Iceberg
Iceberg is a famous white floribunda with several synonyms and a separate climbing sport. Keep bush Iceberg distinct from Climbing Iceberg when giving pruning or size advice.
Growing notes
In humid regions, monitor black spot and rust despite its reputation. In UK and mild climates, RHS H6 and AGM notes are relevant. In containers, check whether the plant is bush or climbing form.
What to photograph
- Whole plant from several feet away, including support or container.
- A fresh bloom and an older bloom.
- Leaf upper and lower surfaces.
- Cane base, graft or own-root shoots if visible.
- Any disease, mite, herbicide, or RRD-like symptoms with dates and weather context.
Common cautions
- Do not merge Climbing Iceberg into this page without a clear note.
- White blooms show weather spotting more visibly than dark blooms.
- Match advice to region, root system, and rose class before pruning or treating.
- Use Regional Rose Care Tips and local extension or RHS guidance for climate-specific adjustments.
