so pretty
really amazing flower – and cool name too. 🙂
I think its common name is very cute!
I grow this in my garden, but I’ve never heard it called Bachelor’s Button before, love that!
Your picture looked similar to what I have grown, but not quite, so I looked it up online and discovered there is definitely a difference between your picture of “Centaurea montana" and the garden variety, “Centaurea cyanus," that is typically sold as Bachelor’s Buttons or, less often on seed packets, cornflowers. I learned something today about the varieties, so thank you! I have always grown “cyanus" in my garden. It reseeds faithfully, becoming a pest so that I have to weed it out of everywhere. Fortunately, it’s an easy plant to pull. I love that, once in a while, a different color I didn’t anticipate will show up some years! Such a fun, carefree flower to have in my messy gardens.
As long you enjoy them, they are good plants. 🙂
Also known as knapweed!
So many plants has so many different common names! That is why the scientific name is the real name.
