Quick Overview:

Hydrangea macrophylla ‘Enziandom’ is part of the hortensia or mophead group (large sterile florets arranged in globular or "mophead"-like panicles). It is a compact, deciduous shrub with a rounded habit which typically grows to 3-4′ tall. Features clusters of deep blue sterile florets in large, globular heads (corymbs) which bloom in July for up to two months. By reputation, this is one of the best of the deep blue hydrangeas. However, flower color becomes pinkish when soil pH rises above 6.5 and deep pink in fully alkaline soils. Dark green foliage turns attractive shades of copper to dark red in autumn.

Best grown in rich, medium moisture, well-drained soils in part shade. Tolerates full sun only if grown in consistently moist soils. Soil pH affects the flower color (blue in highly acidic soils and lilac to pink in slightly acidic to alkaline soils). Add aluminum sulfate to the soil to make the flowers bluer or add lime to the soil to make the flowers pinker. Begin soil treatments well in advance of flowering, as in late autumn or early spring. Plants generally need little pruning. If needed, prune immediately after flowering by cutting back flowering stems to a pair of healthy buds. Prune out weak or winter-damaged stems in late winter/early spring. Best to mulch plants year-round with 3" of shredded bark, peat or compost. Winter hardy to USDA Zone 6.
