Ruta angustifolia Narrow-leaved Rue
I believe I am correct in the identification. This sub-shrub can grow from 20-80cms tall and is native to the Mediterranean and SW Asia. It can be used as an insect repellent and anti-spasmodic. It must not be applied to the skin during sunlight hours as the oils may cause blistering. if used medicinally. The leaves have a grey-blue tinge and it flowers from April to July.
