Eulychnia castanea

A low, creeping Eulychnia with grass-green stems 1 to 2 m long lying along the ground and forming thickets several metres across, about 50 cm tall. It grows on the fog-bathed Pacific coast of central-northern Chile, so it likes mild temperatures, full sun, moist air and a mostly dry, gritty root zone.
