Icecap Rose

Rosa 'Icecap'

The Story

Plant Bio

Roses are woody perennial flowering plants of the genus Rosa, prized for their often fragrant flowers which come in a vast range of colors, forms, and sizes.

Icecap is a floribunda rose renowned for its extraordinary disease resistance and prolific production of pure white flower clusters. It maintains a compact, rounded shape and is self-cleaning, requiring no deadheading.

Uses & Benefits:

Icecap provides a massive and continuous display of pure white flowers, creating a clean, elegant, and high-impact visual. Its compact, tidy habit makes it suitable for both formal and informal garden designs.

Its outstanding disease resistance and self-cleaning nature make it one of the lowest-maintenance roses available, perfect for homeowners and commercial landscapers seeking beauty without the work.

The clusters of flowers provide an abundant source of pollen for bees and other beneficial insects over a very long season.

How to Grow

Plant in a location that receives at least six hours of sun daily.
Dig a hole twice the width of the pot.
Amend the soil with compost for better structure and fertility.
Set the plant in the hole so the crown is level with the ground.
Backfill the hole with the amended soil and water in well.
Apply a layer of mulch around the base, avoiding the canes.

Pro Tip

This rose is exceptionally self-cleaning; resist the urge to deadhead and let it drop its own petals to save time.
