Physocarpus 'Royal Jubilee'

‘Royal Jubilee’ Ninebark (Physocarpus opulifolius ‘Royal Jubilee’). The Physocarpus opulifolius ‘Royal Jubilee’, or ‘Royal Jubilee’ ninebark, is a deciduous ornamental shrub with a rounded, dense habit, appreciated for the remarkable evolution of its foliage throughout the seasons. In spring, its young leaves emerge in coppery and orange hues, then evolve into a luminous golden green in summer before returning to warm shades in autumn. Its spring bloom, composed of small pinkish-white flowers grouped in corymbs, attracts pollinators and adds a delicate touch to the colorful foliage.

To plant ‘Royal Jubilee’ ninebark, choose an appropriate exposure: sun to partial shade. The recommended soil is well-drained, ordinary soil. Water the root ball before planting 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 collar clear. Avoid systematic fertilizer applications without considering the richness of the soil. In Quebec, choose a period when the soil is thawed and easy to work.

Allow a width of 2 m (6 ft) to plan this plant’s space in the garden. The indicated height of 1.8 m (6 ft) helps choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Combine this variety with plants whose light and water needs are compatible. If you are considering a container, first check that its volume and drainage are suitable for root development. Roots in pots are more exposed to cold than those planted in the ground.
