LIST OF FLOWERS 



petalled flowers of pure white, and though a free-growing plant its 

 beautiful foliage of soft green requires a moist and shady position. 



TRITELEIA-UNIFLORA. A charming spring-flowering bulb, 

 producing in April a profusion of violet-tinted white flowers which 

 open only in bright sunshiny days and close in dull weather. It 

 will thrive in almost any soil, though preferring a light one, and is 

 well adapted for culture in pots or in the Rock Garden. The bulbs 

 should be planted in autumn about 2 inches deep, 



TRITOMA. See Kniphofia. 



TRITONIA. See Montbretia. 



TROLLIUS {Globe-flower). A handsome, early-flowering per- 

 ennial whose deep roots delight in a rich, moist soil. T. europcsus, 

 known as the Mountain Globe-flower, and under several other names, 

 is a fine variety with many forms, of which albus, with flowers of 

 creamy-white, and superbus, with large flowers of pale yellow, are 

 excellent. T. asiacticus, the Orange Globe-flower, is particularly 

 hardy, and has also several forms, with flowers of deep orange colour, 

 but less globular in form than those of T. europceus. 



TROPiEOLUM (Nasturtium). Perhaps the most important 

 and certainly the most generally-cultivated strain is the Tom Thumb 

 or dwarf Nasturtium, a hardy annual which will thrive in any soil 

 —in a poor soil it makes less leaf and blooms more freely — ^which 

 flowers longer and more continuously, and produces a greater variety 

 of rich colouring, superb when seen in masses, than almost any other 

 aimual, whUe all the attention the plants need throughout the 

 summer is the removal of the faded flowers so as to prevent'the forma- 

 tion of seed-pods. Among the climbers T. speciosum, the Flame 

 Nasturtium, with its graceful growth and brilliant vermilion flowers, 

 stands pre-eminent; but though grown freely in the north it is seldom 

 seen in our southern counties. Though quite a hardy perennial, 

 it cannot endure hot sun and dry air, but if planted in a northern 

 aspect, or, better still, in a western aspect, and shaded by trees or 

 bushes, it will thrive and bloom freely— a suitable position, rather 

 than any particular soil, is its chief requirement. The choice of a 

 suitable position is important, too, for the display of its full beauty; 

 none can be better than to allow it to trail down the sides of a rough 

 bank or up the uneven face of a stone wall. T. Lobbianum is another 

 fine climber — an annual — ^with hairy foliage and flowers in various 

 shades of scarlet, orange and yellow; whUe T. majus is a similar
