Hydrangea paniculata Little Lime, 10LHalf the size of its sibling Limelight, the compact Hydrangea paniculata Little Lime is ideal for planting in a smaller garden or in a large container (if kept well watered). The flowers are conical and lime green in colour, fading to white and tinted with pink as the season progresses. They can be used to great effect in floral arrangements, fresh or dried.
