“What is a good flowering shrub for Zone 4? Question from Sandra Lee of Cottage Grove, Minnesota
Answer: There are so many great flowering shrubs that grow beautifully in USDA Hardiness Zone 4 winters! Here are three super hardy options to try:
1. Smooth Hydrangea (Hydrangea arborescens, USDA Hardiness Zones 3-9): There are lots of wonderful varieties of this summer-flowering beauty, and the shrubs grow well in partial shade and full sun. Two of the best to try are the giant-white-flowered Incrediball® and more compact, mauve-flowered Invincibelle Mini Mauvette®.
2. Potentilla (Potentilla fruticosa hybrids, USDA Hardiness Zones 2-7): These sun-loving, summer-flowering shrubs are long blooming and have flowers in yellow, white, or pink. They are also tolerant of drier, more well-drained soils. The golden-flowered ‘Happy Face‘ is a good performer.
3. Hardy Roses (Rosa hybrids): Loads of shrub roses really tough it out way up north. Those in the Oso Easy® group of roses are extra hardy and very high performing. There are lots to choose from with flowers of rose-red, peach, white, and pink. Try the super hardy (Zones 3-9), pink-flowered Oso Easy® Fragrant Spreader , which is fragrant, pretty, and spreads to form a low mass of roses from early summer to fall. The double red Oso Easy Double Red, is slightly less hardy, surviving in Zone 4a winters.
