Delphinium 'Highlander Rainbow Sensation' - 2026

Delphinium 'Highlander Rainbow Sensation' is a striking perennial known for its fully double, frilled flowers in soft pink, lilac, and creamy yellow shades. The tall, upright stems carry the blooms above dark green, deeply lobed foliage, creating a dramatic vertical display in summer borders.

Ideal for adding height and colour contrast, it enhances the overall composition of cottage or formal garden borders.

This cultivar thrives in well-drained, fertile soils and prefers full sun to partial shade. Regular watering and staking during flowering help maintain upright form and encourage prolific blooms. Hardy and resilient, 'Highlander Rainbow Sensation' offers reliable summer colour and architectural impact, making it a standout addition to any garden where height, vivid colour, and ornamental structure are desired.
