Smooth Hydrangea
The cultivar 'Annabelle' produces flower heads up to 30 cm in diameter.

Smooth Hydrangea is one of the most beloved ornamental plants in gardening, native to the eastern part of North America. It is an undemanding plant that has captured the hearts of gardeners worldwide thanks to its reliability and prolonged flowering. Unlike the panicle hydrangea, smooth hydrangea is less demanding in terms of growing conditions and more hardy in cold regions — which is precisely why it is so popular in Ukraine.
The shrub is distinguished by enormous flower clusters that appear in summer and persist until autumn. Freshly opened flowers are milk-white, gradually acquiring creamy and sometimes pink tones — this is a natural aging process of the petals. The cultivar 'Annabelle' is a true star among selected forms, with enormous spherical flower heads that can reach 30 cm in diameter. There are also cultivars with flowers that change colour from white to pink throughout the season, such as 'Incrediball'.
In the garden, smooth hydrangea works wonderfully both in combinations with other plants and as a specimen plant. It looks organic alongside astilbe, hosta, and fern — these compatible companions love the same conditions: partial shade and moisture. You can plant smooth hydrangea in hedgerows, use it to brighten garden corners where sunlight is scarce. It coexists peacefully with conifers and makes garden spaces appear fresher.
If you are seeking a plant that will deliver guaranteed results even without experience, smooth hydrangea is just the thing. It is reliable, beautiful, and generous with its blooms. Each summer it gives you luxuriant flowering that lasts until the first frosts, transforming even a modest garden into a true floral paradise.
