Delphinium Elatum Guardian Blue – Cutting Variety 

Delphinium Elatum ‘Guardian Blue’ is one of the most reliable, richly coloured and dramatic early-season delphiniums you can grow. With its tall, elegant spires covered in velvety deep-blue blooms, it brings instant height, structure and that classic cottage-garden wow factor — while producing beautifully long, straight stems ideal for cutting and arranging.

These are cutting-grade Delphinium Elatum Guardian series plants, grown here in South Devon in peat-free compost, and supplied as 6 strong jumbo plug plants. We pack them in our biodegradable/reusable hado bags, which protect the roots and keep the plants hydrated during delivery.

‘Guardian Blue’ is particularly loved by florists because of its saturated blue colour, excellent stem quality and earlier flowering compared to many other tall delphiniums. Whether you’re filling borders or vases, this is one of those plants that makes your entire garden feel more dramatic and beautifully structured.
