Echinacea, with a twist

We love this unusual green echinacea. It’s called ‘Green Twister’ and it flowers from June to September, preferring sun in a humus-rich, well-drained soil. Butterflies love it too. H60cm (2ft) S40cm (16in). It’s so new that plants are in short supply, but it’s currently available from J Parkers at £5.99 (0161 848 1100; www.jparkers.co.uk) Love this plant? Or is green echinacea a step too far? Let us know
