Buddleja davidii 'Empire Blue'
- A true showstopper, this buddleja delivers beautiful, violet-blue flowers with bright orange eyes and a sweet fragrance. This characteristic ensures it stands out as a true horticultural masterpiece.
- As it establishes, this buddleja forms an incredibly vigorous, fast-growing, and gracefully arching growth habit. It is beautifully complemented by its silvery-green, lance-shaped deciduous leaves highlighting the vibrant blooms, making it highly rewarding to cultivate.
- For the best performance, position this buddleja in full sun and well-drained soil, responding incredibly well to a hard spring prune. Despite its highly ornamental appearance, it is reassuringly robust and easy to care for in the UK.

- This is a buddleja with a brilliant story: buddleja was named after the Reverend Adam Buddle, an amateur English botanist. Introduced from China in the 1890s, it quickly became a cottage garden staple.
