GEANADILLA. This is a name some- 

 times given to several species of the 

 Passiflora, but one only is the true 

 Granadilla, Passiflo'ra quadrangula'ris ; 

 but P. edulis also produces edible fruit, 

 and may be similarly cultivated. We 

 are aware that there are other species 

 of Passiflora, the fruits of which are eat- 

 able, such as the P. malifo'rmis, or sweet 

 calabash ; P. laurifo'lia, the laurel- 

 leaved or water lemon ; and P. incar- 

 na'ta, or the flesh-coloured, &c. 



Propagation. They are nearly all 

 readily propagated by seeds, but most 

 cultivators who grow them for table 

 purposes prefer cuttings ; and they are 



quite right; for, like most of the Cucur- 

 bitaceous group to which they approxi- 

 mate, they are apt to run much to bine 

 if raised from seed. Plants from cut- 

 tings grow more moderately, and blos- 

 som sooner. Seedlings will fruit readily 

 at two years old; but cuttings struck 

 very early in the spring, and highly 

 cultivated, will fruit the same autumn ; 

 but not produce a full crop. 



Soil. A somewhat light and gene- 

 rous soil is best. The following is an 

 excellent compost : Decomposed mel- 

 low turfy loam, two parts ; old leaf soil, 

 two parts ; heath soil, one part ; and 

 sand, one part. 



Culture in Growing period. P. quad- 

 rangular is requires a greater heat than 

 P. edulis in fact, a heat equivalent 

 to the Pine stove ; whilst P. edulis will 

 succeed well in an ordinary vinery. 

 Bottom heat is most essential, espe- 

 cially for the P. quadrangularis ; and, 

 indeed, in this, and a generous soil, 

 consists the chief secret of successful 

 culture. No place can exceed the cor- 

 ner of the bark-bed for the culture of 

 either, provided they can ramble freely 

 overhead, unshaded by vines or other 

 creepers ; for light is also essential. 

 The corner of the bark-bed must be 

 separated by bricks, pigeon-holed ; a 

 triangular space, which will hold a 

 wheelbarrow of soil, will suffice; put- 

 ting some bricks below for drainage. 

 The shoots must be carried up to within 

 a foot or so of the roof, and may then 

 be trained in any way most convenient. 

 The P. edulis will produce many 

 branches ; these must be kept thinned 

 out, after the manner of Melons ; but 

 no stopping is requisite. The P. quad- 

 rangularis does not so soon crowd itself 

 with spray; nevertheless, it will at 

 times require thinning out. Liberal 

 waterings must be given, and it must 

 be remembered that the roots will ex- 

 tend through the pigeon-holes into the 

 bark-bed, and will principally follow 

 the side of the pit walls. The most 

 important matter, however, is the arti- 

 ficial impregnation of the blossoms ; 

 for they will seldom " set" without it. 

 The following is Mr. Appleby's mode 

 of setting P. quandrangularis. The
