COLD GREENHOUSE, 123 



ing red and green flowers in June, and growing a foot or 

 so high, that makes an interesting subject for cold green- 

 house culture. 



The bulbs should be planted in September in a compost 

 of two parts sandy loam, one part leaf -mould, and a liberal 

 amount of coarse silver sand. Plant five bulbs two 

 inches deep in a 5in. pot; place the pots in a cold frame, 

 and cover with fibre refuse till growth begins ; then trans- 

 fer to the greenhouse. No water must be given till growth 

 begins ; afterwards give a moderate supply till the plants 

 have flowered, then gradually withhold it, keeping the soil 

 dry during the winter. The pots may be stored in a sunny 

 cold frame after flowering. Repot annually. Increased 

 by offsets. 



Bulbocodium. The only species, B. vernum, bears 

 rosy-purple flowers in February, and grows three to six 

 inches high. A pretty and interesting plant for the cold 

 greenhouse. 



The bulbs do best in shallow pans, 4in. to Gin. deep and 

 Sin. in diameter. Plant eight to twelve bulbs an inch 

 deep in a compost of two parts sandy loam, one part leaf- 

 mould, and one part of silver sand, any time in Septem- 

 ber, then store in a cold frame till growth begins. Supply 

 water freely during the growing season, and keep dry- 

 when at rest. Increased by offsets. 



Calochortus. The Mariposa Tulips are natives of 

 California, and noteworthy for the brilliancy of colour of 

 their flowers, which are borne in June and July. They 

 vary in height from six inches to two feet. There are a 

 large number of species and varieties, the names of which 

 will be found in the list of hardy bulbs on p. 51. Any 

 or all of those described there may be grown in pots or 

 pans in the cold greenhouse. 



Five-inch pots, or pans 6in. deep and in. to 12in. in 

 diameter, may be used to grow Calochorti. The compost
