Grow Grandiflora Rose 'Mother of Pearl™' (Rosa 'Mother of Pearl™') for luminous, shell-pink, fully double blooms that repeat through the season and look beautiful in beds and borders. This grandiflora rose forms an upright, bushy plant about 36-48 inches tall with a spread around 24-36 inches, making it easy to fit into mixed plantings or as a featured specimen.
Give your rose full sun for best flowering and overall vigor. Plant in fertile, well-drained soil enriched with compost, and water deeply to keep the root zone evenly moist, especially during establishment and hot, dry periods. A 2-3 inch mulch layer helps conserve moisture and keeps soil temperatures more stable; keep mulch a few inches back from the canes.
Feed in spring as new growth begins and again after the first heavy flush of flowers, following your preferred rose fertilizer schedule. Deadhead spent blooms to encourage repeat flowering, and remove any weak, crossing, or damaged stems to improve air flow. Maintain a consistent watering routine at the base of the plant rather than overhead to help keep foliage cleaner.
In USDA Zones 5-9, protect the crown in colder areas with additional mulch after the ground begins to freeze, and prune more heavily in late winter to early spring as buds begin to swell. Space plants so mature growth has room to expand and you can easily reach in for pruning and seasonal cleanup.
