The plant has a slender flexible woody stem that produces small white flowers during May and June.

The population is usually divided into small fragments, with the exception of a 1.5km stretch between Rdum Dikkiena and San Ġorġ tal-Fawwara.

The population's strict rock-dwelling habitat is gradually decreasing due to natural causes like erosion, landslides, and cliff collapses.

It is found growing on rocky outcrops and sea cliffs where there is little soil and water, and where other plants struggle to survive.

The plant is threatened by a number of factors, including habitat destruction and degradation due to urbanisation and quarrying activities.
