Hardiness Zone (3-9):
This resilient shrub thrives in hardiness zones 3 to 9, showcasing adaptability across various climates and making it suitable for a wide range of gardens.
Smooth Hydrangeas prefer well-draining soil rich in organic matter. A blend of loamy soil with consistent moisture content ensures optimal growth and flowering.

These hydrangeas bloom during the summer, showcasing large, round clusters of flowers in shades of white, pink, or green. Flowering typically begins in late spring or early summer and lasts through the season.
Smooth Hydrangeas exhibit a rounded, mounding growth habit, providing a compact and neat appearance in garden beds or borders.
One notable feature of Smooth Hydrangeas is their ability to retain dried flowers on the plant, extending visual interest and appeal through the fall and winter months. These dried flowers add texture and charm to winter landscapes.
