TRITELEIA TR1TONIATROP&OL UM TUBEROSE 307 



As a pot plant for the Alpine house it is first-rate. In the open, plant 

 in October two inches deep. 



TRITONIA 



TRITONIAS are more showy than the Ixia or Sparaxis, but belong to 

 the same group of South African Irids, and require the same treat- 

 ment. They may be planted out in April, if prepared for that mode 

 of cultivation by potting them in small pots in November or December. 

 It is not considered advisable to tie them to sticks, for they are more 

 elegant when allowed to fall over the edge of the pots, and suggest 

 the 'negligence of Nature.' 



TROP^EOLUM 



Troptzolum tuberosum 



A FEW of the tuberous -rooted Tropaeolums are hardy, but it is not 

 advisable to leave them in the ground, for damp may destroy them 

 if they are proof against frost. They are all graceful trailing plants, 

 adapted for covering wire trellises, and may be flowered at any sea- 

 son if required, though their natural season is the summer. The 

 compost in which they thrive best is a light rich loam, containing a 

 large proportion of sand. The stems are usually trained on wires, but 

 they may be allowed to fall down from a pot or basket with excellent 

 effect, to form a most attractive tracery of leafage dotted with dazzling 

 flowers. The sunniest part of the greenhouse should be devoted to 

 the Tropaeolums, and special care should be taken in potting them 

 to secure ample drainage. 



TUBEROSE 



Polianthes tuberosa 



THIS bulb is extensively grown in the South of France for the deli- 

 cious perfume obtainable from its numerous pure white flowers. In this 

 country it is widely known, but considering the beauty and exceeding 

 fragrance of the blossoms it is astonishing that a greater number is 

 not planted every season. Perhaps the fact that the bulbs are valueless 

 after the first year may in a measure account for the comparatively
