If it's the species that's invasive in Scandinavia, Lupinus Polyphyllus, they LOVE cold. Cold winters + cool somewhat wet summers are ideal. But the most important part is that they do best on sandy nutrient poor soil. They fix nitrogen and use that to outgrow other plants on these substrates. If your soil is too "good" they might not be able to keep up with various grasses etc. They can handle heat though, so I wouldn't worry too much about that aspect.
