ALPINE FLOWERS FOR GARDENS 



[PART II. 



6 inches high, bearing a whorl of 

 leaves, from the centre of which arise 

 from one to four slender flower-stems, 

 each supporting a star-shaped white 

 or pink-tipped flower. A native of 

 Northern and Arctic Asia, America 

 and Europe, and found in the Scotch 

 Highlands and North of England. 

 With healthy well-rooted plants to 

 begin with, it is not difficult to 

 establish among bog shrubs in some 

 half- shady part of the rock-garden, or 

 in the shade of Rhododendrons, in 

 peat soil. It is best for association 

 with Linncea, the Pyrolas, and 

 Pinguiculas, among mossy rocks. 

 Flowers in early summer, and is 

 increased by division of the creeping 

 root-stocks. 



TRIFOLIUM t (Clover}. Notwith- 

 standing the immense number of 

 kinds, there are but few, excepting 

 the alpine Trifolium, that are of 

 consequence for the rock-garden ; and 

 there are so many pretty plants from 

 the same Pea-flower order that we are 

 never short of a like kind of beauty. 

 The alpine Clover is a rather showy 

 plant of easy culture. 



TRILLIUM (Water Robin). 

 Singularly formed North American 

 perennial plants of value and interest 

 for the moist parts of the rock-garden, 

 and also for the marsh-garden, thriving 

 best in rich and moist sandy soil or 

 peat, or, if in loam, with added leaf 

 soil. They are natives of moist woods 

 and thickets, and, therefore, if we wish 

 to see them at their best, partial shade 

 is a help, but they should not be 

 robbed by hungry shrubbery roots. 



Trillium grandiflorum (White Wood 

 Lily). One of the mostsingularand beauti- 



lovely, white, three-petalled flower, fairer 

 than the white Lily, and almost as large 

 when the plant is strong. It thrives in 

 a free deep soil, full of vegetable matter, 

 and a shady position. If placed in a 

 sunny or exposed position, the large soft 

 green leaves will not develop. At 

 Biddulph Grange I saw it forming bushes 

 of the healthiest green, more than 2 feet 

 high, and spreading out as freely as any 

 border-plant. It was planted in a moist 

 spot, shaded and sheltered by high banks 

 and shrubs. In such positions it may be 

 grown as well as in its native woods. 



Trillium erectum is a curious species, 

 with broad leaves 2 to 6 inches wide, and 

 brown-purple or white flowers. It is also 

 found in East Siberia, and is nearly 

 allied to the plant found in Japan, if not 

 identical with it. It is figured in 

 Salisbury's "Paradisus," t. 35, as T. 

 fatidum. Flowers in May and June, and 

 is found from Canada to North Carolina. 



T. erythrocarpum is a shy flowerer, and 

 not easy to keep in health. It is called 

 the Painted Lady, and surpasses all the 

 others in the beauty of its flowers, which 

 are white, with bright purple streaks. 

 The flowers are, however, small, appearing 

 in May and June. Georgia, on high 

 mountains, or in cold damp woods. 



T. pusillum, recurvatum, stylosum, 

 nivale, ovatum, petiolatum, and undu- 

 latum are rare in gardens, and more 

 worth growing. T. sessile, with brown 

 flowers and mottled leaves, is best known 

 through the variety Californicum, which 

 has large rose-coloured or white flowers, 

 and is a useful, easily grown plant. 



TROLLIUS (Globe Floiver).Stont 

 and handsome perennials, inhabiting 

 alpine and northern pastures. 



Although plants of the semi-marshy 

 sub-alpine pastures and copses, they 

 will thrive in exposure if kept moist at 

 the roots, that is to say, planted in a 

 deep, rich soil, as then the roots are less 

 affected by drought. The best time to 

 propagate the Globe-flower is in 

 September, when the roots may be lifted 

 and divided to almost any extent. If
