Hydrangea Macrophylla ‘Blue Danube’

Hydrangea are one of the easiest shrubs to grow, and will perform extremely well in gardens up and down the UK. They will grow in sun or shade, and in most different types of soil. Although, remember that an acidic soil will give blue flowers, whereas an alkaline soil will produce pink blooms!

Hydrangea ‘Blue Danube’ has been specially selected for its deep blue flowers, with compact growth yet large, showy flower heads, 20cm (8″) across. Grow in mixed borders, or in patio containers. Height and spread: 1m (39″).

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 blue flowers will take on a pink hue as they fade through autumn and may also be affected by alkaline tap water or soil. For the deepest blue flowers right through the season we recommend the use of Hydrangea Colourant
