Cupressus lusitanica (Mexican Cypress, Cedar of Goa)


Michael's Opinion

This splendid aromatic evergreen retains its appeal through the year with its pendulous branches covered in dense glaucous blue to dark green foliage which cascades over its short trunk. Perfect for screening or as a windbreak.
