Bachelor
Button
Centaurea |

Description:
This flower is simple to grow and maintain. It will do well if you plant it
in a sunny, well-drained location. If there is too much shade it will become
weak.
A great plant to share with friends! The seeds germinate quickly and can
easily be gathered up all summer. Plant with Stokesia,
Campanula and
Gaillardia. Can become invasive. |
