Santolina rosmarinifolia explained

Santolina rosmarinifolia, the holy flax,^[1] is a species of flowering plant in the daisy family Asteraceae, native to south western Europe. It is a dense, compact evergreen shrub growing to 60cm (20inches) tall and wide, with narrow, aromatic green leaves and tight yellow composite flowerheads carried on slender stalks above the foliage, in summer.^[2]

The Latin specific epithet rosmarinifolia describes the leaves' passing resemblance to those of rosemary.^[3]

In cultivation it is useful as groundcover or as an edging plant for sunny, well-drained situations. It dislikes winter wetness, and can be short-lived. The cultivar ‘Lemon Fizz’^[4] and the dwarf cultivar S. rosmarinifolia subsp. rosmarinifolia 'Primrose Gem'^[5] have gained the Royal Horticultural Society's Award of Garden Merit.^[6]

Also known as olive herb or Wadi tops, the leaves of S. rosmarinifolia can be used in Mediterranean dishes and cocktails to add an olive-like flavour.^[7]
