144 BULBS AND THEIR CULTIVATION. 



some bulbous-rooted plants, with richly- coloured flowers. 

 All the species and varieties named in the list of hardy 

 bulbs are suitable for pot culture. They flower in July, 

 and are natives of Mexico. 



Plant three bulbs in a 5in. pot early in April. Two 

 parts loam, one part peat, and one part of coarse silver 

 sand will be a suitable compost. Place in a cold frame 

 under fibre refuse till growth begins, after which remove 

 to the greenhouse. Water freely until the foliage fades; 

 then cease the supply, remove the bulbs from the soil, and 

 place them in a dry, frost-proof place till April, when 

 repot or plant outdoors. Increased by offsets. 



Tritonia. South African bulbous-rooted plants, for- 

 merly known as Montbretias. Although usually grown 

 outdoors, yet their showy character and their compara- 

 tively easy culture render them by no means uninterest- 

 ing plants to grow in pots in a cold house, to flower in 

 early summer. T. crocata, orange; crocosmise flora, orange- 

 scarlet; and Pottsii, vermilion-scarlet, are suited for pot 

 culture. 



They should be grown in a compost of two parts sandy 

 loam, one part of well-decayed manure, and one part of 

 coarse silver sand. Five bulbs may be grown in a 5in. 

 pot. Plant the bulbs an inch deep, and then treat as 

 advised for Ixias. Repot annually, always choosing the 

 largest corms, and then good results will be ensured. 

 Increased by offsets. 



Tulipa. All the species named in the list of hardy 

 bulbs, and scores of varieties named in trade lists, may 

 be easily grown in a cold house. If early supplies of 

 flowers are desired, the early -flowering Due Van Thol type 

 may be easily forced in the warm house. Those who have 

 cold greenhouses and little garden space may certainly 

 grow any or all of those named in the list of hardy bulbs 

 published elsewhere, or any of the single or double varieties
