THE FLORAL WORLD AND GARDEN GUIDE. 207 



foot liig^, are of large size, and the slipper is of a delicate rose 

 colour, whilst the sepals and petals are pure white. Several speci- 

 mens of this species have been exhibited this season, and it may be 

 truly said that none of the orchids grown in a high temperature, at 

 an immense expense, presented a more beautitul appearance. These 

 should be grown in pots filled to about one-third of their 'depth 

 with large crocks, and in a mixture of three parts fibrous peat, one 

 part leaf-mould, and one part of rough sand. Orchis foliosa is of a 

 quite distinct character to the preceding, and produces spikes of 

 purple flowers about eighteen inches in height. It makes a grand 

 specimen, and is of free growth, succeeding admirably in a mixture 

 of equal parts turfy loam and fibrous peat. They all require liberal 

 supplies of water during their growing season, and the soil to be 

 kept just moist at other times. Throughout the summer, the frame 

 must be freely ventilated, and during the continuance of frosty 

 weather be kept close. 



The side-saddle plant, Sarracenia •purpurea, has a remarkably 

 interesting appearance at all times, for the leaves have the appear- 

 ance of large pitchers, and remain in a fresh state throughout the 

 year. It thrives admirably in a mixture of peat and moss, and 

 during the summer the pots should be stood in a pan of water. At 

 the Giasnevin Botanic Gardens there is a large specimen of this 

 remarkable pitcher or side-saddle plant, which has been out of doors 

 several years, aud makes good progress. It is planted in the bog, and 

 the soil with which it is surrounded was frozen quite solid several 

 times in the course of last winter, so that there is no doubt of its 

 hardiness. 



Several of the hardy primulas are more beautiful grown under 

 glass in a cold frame than when planted in an open border. There 

 are, for example, the two Japanese species — P. cortusoules and P. 

 Japonica, and their several varieties. The best varieties of the 

 former are P. c. amcena, P. c. lilacina, P. c. alba. All the varieties 

 of P. Japonica are good. These may all be grown in a good turfy 

 loam and leaf-mould, aud when in the form of large specimens are 

 extravagantly showy. The dwarf kinds, such as P. denticulata, P. 

 farinosa, P. glaucexcens, P. glutinosa, P. luteola, P. nivalis, and P. 

 viscGsa, are all beautiful, the two latter being especially good. They 

 all thrive in a light mixture of leaf-mould, loam, and sand. 



Again, some of the tuberous-rooted begonias which are most 

 attractive, producing a profusion of brightly coloured flowers, 

 thrive exceedingly well in a frame. The best, perhaps, are B. 

 BoUviensis, scarlet ; B. odopetala, white, and B. Veitchi, vermilion. 

 These all succeed most satisfactorily in good turfy loam, leaf-mould, 

 and sand. The pots should be placed, during the wiuter, where 

 the frost cannot reach the soil. In spring, the tubers will require 

 shaking out of the old soil, and potting in fresh compost. 



There are numerous other plants suitable for frames ; but I am 

 most anxious not to overburden the reader with names, and sufficient 

 have been mentioned to make a good begiimiog with. Those who 

 are desirous of having a larger collection, may iiave a more extended 

 list by expressing their wishes to that effect in the Elobal Wobld.
