Do Iceberg Roses Like Full Sun?

Floribunda "Iceberg"

• The floribunda shrub "Iceberg" will grow to 4 feet and will create a 3-foot mound. The semidouble white blooms are up to 4 inches across and are born on inermis, or nearly thornless, stems. The blooms don't have a strong rose scent, but the foliage emits the scent of honey. It is a repeat flowering rose with a floriferous spring flush. It is mildew-resistant and is mildly resistant to black spot. It is hardy in U.S. Department of Agriculture plant hardiness zones 4 through 9.

Climbing "Iceberg"

• "Climbing Iceberg" is a sport of the floribunda shrub, also hardy in USDA plant hardiness zones 4 through 9. The white double blooms sometimes revert to pale pink later in the growing season. This rose is known as a medium climber, growing to 14 feet. It is a vigorous climber offering excellent repeat blooms throughout the growing season. It has been known not to climb or send out long shoots, a result caused by improper propagation.

Growing in Partial Shade

• Roses grown in partial shade need a little extra care. If growing either the floribunda shrub or the climbing sport of "Iceberg" in partial or dappled shade, good drainage is essential, particularly during the winter months. The roses will need to be pruned to an open shape to ensure good air circulation and no buildup of excess moisture, which promotes disease. They are strong and vigorous roses when grown in sunny locations, with good disease and mildew resistance, but when they are grown in partial shade, they will need to be fertilized more often than other roses. If your garden has more partial shade than sunlight, choose single-petaled roses. In general, rose blooms with few petals are more shade-tolerant.

Design Uses

• "Iceberg" shrubs form a stunning display when grown as a hedge. They could line a driveway, enclose a boundary or separate the rose garden from the vegetable garden. The shrub could also be planted at the back of a mixed border, given enough space. Although the climber grows to 14 feet, it is not overly rampant. It grows best on a wall or trellis. Consider growing it along a white picket fence, against a garden shed or porch posts. Locations in full shade should be avoided.
