Achillea Milly Rock Mix

Achillea Milly Rock Mix is a compact yarrow selection prized for a long summer display of flat-topped flower heads held over finely divided, aromatic green foliage. Best in full sun and well-drained, moderately fertile soil, it thrives in normal to dry conditions and copes with drought once established; avoid heavy or waterlogged ground. Ideal for the front of sunny borders and informal, gravel-style plantings, it is highly attractive to bees and butterflies. Deadhead spent blooms to prolong the display and cut back faded stems in late autumn or early spring; fully hardy and reliable for Irish gardens.

To help give a clear sense of scale, the stone wall shown in our photos measures approximately 265cm in height. We also use familiar garden tools as visual references: a digging fork (110cm tall) and a hand fork (30cm tall). These are included purely as size guides to help you better judge proportions when viewing the images.
