Ceanothus 'Trewithen Blue', the California Lilac, a wonderful small evergreen tree which is covered in masses of pale blue flowers in early summer. It is tolerant of exposed and coastal conditions as long as it is in full sun. Little maintenance is required except a light trim once the flowers have faded. Thus makes an excellent all-rounder for the smaller garden. RHS Award of Garden Merit.
