Koromiko
Veronica salicifolia
Koromiko (Veronica salicifolia, formerly Hebe salicifolia, the name Plants For A Future and many nurseries still use) is a bushy evergreen shrub with upright branches, native to New Zealand's South Island, Stewart Island and the subantarctic Auckland Islands and, disjunctly, to southern Chile. It carries narrow, willow-like, lance-shaped leaves up to 5 inches long year-round and, in summer, dense spikes up to 8 inches long of tiny white to pale lilac flowers that bees work readily. Sources disagree on how large it gets: RHS gives an ultimate height and spread of 5 to 8 feet, reached in 5-10 years, while Plants For A Future documents plants to 14 feet by 9 feet, so give it room rather than assuming the smaller figure. It is frost hardy rather than fully cold hardy: RHS rates it H5, hardy to about 5°F, so Plotwright publishes zones 7b-9b rather than the 6a cold edge in Plants For A Future's hardiness listing. It is very wind resistant and tolerates maritime exposure and atmospheric pollution, which makes it a dependable shelter hedge for coastal, cottage and wildlife gardens, though Plants For A Future calls it intolerant of drought while RHS marks it drought resistant, a genuine disagreement worth knowing before you skip watering. It has no known edible uses and Plants For A Future lists no known hazards; Maori traditionally chewed the leaves to help cure diarrhea and applied them to the skin for ulcers and wounds.
