Deer don't eat lupines, deer mow my lawn, lupines are a member of the pea family and related to Broom bushes another widespread wildflower in my area.
Lupines are not bee's favorit. If you look for lupine honey, you will not find that product.
True, but lupine is still a flower buzzing with bees while in bloom. My apiary is forest with poppies, bee balm, wisteria, gladiolas, blueberries, butterfly bush, echineasia, sunflowers, cherries, strawberries, lupines, lavender, salvia, clematis, honeysuckle, hops, dogwood...there is no way to guarantee any honey is single forage crop unless that was the only crop for at least eight miles. Not even in the worst mass planting of berry crops is this the case. Single forage crop honey in Canada has to bee at least 5o percent single forage to be labelled as such. That being said, I do agree that lupines are probably not a plentiful source of nectar because they grow so scattered as most wildflowers do. I'm a fan of any perennials that spread and need little care.
