Add romantic color to your landscape with Rosa 'True Sincerity' (Rose 'True Sincerity'), a compact floribunda that produces clusters of fully double blooms in creamy yellow edged with rich pink-red. You will enjoy repeat flowering through the growing season along with a pleasing rose fragrance on a neat, bushy plant that fits easily into beds, borders, and containers.
Plant your rose where it receives at least 6 hours of sun for best performance; it will tolerate very light afternoon shade, but fewer hours of sun can reduce bloom size and petal count. Provide fertile, well-drained soil that stays evenly moist but never waterlogged. A 2-3 inch layer of mulch helps keep roots cool and reduces soil splash on foliage; keep mulch a few inches away from the canes.
At maturity, expect about 24-48 inches tall and roughly 24-48 inches wide. Water deeply to encourage strong roots, especially during the first year and during hot, dry stretches. Feed with a balanced rose fertilizer in spring and again after bloom flushes, and deadhead spent flowers to encourage more blooms.
Prune in early spring as buds begin to swell, removing dead or crossing canes and lightly shaping the plant to improve airflow. With good light, consistent care, and timely pruning, this rose rewards you with continuous color and a tidy, landscape-friendly habit.
