CHRYSANTHEMUM 



DAISY OBDEB 



PYEETHEUM 535 



bluntly and somewhat pinnately cut. 

 Flowers from June to August, 2 in. 

 across, white, with yellow centres. 



Culture So, as above for C. laousire. 

 Increased by seeds or division. This 

 species is best treated as a biennial and 

 the plants should be renewed every year 

 either by seedlings or fresh offsets from 

 the old tufts. 



C. maximum. — A handsome strong- 

 growing Pyrenean plant 2-4 ft. high, with 

 broadly linear lance-shaped strongly 

 toothed leaves 3-5 in. long, the lower ones 

 stalked, the upper sessile. Flowers from 

 June to October, 2-8 , in. or more across, 

 pure white, with a yellow centre. 



Culture and Propagation. — On 

 light dry soils this species grows only 

 about 15 in. high, but flowers freely. In 

 deep moist soils in sunny positions it 

 attains its greatest height and vigour and 

 makes handsome flowering bushes. It 

 may be easily increased by dividing the 

 roots in autumn or spring ; or by cuttings 

 of the young shoots inserted in sandy soil 

 in early summer under handlights and 

 kept shaded from bright sunshine until 

 nearly rooted. Seeds may also be sown 

 in the same way as recommended above 

 for C. lacustre. 



C. multicaule. — A glaucous Algerian 

 annual 6-12 in. high, with fleshy linear 

 spoon-shaped leaves pinnately cut or 

 trisected. Flowers in July and August, 

 solitary, 1^-2^ in. across, golden-yellow. 



Culture do. as above for C. carinatum. 

 This species makes good dwarf tufts or 

 carpets and is useful for fronts of borders 

 or rockeries. May be raised from seed 

 in spring or autumn. 



C. segetum {Corn Marigold). — A 

 handsome British annual about IJ ft. 

 high", with stalked obovate, toothed and 

 lobed leaves, lower ones pinnately cut, 

 upper oblong, half stem-clasping. Flowers 

 from June to September, 2 in. across, 

 golden-yeUow. The variety grandiflorum 

 has larger flowers. 



Culttire a/nd Propagation. — Seeds of 

 the Corn Marigold should be sown 

 annually in the open border in ordinary 

 good soil either in autimin or spring. If 

 in autumn there is a better chance of 

 flowering early the following year. 



C. serotinum [Pyrethrum uligino- 

 sum). — Great Ox-Eye Daisy. — A hand- 



some N. American perennial 4-0 ft. high, 

 with stout stems and smooth lance-shaped 

 sharply toothed sessile leaves 3-4 in. long. 

 Flowers in September and October, 

 solitary, about 3 in. across, pure white 

 rays with a yeUow centre. 



Culture and Propagation. — This fine 

 species is very common in cottagers' 

 gardens, and is known popularly as the 

 Michaelmas Daisy, as it is always in 

 bloom at Michaelmas. It thrives in 

 ordinary garden soil and naturally in- 

 creases itself if left alone. The rootstocks 

 may be split up in early spring to increase 

 the stock. By pinching out the tips of 

 the shoots in May or June, dwarfer and 

 more branching plants are obtained. 



PYRETHRUM.— BotanicaUy there 

 is practically no difference in the struc- 

 ture of Pyrethrum and Chrysanthemum, 

 except that the flowers of the former have 

 a ' pappus ' in the form of a raised mem- 

 branous border, and angular, but not 

 ' winged,' achenes. Some of the plants 

 described in this work as Chrysanthe- 

 mums (e.g. C. frutescens, C. serotinum,, 

 C. lacustre) are also to be found de- 

 scribed under Pyrethrum by some 

 authors. 



Culture and Propagation. — Most of 

 the Pyrethrums are easily grown in 

 ordinary good and well-drained garden 

 soil. Those which may be grown as an- 

 nuals require the treatment as described 

 for such at p. 78, while the perennial 

 varieties may be increased by division or 

 seeds. Besides these general instructions, 

 special cultural remarks are attached to 

 each species described. 



P. achilleaefolium. — A pretty Caucasian 

 species about 2 ft. high, with finely cut 

 silky or downy leaves. Flowers in 

 summer, golden-yellow, almost globtilar, 

 few, on long stalks in loose corymbs. 

 This species is also known in gardens as 

 Achillea aurea. 



Culture dc. as above. Increased by 

 division in early spring, or seed sown in 

 cold frames when ripe, or in gentle heat 

 in spring, afterwards transplanting the 

 seedlings about May to the open border. 

 The plants should be grown in deep 

 moist soil. 



P. corymbosum. — A European species 

 about 1 ft. high, with angular stems, and 

 leaves pinnately cut into lance-shaped 

 deeply incised and sharply toothed lobes.
