Aconitum napellus 'Blue Valley' - 2026

Aconitum napellus 'Blue Valley' is a striking perennial with tall spikes of deep blue, hooded flowers that bloom through the summer months. Its dramatic vertical growth and vibrant colouring create an impressive display in borders, particularly when planted among lighter perennials for contrast. The finely divided, glossy dark green foliage provides attractive texture, even when the plant is not in bloom.

Thriving in full sun to partial shade, this cultivar prefers moist, well-drained soil and benefits from a sheltered position to protect its tall stems. Hardy and robust, it is suitable for mixed borders, cottage-style plantings, and wildlife-friendly gardens. While highly ornamental, all parts of the plant are extremely toxic and must be handled with care. Its showy flowers also attract pollinators, extending seasonal garden interest.
