in summer, dull yellow, in racemose 

 panicles. Useful for rockwork. 



Gulture dc. as above. Increased by 

 cuttings or division. 



A. lanata. — A very dwarf and pretty 

 rook plant, native of S. Europe, with 

 silvery grey leaves finely cut lilte the teeth 

 of a comb. The vai'iety muielKna is 

 similar, but the leaves are more loosely 

 divided.

 cuttings or division. 



A. maritima. — A British bush 10-18 in. 

 or more high, with white woolly leaves, 

 twice pinnately out into blunt linear seg- 

 ments. Flowers in August and September, 

 yellowish, erect or drooping, cottony, 

 crowded on short erect panicled spikes. 



Culture dc. as above. Increased by 

 cuttings or division. 



A. stelleriana. — A silky white vigorous 

 Siberian species 1-2 ft. high. Lower 



Tribe VIII. SENECiONOiDEiE. — Leaves alternate, rarely opposite, 

 yellow, rarely blue. Aohenes various. Pappus bristly. 



leaves spoon-shaped incised ; upper ones 

 bluntly lobed, about 2 in. long, all silvery- 

 white. Flowers in summer, yellow.

A. tanacetifolia. — A pretty Siberian 

 perennial 12-18 in. high with rather 

 downy Fem-like leaves, twice pinnately 

 out into somewhat linear lance-shaped 

 pointed lobes. Flowers in summer, 

 brownish, in simple terminal racemes. 



Culture dc. as above. Increased by 

 cuttings or division. 



A. vulgaris (Mugwort). — A British 

 plant 3-4 ft. high with furrowed stems and 

 whitish downy leaves twice pinnately cut. 

 Flowers in August, yellow. There is a 

 pleasing variegated variety and also one 

 with golden leaves. 



Culture dc. as above. Increased by

Disc florets 



TUSSILAGO (Coltsfoot). — The 

 only species belonging to this genus is a 

 British herb T. Farfa/ra, which has 

 large broadly heart-shaped, angled, 

 lobed or toothed cobwebby leaves, and 

 heads of bright yellow flowers. The 

 variegated variety is useful for growing 

 in damp shady places, but it quickly over- 

 runs the ground by means of its creeping 

 roots. It must therefore be checked from 

 getting among choicer plants. 



PETASITES. — A genus containing 

 about a dozen species of rather white 

 downy or woolly herbs with perennial 

 rhizomes or stems, and often large, heart- 

 shaped or reniform leaves. Flower- 

 heads purple or white, in racemes or 

 clustered panicles at the top" of the scapes. 

 Involucre bell-shaped or cylindrical. 

 Eeoeptacle flat, naked. 



P. fragrans (Nardosmia fragrans ; 

 Tussilagofragrans). — Winter Heliotrope. 

 A native of S.W. Europe and naturalised 

 in parts of Britain. It is about 6-12 in. 

 high, with roundish, toothed leaves, lobed 

 at the base. Flowers in January and 

 February, white or pale lilac, fragrant; 

 scales of the involucre acute. 



Other species of Petasites sometimes 

 cultivated are P. niveus, the young 

 leaves of which are silvery-white beneath, 

 and the flowers, white or pale rose, are 



produced in March or April ; and P. offici- 

 nalis, the well-known Butter-bur of our 

 wet meadows and pastures. It produces 

 its rosy flowers from March to May, and 

 thus succeeds those of the other species. 



Culture and Propagation. — These 

 plants being of vigorous and rather coarse 

 growth are best for rough banks or wUd 

 parts, in ordinary soil. Their charm con- 

 sists in blooming in the depth of winter 

 and early spring. They may be increased 

 by division after flowering. 



ARNICA. — A genus of about 10 

 species of perennial herbs with clustered 

 opposite, entire or toothed leaves, and 

 yellow flowers on long stalks. Involucre 

 more or less bell-shaped. Eeceptacle 

 flat, naked, or often hairy. Achenes 

 rather hairy. 



Culture and Propagation. — Arnicas 

 thrive in a mixture of loam, peat, and 

 sand. They may be increased by 

 dividing the roots in spring. Or seeds 

 if they can be procured may be sown in a 

 cold frame at the same period, afterwards 

 transplanting the seedlings in May. 



A. Chamissonis. — A pretty N. Ameri- 

 can species 1-2 ft. high, with oblong 

 lance-shaped, pointed, or acute, woolly 

 leaves. Flowers from July to September, 

 1^-2 inches across, yellow, corymbose. 



Culture dc. as above.
