Elizabeth.........depending what type you have, I wouldn't say it is abnormal.
The basic ones can certainly reach the size you mention without too much trouble
The wild pink ones in my garden grow anything from 3 to 8 feet.
Well I should find out next summer cos I've got foxgloves coming out of my ears right now
I find they can seed and sow without any input from me
On any one flower spike there will be seed capsules which are immature at the top, others that have already escaped at the bottom, and ready-to-collect ones in between. Collect some capsules from the middle, place in a paper bag, shake and hey presto you have ten million seeds. They are minute so only need sprinkling where you want them to germinate, including your seed tray. No need to cover.
