Yes Kaz809 you stand a good chance depending where in the world you are. If you're in the UK then you can grow your young plants in a cold frame although I've grown them outside in their pots in a sheltered spot so long as we don't get a very hard winter.
They should grow on for you now, pop them outside somewhere sheltered to get hardened off, there's still a bit of time for them to grow before the winter sets in. They should flower for you next year and you can plant them into their spot in springtime.
By the way, I've grown lupin from seed for manys a year and sometimes they're a success other times the slugs get them. Good luck.
