THE NURSERY-LIST 433 



Tricyrtis. Liliacece. 



Seeds rarely ; increased mostly by offsets and division. These 

 plants may now be known as Compsoa. 



Trifolium. Leguminosce. 



The clovers are grown from seeds sown where the plants are 

 to stand. See Clover. 



Trillium (Birthwort. Wake-Robin). Liliacece. 



Seeds sown as soon as ripe should give flowering plants in two 

 or three years. Usually multiplied by the natural increase of the 

 rhizomes. 



Triteleia: Brodicea. 

 Tritoma : Kniphofia. 



Tritonia, including Montbretia. Iridacece. 



Raised from seeds, but generally increased by division of the 

 plants. 



Trollius (Globe-Flower). Ranunculacece. 



Propagated by fresh seed, which should give blooming plants the 

 following year ; also by division of the clumps. 



Tropseolum (Nasturtium. Canary-bird Flower). Tropceolacece. 



Increased by seeds, started indoors or sown in the garden ; tuber- 

 iferous species by tubers or division of roots ; perennials sometimes 

 by cuttings under glass. 



Tsuga (Hemlock). Pinacece. 



Propagated by seeds sown in spring and by grafting on T. 

 canadensis. The varieties and Japanese species may also be raised 

 from cuttings. 



Tulipa (Tulip). Liliacece. 



Seeds may be sown in boxes of light sandy soil, in late winter, 

 and placed in a coldframe. The next season the young bulbs should 

 be planted in a prepared bed outside, and the following season 

 bloom should be had although a longer period is required before 

 maturity is reached and the full character of the flower develops. 

 Bulbels may be detached from established bulbs when they are 

 lifted, and grown by themselves ; this is the usual method. Fig. 43. 



Tunica. Caryophyllacece. 



Propagated by seeds and by division.
