Grow centaurea in any fertile, well-drained garden soil, in a sunny position.
Dead-heading is recommended for both species to prolong the flowering period.

Germination should take around four to five days.
Week 16; When seedlings are large enough to handle prick out into pots/tray or boxes of potting compost and grow on in a cold frame until planting out time.
Week 21; Plant out cyanus 300 (12") apart.
Week 40; Plant out montana 300 (12") apart.
Established plants of montana can be divided and planted out immediately at this time.
