Centaurea Species, Bachelor's Button, Cornflower

I love cornflowers, but when planted some from seed (on two different years now) I get lots of really tall green plants, but no flowers! ...Read MoreWhat am I doing wrong? Please help.
Thanks

Centaurea cyanus is also known as garden cornflower. It is native to Europe which has naturalized throughout North America. It can be f...Read Moreound growing in all US states including Hawaii. In Texas, it grows in the wild in 11 counties. Seeds should be sown at a depth of 1/8 inch. Cornflower blooms retain their bright colors when dried and make great additions to dried flower arrangements.

Only Sweet William were second to this in mixed seeds - too bad I don't have any Bachelor's Button left - limited sun those days and lots of perennials.

I have not had trouble transplanting cornflower either. Those who wintersow will know they transplant beautifully (and early!) using the ...Read More"hunk o seedlings" method.

This plant grows wild all over the place here. It is one of those "weeds" that doesn't seem to bother any one or anything.

However, you won't likely find it outside of human disdurbance of the ground. You won't see it much in the forest or sagebrush flats, but somehow it looks perfectly at home with sagebrush and the blue of its flowers goes so well with the sage. I never really thought about "growing" this because it was already "growing", but now I can see potential for making it grow in places where it might make more of an impact, color-wise. I'd really never thought of it that way before. It just grew where it grew.

Cornflower is most noted for its true blue flowers. Though now other cultivars (black pink and white) have popped up. The black is a dee...Read Morep burgundy color. My favorite is still the blue. Cornflower foliage is also decorative. It is silvery and slightly fuzzy. My cornflowers often get taller than noted in many books etc. Mine this year are about 4 feet! :) One of the easiest annuals to grow. :)

Love this plant. I do not understand why some have trouble moving them.

The rabbits really like them. After mowing them down twice,I was forced to "cage" them.

I had volunteers this year,naturally out of the bed, I had saved a few seeds and they have taken off really well this year and I expect similar results
good luck to all

Self sows and comes back for years.

This plant is easily grown and multiplies simply by plucking the dry heads of the flowers off the plant and crumbling them on the ground ...Read Morebeneath it (or wherever you want them to grow.) They are excellant for dry lasting flower arrangements and hold their colours well under those circumstances.

On the downside, in order to maintain a nice looking plant they require deadheading on a regular basis, and as they age and get larger they will sometimes begin to look dry near the lower 6 inches or so of the plant.

Bachelor's button does not like to be transplanted, so it is important to sow seeds in the place where you want your plants to grow.
