How to care for Cephalaria gigantea:
Plant in full sun and well-drained soil that’s been enriched with plenty of organic matter to support strong, upright growth. Space plants well apart to allow good air circulation, especially in heavier soils. Water during dry spells in the first season to help establish deep roots, but once settled, the plant becomes better able to deal with periods of drought.
Deadhead regularly throughout summer to encourage continuous flowering and prevent self-seeding. In autumn, once flowering has finished and the foliage dies back, cut the plant down to ground level and compost the spent stems. Giant scabious may benefit from staking in exposed sites to prevent flopping.

Please note:
This perennial dies back to below ground level each year in autumn, then fresh new growth appears again in spring.
