Botanical name*Rosa rugosa*

Rugosa rose ‘Alba’ (Rosa rugosa ‘Alba’). The rugosa rose ‘Rosa Rugosa Alba’ is the white-flowered version of the rugosa species, with the same qualities of hardiness and abundant flowering. Its pure white single flowers are fragrant and are followed by red fruits. Very hardy, it reaches 120 to 180 cm, with dark green crinkled foliage. An excellent choice for informal hedges and natural gardens in harsh climates. The indicated adult size is 160 cm (5 feet) in height and 150 cm (5 feet) in width.

To plant rugosa rose ‘Alba’, choose a suitable exposure: full sun or at least 6 hours of direct sun per day. The recommended soil is: rich, well-drained soil. 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.

Allow a width of 150 cm (5 feet) to organize the plant's space in the garden. The indicated height of 160 cm (5 feet) helps to choose its position relative to neighboring plants. Maintain access to the base for weeding, checking moisture, and removing damaged parts. Associate 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. Potted roots are more exposed to cold than those planted in the ground.
