California,
United States 
Can someone tell me how to prune a Echium Fastuosum? Do I cut off just the flowering portion or do I cut the stem off as well, to the trunk of the plant? Thank you.

I prune mine to just below the flowers. Sometimes you can get a few late flowers. Also, wear gloves as there are fine hairs on the stems that can be irritating. I also have found that pruning needs to be done before seed is set - the seeds germinate very easily.

remove the spent flowers . I'd take the flower stalks back to the main stem personally.
welcome to GoY too.
