Culture
Best grown in medium moisture, slightly acidic, well-drained garden loams in full sun to part shade. Best flowering and disease resistance generally occur in full sun, however. Water deeply and regularly (mornings are best). Avoid overhead watering. Good air circulation promotes vigorous and healthy growth and helps control foliar diseases. Summer mulch helps retain moisture, keeps roots cool and discourages weeds. Remove spent flowers to encourage rebloom. Crowns need winter protection in cold winter areas such as St. Louis. Remove and destroy diseased leaves from plants, as practicable, and clean up and destroy dead leaves from the ground around the plants both during the growing season and as part of a thorough cleanup during winter (dormant season). Prune as needed in late winter to early spring.
Plants can be pruned back to 12-18” if desired to limit height.
Noteworthy Characteristics
Rosa is a genus of about 150 species of deciduous (occasionally evergreen) shrubs and climbers noted for their beautiful, often fragrant, single, semidouble or double flowers which are borne singly or in clusters on often prickly stems clad with 5-9 leaflets often having toothed margins.
Shrub roses are usually large-growing bushes between 4-10 feet tall and as wide. They are a very diverse group of hybrids and usually produce clusters of flowers several times a year but some may bloom just once in spring. They do not require the heavy pruning required of hybrid tea, floribunda and grandiflora roses unless being pruned to control size. Plants can be allowed to grow large with minimal pruning.
Genus name comes from the Latin name for rose.
CAREFREE SUNSHINE is a compact, mounding, ever-blooming, low-maintenance shrub rose that typically grows to 3-4’ tall and as wide and noted for its semi-double yellow flowers, glossy medium green foliage and excellent resistance to black spot. This rose is a cross between unnamed male and female parents. Semi-double bright yellow flowers (3-4” diameter) bloom over a long May to frost bloom period. Flowers commonly appear in clusters of 4 per floral stem. Flowers have a slightly spicy fragrance. Glossy, dark green compound leaves typically have 3-7 oval serrated leaflets. U.S. Plant Patent PP13,063 was issued on October 8, 2002.
Problems
Roses are susceptible to a large number of diseases, the most common of which are black spot, powdery mildew, rust and rose rosette. Although good cultural practices are the first line of defense in disease control, regular preventative fungicide applications throughout the growing season are usually required, particularly in humid climates with regular rainfall such as the St. Louis area. Potential insect problems include aphids, beetles, borers, scale, thrips, rose midges, leafhoppers and spider mites. Local rose associations and extension services are usually able to offer specific recommendations and advice for selecting and growing roses.
CAREFREE SUNSHINE is particularly noted for having excellent resistance to black spot.
Uses
Grow as a specimen or in small groups in borders, cottage gardens, foundations or rose gardens. Also effective as a hedge.
