Maltese cliff orache is a rare, evergreen, woody shrub found only on sheer limestone cliffs in Malta and Gozo. It is grown mainly by specialist collectors and botanic gardens, and it needs free-draining soil, full sun and very little water.

About
Atriplex lanfrancoi, also known as the Maltese cliff orache, is a species of plant in the family Amaranthaceae. It is perennial, evergreen, branched, woody shrub. It is endemic to Malta, where it is found on sheer cliffs along the coasts of the islands of Malta and Gozo. It never occurs further than 100 m from the cliffside. The Maltese cliff orache is listed as being endangered on the IUCN Red List. It was formerly assessed as being critically endangered. The species has a very restricted and fragmented range and its preferred habitat is threatened by natural erosion, limestone quarrying, and pollution caused by waste dumping. Its wild population is expected to number in the several thousands and is thought to be declining.
Where it grows
The Maltese cliff orache is endemic to Malta, where it is found on sheer cliffs along the southern and southwestern coasts of the island of Malta, as well the western and northwestern coasts of Gozo and on Fungus Rock. It prefers the lower parts of limestone cliffs and is occasionally found on plateaus along the tops of cliffs, but never occurs further than 100 m from the cliffside.
