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.

I bought some red sunflower seeds from this website. I also bought seeds from the big box store. The seeds I bought from this website sprouted first and look very robust. I am ordering more. Look for the next review once they bloom!!!
The seeds arrived quickly but we did not receive part of our order. We are still waiting for the ones we received to grow so too early for full review.
