Moondance™ floribunda rose (Rosa 'Jactanic') produces masses of creamy, white flowers at the tips of branches clothed in glossy green leaves on an upright spreading shrub, which grows to 4 feet by 3 feet in size. The nicely scented flowers are much beloved by honeybees and butterflies. All roses prefer full sun and moisture-retentive, loamy soils. Roses respond favorably to moderate fertilization from early June through midsummer, but avoid mulching soft growth subject to freeze damage. No fertilization after mid-August should be applied. Black spot and powdery mildew are two of the more frequent diseases of this cultivar. Both diseases become problematic as temperatures and relative humidities rise in late summer. Planting the roses in areas with good air movement helps—but can’t prevent—these diseases, and in a bad year, pesticides will need to be applied to prevent the plants from defoliating. Aphids and Japanese beetles are the two most frequent insect pests. Aphids can be reduced in numbers by spraying the infected sites with a strong spray of water (aphids catch cold). Control of Japanese beetles is more problematic, however, and they have to be hand-picked from the plant. Adult Japanese beetles are virtually impervious to many insecticide sprays. Effective treatments involve the applications of spores to turf areas that feed upon the developing larvae.

This cultivar is a sport (bud mutation) that produces more flowers than the parent plant, Rosa ‘Iceberg’. Typically, sports like this are part of the natural genetic variation and are not induced through bio-engineering.
