Salvia nemorosa ''Sensation Rose' (Sensation Series)' - Throughout summer, spikes carry masses of rose pink flowers, each sitting within a deeper purplish-pink calyx. Their compact, tidy habit makes them ideal for containers and window boxes, as well as creating colourful drifts towards the front of a sunny border.
Erigeron karvinskianus 'Mexican fleabane' Masses of small daisies, emerging white, then turning pink, with yellow centres, give this plant an unusual, two-tone effect. It has a long flowering period, from May to October, and is amazingly versatile, being low-growing, happy in su sun or partial shade and thriving in any well-drained soil. It's also tolerant of coastal conditions. Try it as an edging plant in a mixed border, alongside paths, in a gravel garden or spilling over walls.
