Ninebark

Common Ninebark (Physocarpus opulifolius). Physocarpus opulifolius, commonly known as common ninebark, is a deciduous ornamental shrub with a broad, rounded habit, prized for its hardiness and great adaptability. Very hardy, it is perfectly suited to northern gardens where it forms dense thickets or informal, structural hedges. In spring, it produces corymbs of small, pinkish-white flowers that attract pollinators, followed by decorative reddish fruits in late summer. Its vibrant green, finely lobed foliage creates an interesting texture throughout the season.

To plant common ninebark, choose a suitable exposure: sun to partial shade. The recommended soil is well-drained and tolerant of various soil types. 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 the soil's richness. In Quebec, choose a period when the ground is thawed and easy to work.

Allow a width of 2.5 m (8 ft) to plan this plant's space in the garden. The indicated height of 2.5 m (8 ft) helps choose its position relative to neighboring plants. Keep 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 directly in the ground.
