A magnificent shrub, Hydrangea paniculata 'Phantom' has huge white flower heads, the largest we have discovered so far on this species. We have a spectacular group of five plants next to the entrance to the gardens here and this year they produced a superb display of flower heads, some up to 45 cm long.
The flower bracts are pale green in early summer, turning white from July to August, finally darkening to pink before falling in September. These bracts stand out well against the pretty green leaves.
To attain the largest possible flower heads, Hydrangea paniculata 'Phantom' should be pruned back hard to around 20 - 30 cm (1 ft) above ground level and mulched yearly.
