Hydrangea paniculata 'Limelight' is a deciduous shrub prized for its large, showy flower panicles and strong growth habit. It typically grows to a height of 1.5m width with a similar spread, forming an upright, bushy shape. The plant produces dense, cone-shaped clusters of flowers that emerge lime-green in summer, gradually transitioning to creamy white, soft pink, and deep rose as the season progresses. It is widely used in mixed borders, hedging, and specimen planting due to its long flowering period, striking colour changes, and suitability for cut or dried flower arrangements.
