How to Grow
It is most ideal to start these seeds indoors before transplanting outside. Plant the seeds indoors 8-10 weeks before the last expected frost. Sow the seeds into flats or small pots. Keep the seeds moist until germination, which will occur within 2-4 weeks under proper conditions. Once seedlings are established and frost danger has passed, they can be transplanted directly outdoors. Cornflower plants should be fertilized with a slow-release fertilizer. Keep the soil evenly moist, and pinch plants to encourage bushier growth.

Cornflower (Centaurea Montana) - For a true blue flower, start these seeds, and enjoy not only the blue shade, but a perennial wildflower as well! Native to damp meadows in the European mountain ranges, this perennial Centaurea is commonly called Mountain Bluet or Mountain Cornflower, and it is rugged and hardy, growing in most soil types and climates. The vigorous clump-forming plant has silvery-green foliage and stems that are slightly hairy. The blooms are large, solitary, and fringed and are excellent for cutting. The plant does best in moisture retentive soils. Care includes removing spent flowers after blooming. The cornflower plants can be trimmed back hard after blooming. Mountain Centaurea is known for self-sowing, so deadheading is needed if spreading is not desired.
