Description and Growing Information

General DescriptionAn upright hybrid tea rose with rich, deep green glossy leaves and delicately-scented, fully double blooms with buttery-yellow petals. The flowers become a darker yellow-orange in the centre of the bloom, while nearly blooming flowers are a richer orange in colour.
ID CharacteristicCommonly thorny stems, pinnate leaves and singular or clustered 5-petalled flowers, followed by attractive vermillion red to purplish-red fruits.
LandscapeThe Sunny Sky Rose is best used in flower borders and beds. It is gaining popularity as cut flowers due to its pleasing buttery-golden hues. Increasingly the rose is found adorning city & courtyard gardens in urban areas. This species can also be used in informal gardens and to decorate cottages.
PropagationPropagate with semi-ripe cuttings in the later summer months or with hardwood cuttings in the fall, or by chip budding any time during the summer.
CultivationGrows best in humus-rich, moist but well-drained soil. Make sure to place Sunny Sky Roses in a sun-rich and open position. Mulch in the late winter. Apply a balanced fertilizer in late winter or early spring, and again in the early summer months to improve flowering.
PestsThe most common rose pests are aphids, notably the rose aphid. Rose leafhopper, glasshouse red spider mite, scale insects, caterpillars, large rose sawfly, rose leaf-rolling sawfly and leaf-cutter bees can also damage the rose. Deer and rabbits can also cause damage due to grazing. In terms of diseases, rose black spot, rose rust and rose powdery mildew are the most common, but can also be affected by rose dieback, replant disease, a canker or honey fungus.
