There are several Yarrows for the back or the middle of the border. Achillea ‘Cerise Queen’ is a particularly colourful yarrow, bearing cerise pink flower heads with dark margins and paler colouring towards the centre. It’s perfect for growing towards the middle of an ornamental border or wildlife garden, and is also ideal for growing in gravel gardens. For best results, grow Achillea ‘Cerise Queen’ in full sun in well-drained soil. Divide clumps every three to five years, and never allow plants to become waterlogged.
