Hydrangea paniculata ‘Polestar’

Hydrangea paniculata ‘Polestar’ Description

Hydrangea paniculata ‘Polestar’ is a very compact deciduous shrub selected for early flowering and rapid colour change. Numerous panicles open pale green to white in early summer, then develop pink and increasingly rich reddish tones as the season advances. Its dense growth generally remains around 50 to 60cm high and similarly wide, making it one of the most container-friendly panicle hydrangeas. Grow in full sun or partial shade in fertile soil that remains moisture-retentive but drains freely. It is extremely hardy and flowers on current-season shoots, so winter cold rarely compromises the display. Regular watering is important in pots. Prune lightly in late winter or early spring to remove spent flowers and encourage a compact framework of strong new shoots.
