Rhaphithamnus spinosus

From Chile and Argentina, this is grown for the small tubular pale-blue flowers in April and especially the deep-purple-blue round fruits in autumn. This would appear to be a myrtle from afar, but under close inspection one sees the small sharply toothed leaves are subtended by sharp spines. A medium to large evergreen shrub, best against a warm wall in colder areas. Flaking beige bark.
