alpine habitats in Western Europe, including Italy, France, and Spain, this species grows up to 50 cm tall and 100 cm broad. It forms clumps of rosettes with narrow grey-green leaves that are coated in lime. In spring, it produces starry, pure white flowers in long panicles. The Latin specific epithet callosa refers to its thick-skinned nature with calluses. This plant is an excellent choice for houseplant enthusiasts, as it can thrive indoors with regular watering. It prefers abundant sunlight and should be positioned less than 3 feet away from a window. To ensure its optimal growth, it is important to use well-draining soil. Additionally, regular repotting is recommended, ideally when the plant doubles in size, which eliminates the need for added fertilizers. With its unique characteristics and striking appearance, the limestone saxifrage is a captivating addition to any indoor garden.
