The Iceberg Rose is the most popular white flower rose shrub planted throughout California. Although it is not fragrant, it is desired because they produce very abundant amounts of beautiful large white flower blossoms that sometimes have a pink tint.
Iceberg roses are medium sized, rounded shrubs with dark green leaves and thorns. They are vigorous and very resistant to disease.
It is also considered as a semi deciduous shrub that becomes partially dormant in the Winter, but flowers multiples times per year. Spring time brings the first blossoms of the year that carries into the Summer. This is followed by a second flush of flower blossoms in the late Summer that hold until the Fall.

General Plant Information
Iceberg Rose Shrub | White Rose Plant Information and Care
Plant the Iceberg Rose in the full sun or even partial shade, as Icebergs are one of the few roses that will thrive and produce flower blossoms under both light exposure. In a planting area, Iceberg Roses are planted as a mid size shrub. They can be placed behind a foreground plant like boxwoods, begonias, or annuals. A large shrub can be planted behind them as a background such as Ligustrum.
Irrigation and Fertilization
Water regularly, about 1 – 3 times a week with automatic sprinkler system for best results. Irrigate deeply and adjust the frequency depending on the weather. Fertilize with a balanced fertilizer such as one with a 1-1-1 NPK ratio in the Spring through Summer. Do not fertilize in the Fall.
Pest Management of Iceberg Roses
Although a very vigorous and resistant species, the use of an all-in-one rose feed, insecticide, fungicide, and miticide products help protect against common pests and diseases.
Powdery mildew is a fungus that commonly affects the Iceberg Rose during the late Winter and early Spring. Proper irrigation management, prune to reduce density and allow for more air flow if needed, and apply organic fungicides such as Bordeaux, Liqui-cop, and Neem oil.
Additional InformationPlant Type: Deciduous
USDA Hardiness Zones: 4-9
Soil and Planting: Plant in soil that drains well. Dig a hole that is as deep as the tree’s roots and at least twice as wide.
Place the tree in the hole and backfill around the plant’s roots with a mixture of the native soil and high-quality planting mix that has washed sand and organic fertilizer.
Create a basin around the roots drip zone so that water collects. Water deeply until the roots and nearby soil is saturated and reaches field capacity.

The two factors that determine if a deciduous fruit trees will grow well and produce fruit in a certain area are the Chill Hour Requirement and the Cold Hardiness. “Chill hours” are the amount of cold a deciduous fruit tree need to produce fruit. This is measured in the number of hours below 45 degrees Fahrenheit a plant must experience during its winter dormancy. Paradise Nursery only grows Low Chill fruit trees that meet the chill requirements of all areas of the United States.
The second factor is Cold Hardiness. Cold Hardiness refers to the minimum temperature a plant can tolerate. The USDA’s Cold Hardiness Zones indicate the average minimum winter temperatures of areas. Based on the shipping zipcode, our website will only allow you to add plants to your cart that grow within your USDA Hardiness Zone, and tolerate your climate.
Pollination & Propagation
(Grafting/Cutting) Most of Paradise Nursery’s edible plants are self-fruitful. Self-pollinating trees do not require an additional tree to produce fruit. For your convenience, we have indicated which trees require a pollinator, and their associated pollinators. Only the sweet cherries, avocados, and some plums require a pollinator. All of our other propagated edible plants do not require a pollinator. All of our edible plants are either grown from cuttings, budded, or grafted. This way, we can ensure that our plants are high quality and fruit immediately. Plants will generally begin fruiting within a year of planting.
