This magnificent rose is covered with numerous clusters of single 5 petaled, candy apple red blossoms from summer until frost. This plant is low maintenance and no deadheading is required for continuous blooms. It will create a bright spot in your garden.
Oso Happy Smoothie Rose can be used in perennial or shrub borders, as a specimen plant or in mass plantings. Since it’s thornless, it’s a great choice for containers on your deck, patio, swimming pool or adjacent to narrow walkways where you might accidentally brush up against it. It grows to be 3 feet tall and wide in a mounded form. It’s low maintenance, disease-resistant and drought and salt tolerant. Oso Happy Smoothie Rose was bred by David Zlesak of Minnesota.
Oso Happy Smoothie Rose Care
Add this rose to your landscape in a full sun location in USDA plant hardiness zones 4 to 9. Oso Happy Smoothie Rose will attract songbirds, bees and butterflies to your garden. When the buds begin to swell in the spring, prune it back by a third or more.
Oso Happy Smoothie Rose Spacing
Space plants a minimum of 36 inches apart on center to provide sufficient airflow. In garden planters, choose a container at least 24 inches wide.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
- When to Prune
- Late winter to early spring, before new growth starts
