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.

I've ordered a few things from Big Plant Nursery even with delivery costs it still works out cheaper than my local nursery. Really big, healthy ceanothus and it has put on new growth already (in middle of Feb) having only been in the ground a few weeks. Highly recommended
