Description
Hydrangea 'Hercules' lives up to its name with towering, panicle-shaped blooms that command attention from summer right through to autumn. This giant panicled hydrangea produces flower heads up to 40cm across, starting as crisp white-green and gradually developing a delicate rosy blush as the season progresses. Hydrangea 'Hercules' has a robust, upright habit, growing to around 1.5–2 metres in height and spread, making it a show-stopping feature in borders, patios, or even as a focal point in larger gardens. Each bloom of Hydrangea 'Hercules' seems to defy gravity, adding drama and elegance in equal measure, while the soft blush tones bring a gentle warmth to the greenery.
Beyond its spectacular flowers, Hydrangea paniculata 'Hercules' is impressively hardy and low-maintenance. It thrives in sunny to semi-shaded spots with moist, well-drained soil, making it a reliable choice for UK gardens where structure and season-long interest are key. The sheer size and longevity of Hydrangea 'Hercules' flowers mean it pairs beautifully with contrasting foliage or other perennials, providing a lush backdrop for summer and autumn planting schemes. Whether you want a dramatic statement plant or a dependable garden star, Hydrangea 'Hercules' delivers towering elegance with minimal fuss, offering a bold, long-lasting spectacle that will be admired year after year.

Useful information
-
Soak the Hydrangea 'Hercules' roots in water for 3-6 hours prior to planting
Plant your "Giant hydrangea" bare roots into temporary pots with a multipurpose compost within a week of delivery and grow-on in a sheltered spot outdoors
Choose a pot which comfortably fits the bare roots. Some have a noticeable crown which should be just below the soil surface with any top growth exposed. Some varieties are a length of root which should be planted lengthways and shallowly (1-2cm deep).
Plant out into borders or permanent containers in late spring or early summer once in full growth. Choose a position in sun or shade depending on the variety.
