Hydrangea macrophylla ‘Hot Red Purple’ Description

Hydrangea macrophylla ‘Hot Red Purple’ forms a compact rounded deciduous shrub with broad green foliage and dense flower heads in saturated red-purple shades. Blooms may appear more crimson or magenta in neutral soil and develop deeper violet tones where conditions are acidic. Plants generally reach around 80cm to 1.2 metres high and wide. Grow in partial shade or gentle morning sun in fertile, humus-rich soil that remains consistently moist but drains freely. It is well suited to large containers and sheltered Irish borders. Avoid strong midday sun, which can scorch both foliage and flowers. Prune lightly in spring, removing dead stems and faded flower heads while preserving healthy previous-season growth carrying the developing buds.
