Common Name: Annabelle Smooth Hydrangea
Botanical Name: Hydrangea arborescens ‘Annabelle’
Family: Hydrangeaceae
Zone: 3-9
Height: 3-5′
Spread: 3-6′
Bloom Time: June, July, August
Bloom Description: Clusters of white flowers decorate large, symmetrical, rounded heads or corymbs, which typically see a circumference of 8-10”. The heads can be heavy and after a rain, they tend to droop and sometimes touch the ground. They bloom on new wood, so prune in late winter; however, if left unpruned, they bloom just fine.
Trail/Garden Location: Another widely used shrub species on our site, Annabelle Hydrangea is seen planted along the Art Trail, East Terrace and North Lawn.
Garden Uses: This small shrub is used in our garden in shrub-borders as well as in mass plantings. The effect of the large, colorful blooms in a mass planting is stunning! This shrub is perfect in a home garden, as they have a rounded habit and can fit in compact places. They prefer part shade with morning sun. If they are in afternoon sun, they tend to wilt quickly. Annabelle likes average, well-drained soil, but can tolerate poorer soils.
Wildlife Benefits: Used as a source of nectar for some pollinating species. Turkey’s browse the seeds in the fall. Host plant to the Hydrangea Sphinx moth.
Leaf Type: The 3-6″, serrated leaves are elliptical. The dark green summer color fades to soft yellow in autumn.
