LUNARIA 



LUPINUS 



much admired, since the fls. do not possess the bright 

 color of the type species which is objectionable to many 

 persons. 



rediviva, Linn. Differs from the last in being peren- 

 nial, the fls. usually larger and lighter colored (often 

 grayish purple), May and June, and the pod elliptic or 

 lance-elliptic, and tapering to either end: l%-7 ^ ft. 

 tall. Eu. Less common and less valuable than L. 

 annua. Thrives best in partial shade.

LUPINUS (from the Latin lupus, a wolf, because a 

 crop of lupines was supposed to destroy fertility). 

 Leguminosae. LUPINE. Usually herbs adapted to bord- 

 ers in masses, and to all places in which low-growing 

 showy herbs would be found; some make good bedding- 

 plants, others cut-flowers. 



Mostly annuals or herbaceous perennials, 2 species 

 in cult, being shrubby: Ivs. usually digitate, with 5-15 

 entire Ifts. : fls. with calyx deeply bilabiate, 5-toothed, 

 unequal; corolla with simple erect broadly ovate stan- 

 dard, having strongly reflexed sides; wings united at 

 the apex and inclosing the keel; stamens united into a 

 closed tube: pod 2-valved, flattened, inclosing several 

 large seeds. A group of about 300 species mostly con- 

 fined to W. N. Amer., a few growing in E. N. Amer., 

 Peru, Brazil, Mex., Guatemala, Afr., and in the Medit. 

 region. A very variable genus in the garden. There 

 are numerous garden hybrids of unknown parentage. 

 Some of these names will be found in the supplementary 

 list. Voss groups 'these under the name of L. hybridus, 

 Hort., and its vars. atrococcineus and roseus, or florists' 

 lupines. They have variegated fls. 



In addition to those described below the following 

 native species have been advertised, mostly by Gillett, 

 in 1881, for western collections. Probably they are not 

 in cultivation. They are mostly described in Bot. Calif. : 

 L. albicaulis, L. Chamissonis, L. lepidus, L. leucophyllus, 

 L. ornatus and L. villosus. 



The lupines are showy plants with conspicuous 

 flowers in terminal racemes, those of the species in cul- 

 tivation being mostly verticillate. The flowers are 

 blue, white or yellow, or a union of these, papiliona- 

 ceous and free-blooming. All are of easy cultivation in 

 any garden soil, except that they are said not to suc- 

 ceed in soil containing lime. They are propagated by 

 seed, the perennials also by division. They do not bear 

 transplanting when once established, hence it is recom- 

 mended to sow seed where the plants are finally desired. 

 A few species are of value economically for soiling or 

 plowing under.
