The World’s Best Hydrangea Gardens: A Florist Guide

Hydrangeas, with their spectacular blooms and stunning color variations, are among the most beloved flowering shrubs in the world. From delicate lacecaps to dramatic mopheads, these plants create breathtaking displays in gardens across the globe. This flower delivery guide explores some of the finest hydrangea collections and where to experience them at their peak.

Understanding Hydrangeas

Before exploring the gardens, it’s helpful to understand what makes hydrangeas special. These deciduous shrubs produce large clusters of flowers from early summer through fall, with colors ranging from pure white to pink, blue, purple, and even green. The color of many varieties depends on soil pH—acidic soils produce blue blooms, while alkaline soils create pink flowers.

• Historic cultivars versus modern hybrids
• Garden design techniques for incorporating hydrangeas

Continental Climates (Northeast US, Central Europe): Cold winters encourage vigorous spring growth, but gardeners must select hardy varieties.

Temperate Asian Gardens (Japan, Korea): Traditional garden design incorporates hydrangeas as essential elements rather than specimen plants.
