Eryngiums are very robust plants that grow well in full sun and can be tolerant to drought. The plants bear spikey cone-shaped flowerheads in blue and silver-grey tones. Spent flowerheads give winter interest to your border, so don’t cut them back straight away.

This clump-forming perennial with grey-green leaves bears small nodding red flowers from early summer that turn into extraordinary feathery seedheads. The foliage turns red in autumn which add interest later in the season. Geum Triflorum grows well in dry, free-draining soil and is drought-tolerant once established.

The flat flower heads of Achilleas are great for insects to land on and attract many pollinators, especially hoverflies. This variety is best grown in full sun and well-draining soil and looks great in the middle of a garden border. Division every three to five years will rejuvinate the plant.
