Helianthus tuberosus - 2026

Helianthus tuberosus is a hardy perennial valued for its bright yellow daisy-like flowers with golden centres that bloom from late summer into autumn, creating a long-lasting and cheerful display. The tall, upright stems rise above coarse, green foliage, adding height, structure, and late-season colour to borders, cottage gardens, and naturalistic plantings. Its flowers attract bees and butterflies, supporting both ornamental and ecological value.

Thriving in full sun with moist, fertile, well-drained soil, Helianthus tuberosus is low-maintenance and easy to grow. Deadheading spent flowers encourages prolonged flowering, while cutting back in spring maintains healthy and vigorous growth. Hardy and resilient, this species delivers reliable late-summer to autumn colour and pairs well with grasses or other tall perennials.
