CHRYSANTHEMUM 



CHRYSANTHEMUM 



935. Chrysanthemum 

 lacustre. A short-rayed 

 form. (XJi) 



hybrid) is an early-flowering very floriferous race, 

 with several strains of fls., mostly large and pure 

 white, although in one form the buds are reported 

 as lemon-yellow but opening white; various sub- 

 varieties are now offered. 

 It is a good summer and au- 

 tumn bloomer, and usually 

 hardy in the northeastern 

 states. 



19. uliginosum, Pers. (Pyreth- 

 rum uliginosum, Waldst.). GIANT 

 DAISY. Stout, erect bushy leafy- 

 stemmed perennial, 4-7 ft. high, 

 with light green foliage: st. 

 nearly glabrous, etriate, branch- 

 ing above, 

 roughish: 

 Ivs. long- 

 lanceolate, 

 prominently 

 pointed, 

 with large 

 coarse sharp 

 teeth: heads 

 often sev- 

 eral together and not long- 

 stalked, 2-3 in. across, white, 

 late. Hungary. B.M.2706. A.F. 

 4:523; 8:813. Gng. 2:375; 5:

 It blooms the first year from 

 seed or division, and has been 

 forced for Easter somewhat as 

 Hydrangea paniculate can be 

 treated. Excellent for cut-fls. The blossoms should 

 be cut soon after opening, as the disks darken 

 with age. The plant needs a rich moist soil; 

 it deserves a greater popularity. 



20. Leucfinthemum, Linn. (Leucdnthemum 

 vulgare, Lam.). WHITEWEED. OX-EYE DAISY. 

 Fig. 937. Glabrous perennial erect weed, 

 1-2 ft. high: root-lvs. long-petioled, with a 

 large, oval blade and coarse, rounded notches; 

 st.-lvs. lanceolate, becoming narrower toward 

 the top, serrate, with few distant and sharper 

 teeth. (Var. pinnatifidum, Lee. & Lam., has 

 more divided Ivs.): heads terminal, showy 

 white. June, July. Eu., N. Asia. Gn. 70, p. 176. 

 One of the commonest weeds in the eastern 

 states, being characteristic of worn-out mead- 

 ows. The daisies are not cult., 



but they are often gathered for 

 decoration, and make excellent 

 cut-fls. The plant is very vari- 

 able, and forms adapted to fl.- 

 garden uses will probably be 

 developed. Rayless plants are 

 sometimes found. 



21. nippSnicum, Hort. (Leu- 

 cdnthemum nippdnicum, 

 Franch.). Differs from others 

 of this set in being shrubby at 

 base and Ivs. broadest above 

 the middle: to 2 ft., the sts. 

 strong, simple, few-fld.: Ivs. 

 thick, oblong-spatulate to ob- 

 lanceolate, sessile, irregularly 

 denticulate but entire at base, 

 3-4 in. long, pale beneath: fl.- 

 heads 2-3> in. across, with a 

 hemispherical involucre of oval 



937. Chrysanthemum Leu- 

 canthemum. Ox-eye daisy, or 

 whiteweed. ( X 1 A) 



936. Chrysanthemum maximum. ( X M) 



obtuse bracts; rays bright 

 white, linear, minutely 5- 

 toothed; disk pale greenish 

 yellow. Japan. B.M. 7660. 

 R.H. 1905, p. 47. F. E. 20: 

 434. Hardy in the N., in 

 the root, but the sts. killed 

 down by frost; has the 

 general appearance of C. 

 lacustre. A beautiful large- 

 fld. species, producing its 

 large blooms in late autumn. 

 22. arcticum, Linn. Low 

 perennial, 3-15 in., glabrous 

 or nearly so: Ivs. cuneate, 

 long - tapering at base, 

 toothed or cut at the apex, 

 sometimes 3-5-lobed, the 

 uppermost ones small and 

 very narrow and nearly en- 

 tire: involucre-bracts broad 

 and brown-margined; rays 

 clear white, about 1 in. 

 long: pappus wanting. 

 Arctic Eu., Asia and Amer. 

 An attractive very hardy 

 species, making a clump of 

 dark green foliage and pro- 

 ducing in autumn many 

 large white fls., sometimes 

 tinged lilac or rose. 



C. coronopifdlium, Willd. = C. 

 roseum. C. grdnde, Hook. f. 

 (Plagius grandiflorus, L'Her.). 

 Stout erect perennial of Algeria, 

 2-3 ft.: Ivs. oblong to linear- 

 oblong, often lyrate, coarsely toothed: fl.-heads large, solitary, ray- 

 ra-n/ou y ellow - to 2 in - across. B.M. 7886. C. grandifldrum, 

 Willd. bhrubby, smooth, from the Canaries, with cuneate lobed

 variable. C. inoddrum, Linn.=Matricaria inodora. C. macro- 

 phyllum, Waldst. & Kit, Perennial herb, 3 ft.: Ivs. very 

 large, nearly sessile, pinnatisect, the lobes lanceolate 

 and coarsely toothed: heads very many, corymbed; 

 rays white with yellowish tinge, the disk yellow. June, 

 July; an outdoor plant. Hungary. G.W. 12, p. 410. 

 C. Mdwii, Hook. f. Herbaceous, with woody root- 

 stock, 1 Yi ft. : Ivs. about 1 in. long, triangular to ob-

 rocco; summer in the open. B.M. 5997. C. muUiflb- 

 rum, Hort. Fls. greenish white: said to be a cross

 apparently not a garden species). C. ochroleiicum, 

 Masf. Glabrous undershrub of the Canaries: Ivs.

Types of the common 

 chrysanthemum. 



The common chrysanthemums 

 of the florists (C. hortorum) are 

 often called "large-flowering," 

 and "autumn chrysanthemums," 

 to distinguish them from the 

 hardy outdoor kinds, although
