It's a perennial variety https://www.rhs.org.uk/Plants/248688/Lupinus-Beefeater/Details but they're apparently not the most long-lived. They do OK for me but I have light, slightly acid soil which is apparently what they prefer. Watch out for slugs on the new growth, and those nasty fat grey lupin aphids (squish them or blast with water the moment you notice any).

Thanks. I don't have much space in the border, can I grow it in a pot ? If yes, what kind of compost should I use. I have some john innes 3, can I use that ?
They apparently do prefer lighter soil. Maybe you could dig in some grit to lighten it a bit? Or if you really want to use a pot, make sure it's a good size, and deep. Also the flowers aren't all that long-lasting so really better in a border with other things that will take over later in the season.

I grow lupins on clay and they used to die every winter until I tackled the slugs because they were eating all the new growth before I could even spot it. However, the lupins don't last as well or as long as they would on lighter, drier soil so I save seed and grow some new ones every year as replacements.
