Grow Rosa 'True Serenity' for classic hybrid tea form with bold color and strong fragrance in your garden and in cut arrangements. You will get an upright, well-branched plant that typically reaches about 36-60 inches tall, with a mature spread of roughly 24-48 inches, making it easy to place in mixed beds or as a standout accent.
Give your rose full sun for best flowering and overall performance. Plant it in well-drained soil, and water deeply during establishment; once growing strongly, keep moisture consistent during bloom cycles, especially in heat. A layer of mulch helps even out soil moisture and temperature while keeping the root zone more stable.
Prune in early spring to remove dead or weak canes and to shape the plant for good airflow. Deadhead spent blooms to encourage more flowering, and feed with a balanced rose fertilizer during the growing season to support repeat bloom and healthy foliage.
In colder areas within its hardiness range, protect the base going into winter with extra mulch around the root zone. Space plants so air can move through the canopy, helping leaves dry faster after watering or rain and keeping the plant looking its best.
