Heliopsis helianthoides var. scabra

This lovely cottage garden plant has spikes of purple-eyed white flowers that shoot up from glossy dark evergreen foliage. Flowers emerge from early summer and bloom right the way until early autumn. This plant is a biennial, so avoid cutting back spent flowers to allow them to self-seed.

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 salvia shows velvety purple and plum coloured blooms from spring to autumn and sometimes even until the first frosts. Grown in ideal conditions in well-draining soil and full sun or partial shade it will keep its foliage in mild winters and can tolerate very low temperatures with some winter protection. Plant in a patio container or near seating areas to enjoy the minty-blackcurrant scent from the foliage.
