What is the difference between a white iceburg and a white icecap roses?
These are very similar roses developed by different breeders. Iceberg is hardy in zones 4-9 while icecap is listed for zones 5-9. Iceberg is approx 4 ft tall, taller than icecap which is listed as 2 1/2 ft tall. Both have 25 petals per bloom and both are considered floribunda shrub roses. I hope this helps.
