The Culture of Flowering Bulbs 



TIGRIDIA see FERRARIA,A^2 9S 



TRITELEIA UNIFLORA 



THIS little gem belongs to the spring garden, and should be the 

 companion of the Dog's-tooth Violet, the Crocus, and the Snow- 

 drop. It will grow in any soil, and will produce an abundance of 

 its violet-tinted white flowers, which, when handled, emit a faint 

 odour of garlic. 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 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 



Tropaeolum tuberosum 



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

 wise 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 

 season 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.
