Annabelle Smooth Hydrangea

Plant family: Hydrangea arborescens ‘Annabelle’

Location: Art Trail, North Lawn Trail

Growing zone: 3-9

Height: 3-5 ft.

Spread: 3-6 ft.

Bloom time: May, June, July

Bloom description: Clusters of white flowers decorate large, symmetrical, rounded heads or corymbs, which typically see a circumference of 8-10 in. The heads can be heavy, and after a rain, can droop to the ground. They bloom on new wood, so prune in late winter; however, if left unpruned, they bloom just fine.

Leaf type: The 3-6 in., serrated leaves are elliptical. The dark-green summer color fades to soft yellow in autumn.

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 it has a rounded habit and can fit in compact places. They prefer part shade with morning sun, and will wilt quickly in afternoon sun. Annabelle likes average, well-drained soil, but can tolerate poorer soils.

Wildlife benefits: Used as a source of nectar for some pollinating species. Turkeys browse the seeds in the fall. Host plant to the hydrangea sphinx moth.
