Abstract
A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘Carina’ originated as a found plant in a cultivated area of ‘Orion’. The cultivar ‘Carina’ has a R.H.S. 68 A (red-purple group) bi-color pigmentation pattern on its sepals at maturity, with the pigmentation giving way to non-pigmented margins and is distinguished from other similar cultivars of which the inventor is aware by its stable sepal color pattern, its sturdy growth habit, and small leaves. ‘Carina’ has large showy inflorescences, having both sepalous and non-sepalous florets, with the sepalous florets hiding the non-sepalous florets.
