Lupins

Blue

Family Fabaceae
Name Lupinus
Common Name Lupins
Etymology
Lupinus From Latin lupus meaning wolf, referring to the misguided belief that lupins rob nutrients from the soil (because lupins grow in poor soils).

Lupin is a genus of nearly 300 species of legume plants. Some of them are annuals while others are short lived perennials. They originate from North America, Europe and Noeth Africa.

The most popular garden lupin is the Russell Lupin, available in almost any colour of the spectrum.

Lupins, like other legumes, can fix nitrogen from the air. Actually, it is the symbiotic bacteria that grows within root nodules that fixes the nitrogen. Because of this, lupins can usually grown as winter cover crop for the veggie garden.

Being able to fix nitrogen also means lupins will grow in poor soils, changing the chemistry of the soil over time. This can lead to new and different plants colonising the soils, often to the detriment of native plants.

Wild Lupins

Name Lupinus polyphyllus
Common Name Russell Lupins

Russell lupins is a strain bred by George Russell by crossing the perennial Lupinus polyphyllus with more colourful annual species to produce a perennial lupin with bright colourful flowers. This old favourite produces tall stately spikes of mostly bi-coloured flowers in the spring, usually with many colour variations on different plants. It sometimes flowers in the first season, but best flowering is from the second.

Almost all of today's bedding lupin varieties are variations and selections from Russell lupins. This includes the gallery series, a dwarf strain that is low growing.

Warning Lupins have been naturalised in a number of areas in the South Island. While this is very attractive, the Department of Conservation has deemed these to be exotic weeds taking over the natural vegetation. Do NOT spread lupin seeds to natural wilderness and conservation areas.

 Lupinus arboreus

Name Lupinus arboreus
Common Names Bush Lupin, Tree Lupin
Etymology
arboreus From Latin arboreus meaning resembling a tree.

This lupin was introduced from North America to stabilise sand dunes but has since made a nuisence of itself and is now considered a weed. Warning This lupin is very vigorous and will colonise large areas, crowding out native plants. It is also classified as a noxious weed.
