Japanese Spirea 'Crispa' (Spiraea japonica 'Crispa')

‘Crispa’ Japanese Spirea (Spiraea japonica ‘Crispa’). Spiraea japonica ‘Crispa’ is a distinctive summer spirea prized for its finely toothed and slightly wavy foliage, which gives it a unique texture in the garden. This deciduous shrub develops a rounded, dense habit, wider than it is tall, ideal for borders, mass plantings, and foundation plantings. In summer, its corymbs of deep pink flowers generously cover the dark green foliage, creating an attractive contrast and attracting pollinators. Its crinkled foliage sometimes takes on reddish hues in autumn, adding extra seasonal interest.

To plant 'Crispa' Japanese spirea, choose a suitable exposure: sun. The recommended soil is neutral to slightly acidic, well-drained. Water the root ball before planting it in the ground and ensure that water can drain after planting. During establishment, check the moisture by hand before watering again. Spread mulch around the base, leaving the crown clear. Avoid systematic fertilizer applications without considering soil richness. In Quebec, choose a period when the ground is thawed and easy to work.
