Centaurea moschata “Imperialis” (syn. Amberboa moschata)
Imperial cornflower, musk centaury, musk cornflower, amber flower: unlike the common cornflower, this one is above all a fragrant flower. Its large, shaggy flower heads release a musky, sweet fragrance that scents an entire bed—a rare quality among annuals, and one that explains its presence in all the old-fashioned cottage gardens of the past.
Characteristics:
-
Large fragrant flowers: shaggy flower heads ranging from pure white to deep pink and violet, highly scented.
-
Long flowering period: from June to September, on slender stems 50 to 70 cm tall.
-
Vintage charm: an annual from old-fashioned gardens, now rare in modern catalogues.
Sowing advice:
-
Exposure: sunny.
-
Soil: light, well-drained, ordinary to poor, preferably alkaline. It tolerates relatively dry conditions once established and requires no fertilization: in overly rich soil, the stems become elongated and flop.
-
Method: no stratification required. Sow directly in the ground from March to May, or from February in pots under cover. Germination is quick, taking 7 to 15 days at 15-20 °C. As its taproot does not tolerate late transplanting well, sowing in place is preferable. See how to sow your seeds.
Care advice:
- Water moderately. Remove faded flowers to encourage further flowering, while leaving a few flower heads for self-seeding.
- Stagger sowings every three weeks to extend flowering through September.
Harvesting advice:
- For bouquets, cut the stems in the morning, when the fragrance is most intense and the flowers have just opened.
Beneficial combinations:
Benefits for biodiversity:
- Its powerful fragrance and large flower heads are particularly attractive to butterflies, as well as bees and bumblebees.
- Its seeds feed goldfinches in autumn if a few flower heads are left to mature.
Uses:
- Flower beds, borders, and cottage gardens. Above all, it is an excellent cut flower: its bouquets scent an entire room.
Symbolism:
Like all centauries, it symbolizes delicacy, nostalgia, and the subtlety of feelings. It evokes old-fashioned, romantic gardens.
Harvesting your own seeds:
Leave a few faded flower heads to turn completely brown on the plant, then shake out the seeds over a container: the tufted seeds come away easily. See how to store your seeds.
