Westringia ‘BLUE GEM™’ is a compact Australian native hybrid of Coastal Rosemary, bred for its dense form and extended flowering performance. It forms a neat, upright shrub with narrow olive-green foliage held on contrasting dark stems, giving it a refined, structured appearance in the landscape
Its standout feature is the abundant display of vibrant blue to violet flowers, which appear heavily in spring and continue intermittently throughout much of the year. This long flowering period, combined with its toughness, makes it a popular choice for hedging, borders, and feature planting
