Iceberg roses are everywhere in SoCal. Why? Because they are easy to grow and are almost always in constant bloom. Most roses repeat in 6 weeks from being pruned or deadheaded. Iceberg only goes 4 weeks from cut to flowering. Feed them once a month(Mar-Oct) and prune like other roses in January. I like Iceberg not only for the afore mentioned qualities but because it looks like a flowering shrub and not like a rose. Grow it amongst perennials and shrubs and they will compliment each other in your garden.
