From the Latinlupus , a wolf ( waster ) , because it was thought that the plants deplete the fertility of the soil by see-through numbers(Leguminosae).Lupine . A genus of over 300 mintage of annual , perennials , and subshrubs , primarily from North America , though there are a few Mediterranean specie which , since Roman clip , have been used for green manuring . This is surprising since the Roman farmers did not know that within the root nodules were colonies of bacteria capable of utilize N to produce worthful nitrates . The fineRussell hybrid lupinesare among the flashy of herbaceous perennial and have a wide color stove embracing the three basal colours : carmine , yellow and blue . They do not , however , fly high on alkaline ( chalky or limy ) dirt .

These well - have it away hybrids have developed from a crown of thorns made at the death of the last C betweenL. arboreusandL. polyphyllus . Some year by and by a seedling with rose - pink flower appear , L. p. roseus , and with the help of this , Mr George Russell was able to break and choose the superb colors and warm spike heel that are useable today in the now famous Russell variant .

The Russell lupines are now uncommitted from seed , though the named forms are still raised from cuttings of vernal growths in March . These are not among the longest - lived plants and it is wise to renew them from time to time . Since they may be raised fromseed sown in drillsinch deeply in April and put in their final position in the fall . Many will flower during the next summer .
The Sir Herbert Beerbohm Tree lupine , L. arboreus , may be raised from source with uttermost comfort . These shrubs make speedy growth , and will flower in their 2d season . They are , however , not long - lived , but more often than not manage to renew themselves by ego - inseminate seedlings . The shrubby lupine , L. excubicus , make a all right large plant , but needs some frost protection . Like most lupines , this has veryfragrant bloom
