Extremely widespread succulent throughout the European continent, thanks to its ability to grow spontaneously in rock gardens or walls. It does not reach heights greater than 15-20 cm, but rather tends to develop horizontally occupying large spaces, which is why it is widely used as a ground cover on any type of soil. It has sprawling stems along which fleshy, rather small and pointed leaves of a nice dull green grow. In summer, its small yellow flowers give it a touch of liveliness. It is a really simple plant to grow because it adapts to any soil and, most importantly, resists well at any temperature, but that's not all: its leaves are believed to be edible and their juice has soothing properties!
