feet high, and very freely produced. Of easy culture in good, deep, 

 rich soil. A rare and very handsome plant. 



Trientalis europea 



Half-shady position in peaty soil. Slender, erect stems, bearing 

 whorls of leaves and starry, white, pink-tipped flowers. Is not 

 difficult to cultivate if good, well- rooted plants are obtained. It is 

 a native plant, found growing in woody and mossy places. Increased 

 by division. Quite a good plant. 



Trifolium alpinum. Clover 



Of trailing habit, with large rosy-crimson flowers in June. A 

 handsome plant, and the only one worth cultivating out of this large 

 genus. 



Trillium (Liliaceae), Wood Lily 



Very pretty deciduous plants for a shady position. They thrive 

 in deep, rich loam and leaf-mould soil, so long as it is devoid of 

 lime. They can be propagated by careful division of the roots or 

 by seed. 



T. grandiflorum. — On stems from i to 2 feet high. The three 

 large leaves are borne surmounted by the big, lovely, white, three- 

 petalled flowers. A very beautiful plant, and of easy culture. 



T. erythrocarpu7n (" Painted Wood Lily"). — A very lovely plant. 

 The pure white flowers, like a small T. grandiflorum, have purple 

 streaks at the base of each segment. Rather difficult to grow, and 

 a shy bloomer. 



Other species worth growing are the rose-coloured form of T. 

 grandiflorum, T. sessile, T. californicum, and T. nivale. 



Trollius (Ranunculaceae), Globe Flower 



Very handsome plants for a moist position in deep, rich soil. 

 Easily propagated by division or seed. They mostly grow about 

 2 to 3 feet high, and are amongst the best and finest plants for the 

 bog garden, and are all of easy culture. 



T. acaulis.—K dwarf species, only growing some 6 to 8 inches 

 high. Golden-yellow-coloured flowers, with brown outside. Very 

 desirable for a damp spot in the rock garden. 



T. europaeus. — The common Globe Flower, which is the parent of 

 all the lovely garden varieties. It grows about 18 inches to 2 feet 

 high. Flowers pale yellow.
