✂️ Care
Very easy to grow. Prune lightly after flowering to maintain a compact shape and encourage dense branching.
Apply an organic mulch around the base to retain soil moisture and regulate temperature. A balanced fertilizer in spring supports abundant and prolonged flowering.
No staking is necessary thanks to its naturally robust structure and stable bushy habit.
This hardy shrub offers a remarkable visual presence in hedges, beds, or as a specimen plant, with its bicolor white and pink flowers that brighten the garden from June to August.
