A sub-shrub with highly scented flowers. Still not often seen in gardens in the UK, this is well worth growing and becomes a talking point. Produces branching stems from a stout trunk. Fragrant bi-coloured blue flowers, much loved by bees and butterflies are produced throughout the summer.
Fully hardy and remains semi-evergreen in mild winters.
Common name: Blue Tree Lupin
The Tree Lupin was brought from California in 1793 and is one of the parents of the garden lupin we know today.
