Lupinus x regalis (Russell Lupin - Purple)

Hi Jonathan

This plant is growing on a reclaimed colliery site that has been turned over to a community woodland by the Land Reclamation Trust. A pink variety of Lupin was found not too far away. My impression was that they had either been planted or grown from seed that had been intentionally sown

Ah, I see, yes, very likely

Ah, I see, yes, very likely sown deliberately to help add some nitrogen to the soil. Lupins, like all members of the pea famliy have root nodules that contain bacteria which can turn gaseous N from the air into soluble compounds that plants can use.
