Hydrangea macrophylla ‘Bailmacseven’ Eclipse® brings colour before its first flower ever opens. New and mature leaves retain a deep purple-black tone, forming a dramatic ground for red-to-pink mopheads with lighter centres. The contrast is rich, contemporary and exceptionally rare at this scale of hydrangea foliage, allowing the plant to function as a genuine design object throughout the growing season.
Dark foliage adds depth to a partly shaded border and brings out paler neighbouring plants. Pair it with white flowers or fine green foliage so the broad flowerheads have room to stand out. Near a seating area, the change from creamy centres to coloured sepal edges becomes especially noticeable.
Dark foliage provides a lasting backdrop for large bicoloured flowerheads.
Deep purple leaves retain their character through the growing season, including the intervals between blooms.
Large flowerheads combine pale centres with pink to purple shades, depending on soil conditions.
The full crown forms a compact block of colour that can anchor a partly shaded planting.
Why you will love it: Near-black foliage keeps the composition dramatic before, between and after its red-pink flowers.
Use on an east or north-east aspect as a dark focal point in the middle layer or alone in a large pot; allow at least 1.2 m so the near-black foliage reads as a coherent mass.
Hakonechloa macra ‘Aureola’, Brunnera macrophylla ‘Jack Frost’ and Anemone ‘Honorine Jobert’ share cool partial shade; gold, silver and clean white define the near-black foliage without competing with it.
Morning sun with afternoon shade; intense midday radiation can scorch leaves and sepals.
Maintain even moisture without permanent saturation. Water deeply when the top 2–3 cm begin to dry.
Winter hardy, though late frost can injure already formed flower buds.
All parts are considered inedible and may cause illness if chewed.
Morning sun with afternoon shade; intense midday radiation can scorch leaves and sepals.
Maintain even moisture without permanent saturation. Water deeply when the top 2–3 cm begin to dry.
Humus-rich, cool, freely drained soil; pH influences some anthocyanin colours, but not every red cultivar equally.
Use hydrangea feed sparingly in spring and, if required, once more in early summer.
Deadhead to a strong pair of buds and remove only dead or genuinely old stems.
Do not hard-prune in autumn; old heads provide a little protection to the upper buds.
During the first months, roots establish while older stems retain valuable pre-formed flower buds. Even moisture and gradual light acclimatisation take priority over formative pruning.
The crown gains volume without losing its dark colour, while flower buds distribute across older and newer wood.
At full maturity the crown reaches about 0.9–1.5 m in height and 0.9–1.5 m in spread. Final planting distance must follow that scale rather than the plant’s current young volume.
A rounded shrub with large opposite purple leaves and broad flowerheads.
After leaf fall, the woody branches and their buds remain visible.
New leafy growth carries the characteristic flowerheads.
The seasonal views show natural changes in growth and flowering.
Eclipse® originated in Bailey’s breeding programme in Georgia, USA. David Roberts, Oren McBee and Justin Schulze sought Hydrangea macrophylla with dark foliage that retained its colour throughout the season. In summer 2016 they crossed seed parent HM16-P4-01 with pollen parent HM16-R13-02.
In summer 2018 they selected a seedling with deep purple foliage and rounded mophead flowerheads. Softwood-cutting propagation began that season at Winterville. The cultivar was recorded as ‘Bailmacseven’ in US plant patent PP34544 and joined the First Editions® collection under the commercial name Eclipse®.
The large coloured structures in a mophead are enlarged sepals of sterile flowers. In Eclipse®, under non-bluing conditions, they have pink-red margins and creamy centres. This pattern repeats across many small flowers in a single head.
Broad, toothed leaves grow in opposite pairs along the stem. This arrangement, together with short lateral shoots, helps reveal the branching structure beneath the full crown.
Six exact answers about placement, watering, pruning and seasonal behaviour for Eclipse®.
Yes. Deep purple foliage is a defining feature throughout the growing season. Its intensity is influenced by light and growing conditions.
In Hydrangea macrophylla, flower colour responds to soil pH and aluminium availability. Bloom colour can change while the dark foliage remains a separate characteristic.
No. Retain healthy branches and their buds. If adjustment is necessary, prune lightly after the first flowering and remove dead wood once it is clearly identifiable.
Eclipse® can flower on older and new growth. Keeping existing buds supports the first display; there is no need to remove them to encourage new ones.
Choose morning sun and afternoon shade, with fertile, well-drained soil that does not dry suddenly. Hot afternoon exposure is especially demanding for a potted plant.
No. This is a deciduous hydrangea. Bare stems with their buds remain alive and produce new growth in spring.
