Everything about this plant feels effortless, and a lot of it actually is! Oso Easy Ice Bay rose has the most elegant, milky white blooms centered with vibrant mustard stamens. Creamy colored flower buds open to white and stay that color until they are spent, unlike some white roses that can age to pink. They flourished out in our garden and field trials, showing us just how disease resistant they are and how little care they need in the summer. They’ll even rebloom abundantly without deadheading! It’s the perfect fit for cut flowers, white gardens or moon gardens, and tucked within a border. It can lean toward a cottage or formal style, depending on which plants you pair with it.

Why grow Oso Easy Ice Bay rose?
– Extremely long flowering window.
– Elegant blooms with prominent stamens make a great addition to a cut flower arrangement.
– Easy to care for with its great disease resistance and nonstop blooming (without deadheading!).


Light: Thrives in full sun. When planted in an area that gets less than six hours of direct sun each day, it will not flower as prolifically.

Soil: Prefers moist soil that drains easily. Any period of extended sogginess will not be tolerated. In terms of pH, it prefers either neutral or acidic soils over basic soils.

Water: Average water needs. Be sure to water from below when possible.

Fertilizing: Apply a granular rose fertilizer in late winter/early spring when the soil is workable and again in late spring to give the plant a boost for rebloom.

Pruning: Pruning is recommended in early spring. Remove weak branches in the middle and about 1/3 of the height and width. Make cuts just about 1/4 of an inch above a bud. Dead or damaged wood can be removed at any time, just cut back to a set of leaves.

Other: It can be used as a cut flower! For its longest vase life, cut vertically up the stem about 2 inches. This will help it absorb more water.
