Both Lupins and delphiniums are easy from seed, provided they are protected from slugs (which seem to regard them as a delicacy!) We grow both in England on clay soil, but your windy hill, Jo Ann, may be a problem for delphiniums as you say.
On seed sending from England, apparently it's possible to get a licence to import small lots without the need for any expensive phytosanitary certificate.

Alternatively I can just send them - I've sent small quantities of seed in the past and three out of four said they arrived (took 3-4 weeks, though!)
So if anyone would like some lupin seeds, let me know. We get our lupins from West Country Lupins in England - they have some lovely colours, but of course with seed you never know if the plant will look exactly like the parent!
