- Hydrangea Type: Arborescens
- Hardiness Zone: 3-8
- Bloom Time: Late-Spring to Mid-Summer
This hydrangea stem adorns impressively giant, white or pink, ball-shaped flowers that bloom from the spring to the middle of the summer. The stem of this species is upright and strong so it won't result in drooping from the weight of the blooms.
It grows high to around four to five feet (1.2-1.4 m) high and wide, so it would make a fantastic addition to your garden. This species only blooms following a spring growth so it won't bloom and wither during winter.
