Set of 3 or 6 Delphinium Dark Blue Black Bee Tall Hardy Perennial Plants, Summer Flowering Border Plants, Outdoor Garden Ready, 1 Litre Root-Ball

A striking addition to any garden border, the Delphinium Dark Blue Black Bee produces tall, elegant flower spikes in a rich, deep blue with a contrasting dark centre, known as the 'bee'. This classic cottage garden favourite is a hardy herbaceous perennial that returns year after year, creating dramatic vertical interest and attracting pollinators throughout the summer months.

Each set includes 3 or 6 established plants supplied in 1Ltr root-balls, ready to plant straight into the garden or a large container. These vigorous growers will reward you with magnificent spires of densely packed blooms, perfect for adding height and colour to mixed borders, cutting gardens, or as a focal point in any planting scheme.

For the best results, plant in a sheltered position with fertile, well-drained soil and provide support as the tall flower spikes develop. Deadheading after the first flush of blooms can encourage a second, smaller display later in the season.
