Yes it is possible to do that. After the flowers fade you'll see seed pods forming. In a while they will turn brown and there will be holes in the tops of them. The seeds can be shaken out.

Thank you all. Sterogram, I do have a picture of Geoffrey, my wooden giraffe but not sure how to get the pics from my kindle fire onto this site.

Lol Kitt, you needed to add this comment underneath mine on the original thread!

Anyway if your garden's anything like mine once you've had foxgloves they go on seeding themselves (unless you deadhead them before the seeds are ripe) follow Hywel's advice and you should win both ways.

Can't help with the Kindle - my pics ate all on my laptop. But if you access Goy from your Kindle its just a matter of going to your profile page, and following the instructions. Ask again if you're baffled as lots of folk here use tablets.
