Probably everyone is familiar with the blue pea-like flower of the wild lupin (occasionally white or pink) so I will emphasize its other qualities because it is an extremely useful plant. It enhances soil fertility by fixing atmospheric nitrogen into a useful form and it is very attractive to a large range of native bees, hummingbirds – most notably it’s the only larval host for the Karner Blue Butterfly caterpillars! Birds and small mammals eat the seeds.
Very adaptable, and particularly useful on sandy soils & other difficult locations. The only defect noted is that it will reseed around.
Germination: sown in late fall outside or in the spring indoors: in this case soak the seeds one day before sowing, and place at +/- 20˚C.
