GREENHOUSE AND HOTHOUSE FLOWERS 177 



greenhouse, as does primulinum, cream to yellow, a charming kind, 

 with very large flowers, and thriving as a bush in a large pot ; a 

 plant so grown in the greenhouse at Kew forms a part of one of 

 our coloured plates. Sambac, white flowered, is a hothouse species ; 

 both it and its double form are popular plants. With the exception 

 of primulinum the Jasmines are grown as climbers. They are 

 frequently planted out in a bed, and trained up a pillar. They will 

 thrive in the normal soil, but enjoy a little peat. Propagation is 

 effected by cuttings, which should consist of firm young wood with 

 a base of older wood ; they root with the greatest certainty if kept 

 close under a handlight or bell-glass. To get the finest flowers 

 some pruning should be practised, the young shoots which have 

 bloomed being cut out to make way for new wood. At the 

 same time, it is not desirable to cut the plants as severely as 

 exhibition Roses ; allowance should be made for the free, graceful 

 growth which is so desirable. 



Lapageria. The Lapageria is one of the most beautiful of roof 

 plants for intermediate and cool houses. The flowers are tubular, 

 three to four inches long, and one to two inches across at the 

 mouth. The type is rose, and there is a white variety of it. 

 They are of great substance, and the white is quite wax-like in 

 its texture. The writers once had to do with a remarkable plant 

 that covered the roof of a long glass corridor, and bore thousands 

 of lovely flowers every year. The Lapageria likes a peaty rather 

 than a loamy soil. Propagation is by layering, but it is not often 

 that many plants are wanted, as one will cover a considerable 

 area. 



Lilac. The old Lilac of the flower garden is so sweet and 

 popular a flower that it is natural to feel an interest in the new 

 hybrid forms which come out from time to time. These are 

 much larger than the old favourite, and just as sweet ; moreover, 

 they give us quite new colours. They are so bright and fragrant, 

 and so well adapted for conservatory adornment, that it seems a
