Asclepias tuberosa

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.

This evergreen perennial stands out because of it’s unusual look with its sturdy flower stems that are covered in whorls of pale yellow hooded flowers. After flowering these turn into architectural seedheads that give interest to your border in the bleak winter months and offer shelter for small insects.
