Lupinus perennis or wild lupin is native to the light pine and deciduous woodlands of the east coast of the United States (from New England down to Texas) where it can form huge colonies.
In late spring and early summer it produces violet blue flowers on tall stems.
For light understory, near trees or dune gardens.
Easy to grow in the sun or light shade in poor, sandy acid to neutral soil. Re-seeds freely. Avoid heavy, clay damp soils.
Height: 110 cm. Hardy.
"This is an authentic botanical species! We have included Lupinus perennis because it can provide great ornamental interest and become naturalised in prairie gardens with poor, sandy soil (coastal regions). Try it out and let us know how you get on!"
PS: If perchance you spot the Karner blue butterfly (Lycaeides melissa samuelis), let your local newspaper know! Karner blue can only live on this wild lupin and is a rare, at risk species. So we might deduce that it has crossed the Atlantic to visit your garden :-))
