Great Hercules is a show-stopping dinnerplate dahlia admired for its commanding garden presence and colossal, visually impactful blooms. A vigorous, tall-growing variety with exceptionally strong stems, it effortlessly supports its massive flower heads, making it a spectacular focal choice for premium cutting gardens and dramatic statement arrangements.

This variety features enormous, beautifully formed, and slightly ruffled decorative blossoms that can stretch up to 20cm to 25cm across. Its striking colouring showcases an exquisite blend of bright, golden-orange and warm bronze tones, softly brushed with hints of apricot and delicate peach-pink highlights. The broad petals carry a slightly swept-back appearance that gives the giant, luminous heads a sense of elegant fluid movement rather than feeling heavy in the landscape.

An exceptional cut flower with true theatrical flair, Great Hercules pairs beautifully with deep maroons, rich purples, and warm metallic autumn palettes, and is loved for both its monumental beauty and tireless, late-season reliability.

Features:

  • Type: Decorative

  • Bloom Size: Giant / Dinnerplate (approx. 20cm – 25cm)

  • Height: Approx. 1.0m – 1.2m

  • Best for: Statement cut flowers, focal bouquets, and back-of-border planting

  • Colour: Golden-orange, bronze, and apricot-pink tones

Growing Dahlia Tubers in New Zealand

Below are some answers to frequently asked questions about growing dahlias. You can also download our handy Dahlia Growing Guide here.

  • Plant dahlia tubers in New Zealand from late spring once the risk of frost has passed and the soil has warmed. In most regions, this is typically between October and December.

  • Plant tubers horizontally about 10 to 15cm deep in well-draining soil, with the growing eye facing upwards. Choose a sunny position and allow enough space between plants for airflow as they grow.

  • Dahlias grow very well in New Zealand conditions, especially in sunny, sheltered spots with free-draining soil. They are well suited to both home gardens and cut flower growing.

  • Yes. All Piako Botanicals dahlia tubers are selected for their performance in the garden and as cut flowers. Many varieties produce long, strong stems that are ideal for harvesting and arranging.

  • In colder or wetter areas, lifting tubers over winter can help prevent rot and improve performance the following season. In milder regions, they can often be left in the ground if drainage is good.

  • All tubers are grown, lifted, divided, and stored by hand on our Waikato flower farm. We only sell varieties we grow ourselves, so you can plant with confidence.
