Centauria Cyanus - Bachelor Button - Polka Dot Mix Seed grows 2 to 3 feet and used to grow wild in cornfields and was considered a weed by farmers. It likes full Sun and also attracts butterflies and pollinators. They make a great cut flower and are grown for that as well as being grown for an ornamental.

I urge anyone buying seed to do their homework on germination, I have not raised and cannot raise many of these plants as I am sub-tropics here in St Augustine,Florida. All seed are NOT alike!  There are so many different factors in germination and not doing a search is throwing your money away. I want everyone to be successful when growing your flowers from seed it is the most rewarding experience in Gardening and you can do it, if you give the seed what it needs to grow. I always check 3 sites of info to choose how I will go about it. It is not hard to do, if you do it right! 
SEED GERMINATION TIP!!!!!!!
ONLY GERMINATE A SMALL PORTION AT A TIME.
DON'T PUT ALL YOUR MONKEYS IN A BARREL.
Good Luck and Happy Planting!!!!
