Position: full sun or partial shadeSoil: light, moderately fertile, humus-rich, moist but well-drained Rate of growth: average Flowering period: July to SeptemberHardiness: fully hardy
Dense and upright in habit, the grey-green foliage contrasts perfectly with the rose-tinted, purple flowers, which are attractive to butterflies and bees. Also, providing it gets plenty of sun (and it's dead-headed regularly) 'Schwellenburg' will continue to flower over a long period - offering lashings of late summer colour.
Garden care: To prolong flowering remove the flower spikes as soon they start to fade. Cut back all the stems after they have finished flowering and apply a generous 5-7cm (2-3in) mulch of well-rotted garden compost or manure around the base of the plant in spring.
