Species: L. nootkatensis
Lupinus nootkatensis, the Nootka lupine, is a perennial plant of the genus Lupinus in the legume family, Fabaceae. It is native to North America. The Nootka lupine grows to 60 cm tall. Late in the 18th century it was first introduced to Europe.
The Nootka lupine is common on the west coast of North America, and is one of the species from which the garden hybrids are derived, being valued in Britain and other North-European countries for its tolerance of cool, wet summers. It grows along roadsides, gravel bars, and forest clearings from the Aleutian Islands, southcentral Alaska, and along the Panhandle to B.C. Rigorous self-seeders as they are, lupine can often be seen along roadsides and in open meadows, their bright blueish purple flowers catching ones eye from quite a distance. Their long tap roots make transplanting difficult, so sowing seed is preferable.
A member of the Pea family (Fabaceae), lupines form seeds in fuzzy pods that may be attractive to children. The seeds of the lupine can be toxic, though toxins flush through the system quickly and are not cumulative. However, internal use is not advised.
In Iceland, the plant was introduced in the first half of the 20th century to combat erosion, speed up land reclamation and help with reforestation. The Nootka lupine has shown itself to be a very effective plant for land reclamation in Iceland. Dense plant cover and soil fertility can be gained within a relatively short time span, where the growth of the lupine is not limited by droughts.The lupine is well suited for reclamation of large, barren areas because of its nitrogen fixation and rapid growth. Furthermore it has an ability to extract phosphorus from compounds in poor soils. In some places, however, this is by many people thought to have caused problems because of the lupine spreading too quickly. Since other plants find it difficult to root in the loose, eroded soil where it is generally planted, the lupine can grow unhindered and creates monocultures which is believed to prevent native flora from flourishing. On the other hand the species can make fertile soil in deserted areas gaining ground for a plant colonisation process enhancing a richer ecosystem with greater biodiversity.
Naturally the lupine retreats gradually along with increased fertility of the soil and gives way for other species. This is evident on sites in Iceland where the lupine was introduced early, such as in HeiÃ°mÃ¶rk near ReykjavÃk.In its native habitat in Alaska, the Aleutian Islands and British Columbia the Nootka lupine is most common on eroded sites such as river banks, along roads etc. In the end this will most probably be the case in Iceland as well but how long this will take is uncertain and subject to varied factors.

Beautiful and remarkable image, very well done on the notes, thank you for letting us know a bit of your experiences and our nature world, glad to have met you here.
very nice picture with good details
the blue colours are super good
thanks gr lou
You captured this flower well. Good details and DOF. I like its natural habitat which you wanted to show. Just don't like upper portion horizontal different light shade; if you could get rid of this light and angle, I think this picture would have been more appealing.
Thanks for sharing,

A very pretty lupine with beautiful petals that appear to be multi colored. Nicely framed while showing wonderful detail and plenty of DOF. Exposure is great considering the bright lighting you had to deal with.
I have only seen lupine growing wild one time which was in the state of Maine, what a sight. TFS.

Lovely pic showing this beautiful bouquet of lilac flowers.
Thanks for sharing!
Ciao Luciano, bella pianta, ottimi colori naturali, a _Ventotene ci volavano meno farfalle che in Islanda, fortuna Gavelli, buon week end, ciao Silvio
But Iceland is colorful. Beautiful specimen lupine.
Le sujet est bien cadrÃ©. La prise de vue permet de voir les dÃ©tails du Lupinus nootkatensis. La bonne luminositÃ© fait ressortir la beautÃ© des couleurs. Bonne soirÃ©e.
Hello Luciano â Very good picture of this Lupinus nootkatensis from Islande. Excellent, view showing us all the details of the flowers and leaflets. Colours from the flower properly caught.
â¢ Excellent focus on the flowers and in the same times on the whole inflorescence and leaflets
â¢ Perfect exposure with an appropriate choice of aperture/speed and iso.
â¢ Perfect depth of field and sharpness â In my opinion, a âfrom belowâ view will have be a better choice a good choice (you will magnify the inflorescence and, in the same times, make the confuse background to disappear)
â¢ Good contrast
â¢ Excellent sharpness showing all the details of the flowers
â¢ Precise white balance and exact colour rendering for the butterfly and the flowers
â¢ Good post processing without any excess
â¢ Good background blur, but background âtoo presentâ, notably disturbing the view on the flowers.
â¢ Interesting picture showing in one time the individual flowers, their inter-relations and the leaflets; good capture.
â¢ Efficient framing and composition with an appropriate disposition of the subject inside the frame. Personally I will have done a picture in a âfrom belowâ design, in order to magnify the flowers and the size of the inflorescence. Thank you for the sharing.
Have a good day.
