have you planted them out too early when they are too small?
lupins have a few pest enemies that go to town on them. Their own "special" aphid and snails esp love them
I find lupins grow beautifully here...in fact one I divided in early summer is now producing a purple spike already. I grow them in pots before I plant them out; at least to fill a 3 litre pot. They are then strong and fairly resistant to adverse comditions.
Why go for "dwarf" lupins though? The regular lupins are so distinctive, eye catching and beautiful. Dwarf versions of plants often seem to disappoint me because they lose something else apart from size.
I suggest you buy lupins in 9cm pots in very early spring....they are cheap and available in the gc's or online. They will grow fast at that time. I pot on then into 1 litre pots, 2 litre and then into 3 litre pots and by mid June they are soon to flower. They will cope with snail attacks ....still check for them though....and flower profusely.
don't give up on growing lupins......wouldn't be without them here DimWit
oh! Final thought. Lupins do not like too much lime. On an alkaline soil or even on a neutral soil they benefit from a couple of sprays of epsom salts in spring
