What is this Plant?

The plants you're starting look magnificent! One makes me long for lemon pound cake. I wish you luck with your search for A. palaestinum; it's a stunner. And if you should end up with a bumper crop of Giant Echium, I have a place for one!

 

Let me see if I can get some of the seeds to germinate, and I can give you actual plants if you like. Of course, if they set seed in their second year, given the size of those inflorescences, you'll likely have a lifetime supply of your own after that!
