Heliopsis helianthoides var. scabra

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 deciduous perennial can grow up to 1m tall and attracts butterflies, which is why it’s also called butterfly weed. Clusters of flat bright-orange flowers in midsummer are followed by long seedpods.

This native wildflower bears large white or pink flowers with a purple lower lip that sit on honey-scented foliage traditionally used in “Maybowl” beverages and retaining its fragrance once it’s dried. Melittis Melissophyllum is a very tough plant and can survive long periods of summer drought once it’s established.
