Solved PlantID please - what have I bought?

I bought this plant at the farm shop in Cirencester for £2 in April without name on it. It's now almost 2 meters/6,5 inches high.

Grateful for all suggestions. I tried a search in the internet but have run out of ideas how to describe it.



and the leaves

 

Looks like Ammi majus, aka False Queens Anne's Lace.

 

Wonderful @BobTG

I tried to grow them but failed. I call myself lucky to have bought what I wanted.

 

Very nice too!!.....excellent plants for pollinators .

 

I sowed some seed last Autumn and I'm thrilled with them - they are way taller than me and sway so beautifully in a breeze. The flowers are just beginning to open.

 

Thanks for the tip. I will try my seeds then in Autumn. I did it in March and nothing came up....
