Delphinium ‘Guardian Blue’ is a spectacular and reliable variety that brings a sense of regal elegance to your garden. Known for its rich, true blue blooms, this tall, robust perennial is perfect for adding height and dramatic colour to your borders, beds, or cottage gardens. The striking blue spikes of flowers are complemented by deep green, finely cut foliage, creating a visually appealing contrast that lasts throughout the summer months.
This low-maintenance, disease-resistant variety thrives in full sun and is a magnet for pollinators like bees and butterflies. Whether you’re looking to brighten up your garden with striking colour or need a reliable, easy-care plant, Delphinium ‘Guardian Blue’ is an ideal choice for lasting beauty and garden charm. Height: 1.2m (4′). Spread: 75cm (30″).
Plant height and spread is seasonal therefore we list by pot size rather than a defined plant size. The height and spread of the plant delivered will vary depending on the season, meaning arrival images are an indication only. The Guardian series of delphiniums have been bred to flower earlier than other varieties. Pot up plants into larger containers. Gradually acclimatise to outdoor conditions for 7-10 days and plant out once all risk of frost has passed. When growing Delphiniums, choose a sunny position that is sheltered from strong winds, on moist, well drained soil. Protect young delphinium plants from slugs and snails.
