Culture
Best grown in medium moisture, slightly acidic, well-drained garden loams in full sun to very light 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.
CLIMBING CAREFREE SUNSHINE may also be cut back to 12-18” above the ground in spring.
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.
Climbing roses usually need support by securing to a pillar, fence or wall but some can be grown more as a shrub. Some are also suitable as a groundcover. Many rebloom throughout summer but some flower just once in spring.
Genus name comes from the Latin name for rose.
CLIMBING CAREFREE SUNSHINE is an ever-blooming, low-maintenance climbing rose that typically grows to 8-10’ tall. It was discovered as a spontaneous naturally-occurring mutation of Rosa ‘Radsun’ CAREFREE SUNSHINE. U. S. patent documents assert that this rose is noted for its (a) upright climbing growth habit, (b) profuse bloom of semi-double yellow flowers (3-4” diameter), (c) satiny medium green foliage and (d) excellent resistance to black spot. Flowers (3-4’ diameter) commonly appear in clusters of 4 per floral stem over a long May to frost bloom period. Flowers have a slightly spicy fragrance. Glossy, dark green compound leaves typically have 3-7 oval serrated leaflets. Flowers give way to orange hips in fall. U. S. Plant Patent PP16,611 was issued on June 6, 2006.
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 summer 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.
Uses
Best as a climber rose for walls, arbors, trellises, along fences or around pillars.
