Description

 

The Lithodora diffusa ‘Heavenly Blue’ is a genus from the Boraginaceae family and also commonly known as purple gromwell. The Lithodora diffusa is native to the southwest of Europe and the northern part of Africa. The Ancient Greek term lithodora literally means stone gift, presumably referring to its preferred habitat. Diffusa is Latin and means loosely spreading which refers to the plant's growth habit.

The purple gromwell prefers acidic and well-drained soil and a sunny and sheltered position. In late spring the Lithodora diffusa ‘Heavenly Blue’ produces intense blue flowers. The purple gromwell gradually spreads but is easy to restrain. You can cut or pull away the parts where you do not want them

The Lithodora diffusa ‘Heavenly Blue’ has dark green sturdy hairy leaves. The purple gromwell is ideal for a rock garden along the edges of your border or as groundcover. The Lithodora diffusa ‘Heavenly Blue’ is drought and salt tolerant.
