THE BOOK OF GARDENING. 



T. p. liliacea, clear rose ; and T. p. immaculata alba, pure white 

 are real gems. There is also a species of recent introduction in 

 T. Pringlei. It is a Mexican plant of great beauty, the flowers 

 being large and of a glossy scarlet. Still more recent is T. Van 

 Houttei, with small bronze-black flowers. A bed of Tigridias in 

 blossom is a sight not likely to be forgotten. 



Trillium (Wood Lily). — North American plants of distinct 

 appearance, and valuable subjects for moist, shady nooks in the 

 ordinary garden or for similar positions on rockeries. They 

 flower in spring, and should be freely planted, especially T. grandi- 

 florum, snowy-white, set amidst pretty foliage. Another very 

 desirable sort is T. sessile californicum, creamy-white, with spotted 



foliage; while T. recur- 

 vatum, purple, marbled 

 foliage, and T. stylosum, 

 rose-pink, are very pretty. 

 Trilliums should be 

 planted in autumn and 

 not be often disturbed; 

 propagated by division. 

 The petals, calyces, and 

 leaves being arranged in 

 threes have also earned 

 for this genus the popular 

 name of Trinity Flower. 



Tritonia (including 

 Montbretia). — In this 

 genus are found some 

 graceful and showy plants 

 flowering in summer. 

 Those ■ usually catalogued 

 as Montbretias are the 

 most popular. The foliage 

 partakes of that of the 

 Gladiolus, and the blos- 

 soms are some shade of orange, and valuable for cutting. The 

 Montbretia section of the genus are best planted in autumn, lifted 

 annually, and replanted at once in fresh soil, discarding the old 

 and exhausted roots. This is by no means necessary, as excellent 

 results are frequently obtained by leaving the bulbs undisturbed 

 for two or three years. T. Pottsii and the variety grandifiora 

 are very decorative; but the best kinds are the garden forms 

 of T. crocosmiflora (Fig. 232) (itself of garden origin, being a 

 cross between T. Pottsii and Crocosmia aurea), which are far 

 and away superior to the type. Varieties to be recommended: 

 Bouquet Parfait, Pluie d'Or, Etoile de Feu, Rayon dOr, 

 Transcendant, Tigridie, Sulphurea, and Eldorado.
