It is likely to be a Lupinus species. Lupinus is a genus from Fabaceae; the plants from which have palmately compound leaves. The genus comprises of some 280 species found in southern and western North America.
Beautiful plant indeed.
Thank you ..., yesterday i found this site on various species of Lupinus.
I searched for acute leaf (leaflets) Lupinus and found majority search results leading to L. polyphyllus. But, as ... said there are about 280 species of this genus and must be some hybrids too, i think, without any leaf size or other data it might not be possible to ascertain it to the species level.
