Rugosa rose ‘Alexander Mackenzie’

‘Alexander Mackenzie’ Shrub Rose (Rosa ‘Alexander Mackenzie’). The ‘Alexander Mackenzie’ Shrub Rose is a vigorous Canadian variety known for its large, deep red flowers and exceptional resistance to cold climates. This rose, with its upright and slightly arching habit, produces classic double flowers that appear abundantly from summer until the first frosts. Its dense, dark green foliage highlights the intensity of the flowers and provides excellent ornamental presence in beds, hedges, and landscape gardens. Developed as part of the Canadian Explorer program, Rosa ‘Alexander Mackenzie’ combines hardiness, prolonged flowering, and ease of maintenance.

To plant the ‘Alexander Mackenzie’ shrub rose, choose a suitable exposure: full sun. The recommended soil is rich and well-drained. Water at the base and allow air to circulate between the branches. Remove dead parts with a clean tool, then adapt pruning to the rose group. Winter protection depends on its hardiness and the possible presence of a graft union. Water the root ball before planting and ensure that water can drain after planting. During establishment, check the soil moisture by hand before watering again.

Allow a width of 1.5 m (4.9 ft) to plan for this plant in the garden. The indicated height of 2 m (6.6 ft) helps in choosing its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Pair 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.
