Venerable Native Shrub, Hydrangea Arborescens, Warrants a Place in All Gardens - Cultivating the Enchanting Summer Marvel
Getting StartedGrowing smooth hydrangeas (Hydrangea arborescens) is a breeze! Native to Eastern and Central United States, this deciduous shrub thrives in a variety of environments and makes an excellent addition to any garden. Here's what you need to know.
What is a Smooth Hydrangea?Smooth hydrangeas make a statement with their heart-shaped green leaves, sturdy stems that turn yellow in fall, and show-stopping summer blooms. This common type of hydrangea is known for its lacecap and mophead flower forms, both offering delightful white or pink blossoms.
Climate & Hardiness ZonesEasy-peasy hydrangea care begins by picking the right location. These beauties grow best in part shade, but can tolerate more sun in cooler northern regions. They're a hardy bunch, withstanding USDA zones 3 through 9 [4][5].
Lighting & Sun ExposureIn the northern states, smooth hydrangeas require light that's a bit more intense than their southern counterparts [3]. Aim for a location with morning sun and afternoon shade to give your smooth hydrangea the ideal balance.
Soil RequirementsThese low-maintenance gems thrive in moist, well-draining soil rich in organic matter [2]. The plant isn't picky about the pH, making it adaptable to a wide range of environments.
WateringKeep the soil moist but not soggy, especially during hot weather. Overwatering should be avoided to prevent root rot [1][2].
Pruning and MaintenancePruning isn't a high priority for smooth hydrangeas, but a little maintenance goes a long way in keeping them looking their best. Prune in late winter once the worst of the cold has passed, and remove any sick or damaged canes [5].
Pest and Disease ResistanceSmooth hydrangeas are pretty resilient when it comes to pests and diseases. However, they may on occasion attract aphids, scale, or mites, which can be treated with Neem oil [3].
Wildlife BenefitsThe smooth hydrangea is a bee's best friend, with nectar and pollen attracting butterflies, moths, and pollinators to the garden [3]. The seeds are a tasty treat for birds, persisting into winter.
Varieties* 'Annabelle': With large, white flower clusters, the popular 'Annabelle' variety is a home run among gardeners.* 'Haas Halo': For larger, white flower heads in lacecap style, opt for 'Haas Halo', which prefers more sun than the wild form.* 'Incrediball Blush': Boasting large pink flower heads on a woody shrub, this variety provides a pop of color to any garden.* 'Invincibelle Ruby': If you're a lover of red and silvery pink, the 'Invincibelle Ruby' is the perfect addition to your garden.
Tips for Garden Success- Mulch the root zone during winter to protect your smooth hydrangea in exposed or colder locations [3].- Plant in the spring and enrich the soil with a few inches of organic compost [2].- Remember, smooth hydrangeas require consistent moisture, especially in the first year, and regular watering during dry periods [1][2].- Avoid fertilizing smooth hydrangeas unless your plant looks less than stellar or doesn't bloom, in which case a flower-boosting fertilizer applied early in the spring season can help [3].
