Bring year-round structure and interest to your garden with pesticide-free perennials Eryngium Yuccifolium or Button Snakeroot – and these bee-friendly perennials are also a fantastic way to enhance biodiversity. With evergreen serrated leaves and oval white flowerheads that open to silvery-green, these unusual cottage garden plants combine beautifully with dahlias and echinaceas for a lovely late summer display. Don’t cut back after flowering, as the seedheads look stunning on frosty days.
