Hydrangea plant named 'True Blue'

Abstract

A new and distinct cultivar of Hydrangea macrophylla (Thunb.) named ‘True Blue’ originated as a controlled cross between the cultivars ‘Blue Sky’ and ‘Blue Danube’. The cultivar ‘True Blue’ has blue—R.H.S. 100 A (blue group) sepals at maturity and is distinguished from other similar cultivars of which the inventor is aware by its sepal color, and its compact and sturdy growth habit. ‘True Blue’ has large showy inflorescences, having both sepalous and non-sepalous florets, although at maturity the sepalous florets hide the non-sepalous florets.
