Nice garden flower, don't know what it is

Several years ago I got some seeds from another garden for this plant. I love it. It's established now and I've looked at garden centres and kept my eye open for a name. After all these years I still don't know what it is and I give up! Any help is appreciated

 

Another photo. It grows to about 2 feet tall.

 

@flowery prose good morning, have a look at Malva alcea.

 

It did remind me of hollyhock (esp seed head) but its leaves are so different. Malva alcea, not Alcea rosea. Yikes the Latin alceas :) but in that family.

Thank you very much!
