50 Seeds Blue Bird Delphinium - Tall Spikes of Sky Blue Blooms - Hardy Perennial for Cottage Gardens & Cut Flowers

Blue Bird Delphinium brings dramatic height and vivid sky-blue spikes to any sunny border. This hardy perennial is prized for its stately floral columns, each densely packed with ruffled blossoms that attract pollinators and make stunning cut arrangements. Grown from fresh seed, these plants will establish strong crowns and return year after year, offering a classic cottage garden statement.
Perfect for the back of a sunny bed, mixed borders, or rows for cutting, these delphiniums bloom in early summer and may rebloom if spent stalks are removed. They pair beautifully with roses, peonies, and ornamental grasses, and their cool blue tone adds depth to pastel palettes. Provide rich, well-drained soil and shelter from strong winds for best performance. As a cut flower, spikes last a week or more in fresh water.
