Lupins, including Russell lupins and blue lupins are garden flowers that have escaped and are now found wild in many parts of New Zealand.
Lupins have attractive spikes of blue or multi coloured flowers. They can be seen on the roadsides of many parts of New Zealand.
Tree lupins can grow to 3 mtres tall. They are not readily eaten by stock and can grow in pasture and paddocks. Some species of lupin can be toxic to stock. The yellow flowered tree lupin has a strong scent but it's blue cousin is not scented.
Alternatively cut down the tree lupin and immediately apply Invade Gel to the cut stump.
