This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring. Position: full sun; Soil: moist, well-drained; Rate of growth: average; Flowering period: June to September; Hardiness: fully hardy This versatile, sun-loving perennial will add colour as well as structure to herbaceous borders and pots, but it also looks right at home in a prairie, gravel or wildlife-friendly setting. Their flattened flowerheads are a fab colour, starting off a rich terracotta, but fading to soft biscuit tones as they mature over the summer. The plate-like flowerheads contrast particularly well with spikey or upright shapes – so salvia, veronicastrum and eryngium makes great partners; Garden care: Achilleas do not like wet soil. Stake using bamboo canes or brushwood before the flowers appear. Cut down to the ground in late winter, but resist the urge to do this earlier, as the seed heads look lovely in the winter. Pull out seedlings as they appear as they rarely match the parent plant, and lift and divide large clumps in late autumn or early spring.
