Achillea ptarmica ‘The Pearl’
Achillea ptarmica ‘The Pearl’ bears informal heads of semi-double, pure, button-like white daisies. Similar in habit to gypsophila, it’s perfect for growing in an informal or cottage garden scheme, or as a foil for more colourful plants. It makes a wonderful cut flower. It’s particularly attractive to hoverflies. For best results, grow Achillea ptarmica ‘The Pearl’ in full sun in well-drained soil. Cut back faded blooms to prolong flowering. Divide clumps every three to five years, and never allow plants to become waterlogged.
