Delphinium 'Highlander Blueberry Pie' - 2026

Delphinium 'Highlander Blueberry Pie' is a tall, hardy perennial admired for its dense spikes of vibrant violet-blue flowers with deeper centres that bloom from mid to late summer. The striking flower spikes rise above clumps of finely divided dark green foliage, creating dramatic vertical interest in borders, cottage gardens, and mixed perennial plantings. Its nectar-rich blooms attract bees, butterflies, and other pollinators, adding both ornamental beauty and ecological value.

Thriving in full sun to partial shade with fertile, well-drained soil, Delphinium 'Highlander Blueberry Pie' benefits from staking to support its tall flower spikes. Cutting back spent stems helps maintain a tidy appearance and can encourage prolonged flowering in favourable conditions. Hardy, long-flowering, and relatively low-maintenance, this cultivar provides a striking display of summer colour and architectural structure, making it an excellent choice for dramatic garden borders.
