Creambush

Also known as: Ironwood

Holodiscus discolor, commonly known as creambush, is known for its cascading bunches of fragrant white flowers. A hardy generalist, this species serves as a lovely ornamental for gardens, doing well even in poor soil or shaded areas. And creambush isn't just nice to look at - it has practical uses as well. The species is sometimes called "Ironwood" because its sturdy, straight wood was historically used to make arrow shafts, wooden nails, tools, and more.

Attributes of Creambush

Growth Rate

Creambush's moderate growth rate is evident from spring through fall, with a marked increase in foliage and height. Its characteristics, such as leaf production and floral bloom, adapt optimally to sustain this pace. Oddly, its growth slightly decelerates in late summer, before resuming in fall.

Distribution of Creambush

Distribution Map

Creambush originates from the temperate regions of North America and has found its way into cultivation far beyond its native range. In its indigenous lands, it thrives mainly in the western coastal areas and inlands. As an introduced species, creambush has adapted to similar climates in other major regions of the Northern Hemisphere. The plant is also recognized for its ability to acclimate to cultivated settings, becoming a fixture in diverse landscapes away from its original habitat.

Garden Soil

Soil Type

Water: Originating from North American woodlands and shrublands, creambush prefers moderate moisture. It requires weekly watering and can endure brief dry spells. Mulching is recommended to retain soil moisture, especially during the active growing season for optimal health and vigor.

Fertilize: Fertilize creambush with balanced fertilizer in early spring and a high nitrogen blend quarterly during active growth. Reduce feeding in fall and none in winter. Mix fertilizer with water and soak the soil, watering afterward to prevent root burn. Watch for over-fertilization signs like yellowing leaves.

Pruning: Creambush produces cascading clusters of creamy white flowers. Prune in late spring after flowering to remove dead branches and thin crowded areas, promoting healthy growth and airflow. Avoid heavy pruning to prevent stress. Regularly removing old wood rejuvenates creambush, enhancing its blooms and appearance.

Propagation: Creambush propagates effectively in autumn and winter via cutting and layering. The process demands moderate effort, yielding new growth success. Maintain clean cuts and optimal soil moisture to enhance propagation success rates.

Repotting: Repot creambush every 2-3 years in spring using a container 2 inches larger than its root ball. Provide well-draining soil and regular watering post-repotting to support recovery and encourage healthy growth and blossoms.
