Common name

Type

Family
Hydrangeaceae

Hydrangea macrophylla ‘Pop Star’ is a compact, modern shrub hydrangea, valued for its abundant flowering and its ability to rebloom more easily than many classic varieties. It produces large, rounded inflorescences in vibrant colors, ranging from deep pink to blue depending on soil acidity, offering a strong visual impact despite its small size. Its overall habit is low, dense, and well-branched, making it particularly suitable for small gardens, structured borders, and container cultivation. The dark green, thick, and slightly glossy deciduous foliage effectively showcases the flowers throughout the summer. ‘Pop Star’ flowers on old wood and partially on new wood, which improves flowering consistency. Its excellent ornamental appeal makes it a reliable and decorative choice for semi-shaded areas.
