from enemies, and need no protection of any kind, even 

 in the severest winters. The roots are bundles of fleshy 

 tubers, and are sometimes classed with bulbs in cata- 

 logues of nurserymen. Small plants will bloom the first 

 year from the nursery. Clumps can often be left undi- 

 vided for four or five years without loss in size or num- 

 ber of flowers, but as a general thing all robust-growing 

 herbaceous perennials should be divided frequently. 

 In old clumps the roots often become firmly matted

near the middle, and the wasteful competition between 

 the too-numerous roots weakens the vitality of the 

 plant and the flowers are likely not to be good. Next 

 to H. flava, the oldest garden favorites among the yellow 

 day lillies is H. fulva, sometimes called brown day lily, 

 and erroneously in some catalogues the lemon lily. H. 

 fulva is a taller plant, with later and orange-colored 

 flowers and wavy inner segments. H. aurantiaca has 

 come into prominence, and its var. major by some con- 

 noisseurs is considered the finest of all day lilies. As a 

 rule, double forms are not so popular as the types, and 

 they lack the simplicity and definite character of the 

 single flowers. Yellow day lilies have a wholesome 

 fragrance. The individual flowers are short-lived, but 

 there is a good succession. The plants thrive in almost 

 any garden soil, but are most luxuriant along the bor- 

 ders of ponds or moist places, and in partial shade. The 

 flowers are excellent for cutting. Plants propagated by 

 division. R. B. Whyte gives the succession of bloom at 

 Ottawa, Canada, as follows: H. Dumortierii, June 4; 

 H. minor, H. MiMendorfii and H. Thunbergii, June 11; 

 H. rutilans, June 18; H. fulva, July 2; H. aurantiaca var. 

 major, July 9; H. fulva var. Kwanso, July 23, and H. 

 disticha fl.-pl., July 30. The common species, particu- 

 larly H. fulva, often colonize about yards, and along 

 roadsides, sometimes making great areas of foliage and 

 very little bloom. There are several worthy hybrids in 

 cultivation in the choice collections of plants (see 

 supplementary list).

A. Group of yellow-fld. species: fragrant. 



1. flava, Linn. LEMON LILY. Fig. 1806. Lvs. 18-24 

 in. long, 6-8 lines wide: scapes longer than the Ivs.; 

 corymb 6-9-fld.; pedicels 12-24 lines long; tube 6-15 

 lines long. Eu., Temp. Asia. B.M. 19. A.G. 17:437; 

 24:363. Gn. 48, p. 400. G.W. 8, p. 277. Blooms in 

 June in the N. U. S. 



2. Thunbergii, Baker. Except for its later flowering, 

 according to Baker, this species does not differ mate- 

 rially from H. flava: Ivs. 6-7 % lines wide: 

 corymb loose, 8-10-fld., with 1 or 2 fls. 

 lower down; tube nearly 1 in. long; fls. 

 lemon-yellow, opening widely, 3 in. across; 

 segms. membranous, crisped. Japan. Intro. 

 1890. Said to differ from all "others in 

 having the upper 6-10 in. of the scape 

 thickened and flattened. 



3. luteola, Hort. Hybrid of H. auran- 

 tiaca var. major x H. Thunbergii: fls. gol- 

 den-yellow, 6 in. across, on stout branch- 

 ing sts. 4 ft. high. Midway between 

 parents in habit and in size of bloom. 

 G. 25:346. Raised at Colchester Nurser- 

 ies, England. There is a var. major, Hort., 

 large. Var. pallens, Hort., is a hybrid 

 between H. citrina and H. luteola: vigor- 

 ous, many-fld. : fls. large, fragrant, canary- 

 yellow. 



4. Middendorffii, Traut. & Mey. Height 

 \-\Yz ft.: Ivs. 15-18 in. long, 8-12 lines 

 wide: scapes about as long as the Ivs.; 

 corymb 2-4-fld.; pedicels almost none; 

 tube 5-6 lines long; inner segms. 9-12 

 lines wide. Amur region. Gt. 522. R.H. 

 1897, p. 139. 



5. citrina, Baroni. Fls. lemon-yellow or 

 pale sulfur-yellow: differs from H. minor 

 in the Ivs. being twice as broad and the fls. 



much larger; from H. Dumortierii in having a longer 

 scape and Ivs. three times as long, and fls. twice the 

 size and longer-tubed. China. Tall-growing, very 

 fragrant; considered to be a fine species; excellent for 

 cutting. 



6. minor, Mill. (H. graminea, Andr., not Schlecht. H. 

 graminifolia, Schlecht.) Fls. golden-yellow: Ivs. 15-18 

 in. long, 2-3 lines wide, darker green than in the other 

 species: scapes about as long as the Ivs.; corymb 3-6- 

 fld.; pedicels 3-24 lines long; inner segms. membranous 

 and wavy at the margin. July, Aug. N. and E. 

 Asia. B.M. 873. Var. crdcea, Hort., is saffron- 

 yellow. 



AA. Group of orange-fid, species: the last not fragrant. 



7. Dumortierii, Morren (H. rutilans, Hort. H. 

 Sieboldii, Hort.). Height 1^-2 ft.: Ivs. 12-15 in. long, 

 6-8 lines wide: scapes hardly as long as the Ivs. ; corymb 

 2-3-fld.; pedicels 3-6 lines long; fls. 2-23^ in. long, while 

 they are 3-4 in. long in the other species; inner segms. 

 5-6 lines wide; tube very short. Japan. B.H. 2:43. 

 Gn. 31:280. Var. flore-pleno is less cult. This 

 species is the earliest to blossom. This species is con- 

 fused; some authors consider it to be a form of H. 

 minor. 



8. aurantiaca. Baker. Height 23^-3 ft.: Ivs. more 

 than 12 lines wide: corymb 6-8-fld.; fls. bright orange, 

 opening less widely than any other species, fragrant. 

 July. Japan or E. Siberia (?). The type was intro. to 

 cult, in 1890 and has rapidly given way to var. major, 

 Baker, intro. 1895, which is larger in all parts. Lvs. 

 12-18 lines wide: tube 9 lines long; fls. when expanded 

 5-6 in. across. July-Sept. Japan. G.C. III. 18:71. 

 Gn. 48:400; 50, p. 17. J.H. III. 31:157. A.G. 18:179. 

 Closest to H. Dumortierii, from which it is chiefly 

 distinguished by its much larger, later and more red- 

 dish fls. with longer tube.
