Delphinium 'Delphi's Hollands Glorie' - 2026

Delphinium 'Delphi's Hollands Glorie' is a striking perennial known for its rich royal blue flowers and upright growth habit. The tall, sturdy spikes carry single blooms along the stems, providing dramatic vertical interest in summer borders. Its dark green, lobed foliage creates a strong contrast, highlighting the vivid flower colour while supporting pollinators.

This cultivar thrives in well-drained, fertile soils and prefers full sun. It is ideal for the back of borders or mixed perennial beds, where the upright flower spikes can serve as a backdrop for shorter plants. Regular watering and staking during flowering help maintain its upright form and encourage abundant blooms, ensuring a long-lasting and decorative display throughout the summer.
