PRACTICAL GUIDE TO GABDEN PLANTS potbntilla 



Spain, where it grows in the clefts of the 

 rocks at an elevation of about 10,000 ft. 

 The leaves are composed of 5 leaflets 

 clothed with a short, soft, silvery down, 

 and the pale yellow flowers appear in 

 May and June. 



Culture dc. as above, p. 376. 



P. nitida. — A native of S. Europe form- 

 ing broad silvery cushions or carpets 

 scarcely 2 in. high. The leaves are com- 

 posed of 3-5 shining, silvery, obovate or 

 wedge-shaped leaflets. Flowers in sum- 

 mer, soft delicate rose, but of a much 

 deeper tint in the variety atrorubens. 



Culture d-c, as above. Although this 

 species is easily increased by dividing the 

 tufts, it seems as if plants raised from 

 seed are hardier, and better in every way. 

 This species is remarkable for having pink 

 flowers, the majority of the other species 

 being yellow or white. There is, however, 

 a white-flowered form of nitida proper. 



P. nivea. — A dwarf tufted species 

 about 2 in. high, native of the mountainous 

 regions of Europe, Asia, and N. America. 

 The whitish downy leaves are composed 

 of 3 spreading leaflets, the under surface 

 of which is snowy-white. Flowers yellow, 

 from May to July. 



Culture dc. as above. This species 

 likes gritty peat and loam in half-shade^ 

 parts of the rockery. 



P. opaca, — A native of the mountains 

 of Central and N. Europe, N. Asia, and 

 N. America. The branches trail on the 

 surface of the soil, and are furnished with 

 large leaves composed of 5-7 leaflets 

 covered with soft hairs. The yellow 

 flowers appear in May and June, ap- 

 parently on the surface of the groimd, on 

 account of the trailing stems. 



Culture Sc. as above, p. 376. 



P. pyrenaica. — A showy Pyrenean 

 species 6-18 in. high, sometimes covered 

 with adpressed hairs, sometimes nearly 

 smooth. Leaves 3-5-lobed, velvety or 

 rather smooth, the lower ones on long 

 stalks. Flowers in summer, deep golden- 

 yellow ; petals very romid, and over- 

 lapping. 



Culture Ac. as above, p. 376. 



P. recta. — A rather stif&sh erect- 

 grovnng species 12-18 in. high, native of 

 the European mountains, with leaves 

 composed of 5 -toothed leaflets, and bear- 

 ing numerous large primrose - yellow 



flowers from May to September. There 

 are several varieties of this fine species, 

 the best known being laciniata, macran- 

 tha, and. pahnata. 



Culture da. as above, p. 376. 



P. rupestris. — A native of the moun- 

 tains of Central and S. Europe, with erect 

 brownish stems 1-^-2 ft. high, and pinnate 

 leaves made up of 5-7 oblong toothed 

 leaflets. The white flowers are borne in 

 a loose panicle throughout the summer 

 months. 



Culture dc. as above, p. 376. 



P. russelliana. — 'This is supposed to 

 be a hybrid between P. argyrophylla 

 atrosanguinea and P. nepalensis. In 

 summer and autumn it bears its rich 

 blood-scarlet flowers, nearly 2 in. across. 



Culture dc. as above, p. 376. 



P. Saxifraga. — A native of S. Europe 

 4-6 in. high. Leaves with 3-5 toothed 

 or untoothed leaflets. Flowers in May 

 and June, white, in corymbose heads. 



Culture dc. as above, p. 376. 



P. splendens. — A Pyrenean species 

 with a short and rather woody branching 

 rootstock, and slender stems forming a 

 dense carpet scarcely 2 in. high. The 

 3-5 leaflets composing the leaves are of 

 a glistening green above, with a silvery- 

 white down beneath ; and the beautiful 

 white flowers appear singly on long stalks 

 from May to July. Other white-flowered 

 PotentiUas are P. Fragariadtrum, P. 

 petiolulata, P. micravtha, and P. l^yg- 

 mcea. 



Culture dc. as above, p. 376. 



P. subacaulis. — A dwarf tufted species, 

 native of the mountains of Europe, with 

 branches spreading on the surface of the 

 soil, and having leaves composed of 3 

 greyish downy leaflets. The yeUow 

 flowers appear from May to July, slightly 

 above the trailing branches. Closely 

 related to P. cinerea and perhaps only a 

 form of it. 



Culture dc. as above, p. 376. 



P. unguiculata (Ivesia unguiculaia). 

 A pretty Californian perennial 9-12 in. 

 high. Lower leaves 4-8 in. long, narrow- 

 linear, with 3 closely packed leaflets 

 clothed with silky white hairs. Flowers in 

 July, pearly -white, i in. across, in slender, 

 branched panicles.
