PASSIFLORA 



The true granadilla (P. quadrangularis) is a strong 

 rapid-growing climber, frequently planted for orna- 

 ment in tropical regions and allowed to cover arbors 

 and pergolas. Its brownish yellow ovoid fruits are 

 sometimes 8 inches in length, and within the thin 

 brittle pericarp is a large number of small flattened 

 seeds surrounded by gelatinous pulp and subacid juice. 

 When green, they are sometimes boiled and used as a 

 vegetable; when ripe, the acidulous pulp is refreshing, 

 and is used to prepare cooling drinks, or is eaten with a 

 spoon directly from the fruit. 



The passion-fruit (P. edulis) is considerably smaller 

 than the granadilla, rarely larger than a hen's egg, and 

 dull purple when ripe. Its pulp is slightly more acid 

 than that of the granadilla, but of very pleasant flavor, 

 and highly esteemed in Queensland and New South 

 Wales, where the plant is cultivated commercially. It 

 is used for flavoring sherbets, for confectionery, for 

 icing cakes, for "trifles," a dish composed of sponge 

 cake, fruits, cream, and white of egg, for jams, and 

 for other table purposes. The pulp is also eaten directly 

 from the fruit, after adding a little sugar, or is used to 

 prepare a refreshing drink, by beating it up in a glass of 

 ice-water and adding a pinch of bicarbonate of soda. 

 The plants are grown on trellises about 6 feet high; at 

 the top of the trellis is nailed a crosspiece 18 inches long, 

 from the ends of which are run two wires, the long 

 branches being allowed to hang down over these to the 

 ground. The rows are placed 15 feet apart, with the 

 vines 15 feet apart in the row. The young plants must 

 be protected in regions subject to frost; they begin 

 bearing the second year, sometimes producing a few 



which have not yet come into bearing. Like P. quad- 

 rangularis, this species is often grown as an ornamental 

 plant, and makes an excellent and rapid-growing cover 

 for fences and trellises. 



The passifloras are easily propagated by seeds or 

 cuttings, the latter method being preferable in most 

 cases. Seeds should be removed from the fruit, dried 

 in a shady place, and planted in flats of light soil. They 

 do not germinate very quickly, but the young plants 

 are easily raised, and may be set out in the open 

 ground when six months to a year old. Cuttings should 

 be taken from fairly well-matured shoots, and should be 

 about 6 inches in length. They are easily rooted in 

 sand, no bottom heat being required. Cuttings of P. 

 edulis will often fruit in pots at the age of one to two 

 years, and form very interesting greenhouse plants. 

 While this species usually fruits prolificacy, P. quad- 

 rangularis sometimes requires hand-pollination when 

 grown outside its native habitat.

fruits the first season, and continue in profitable pro- 

 duction four to six years, when they must be renewed. 

 By proper pruning, two crops a year can be secured, in 

 regions not subject to frost. The most suitable soil 

 seems to be sandy loam, although other soils will grow 

 the plant successfully. Manure should be supplied 

 liberally. In Australia, the profits of passion-fruit cul- 

 ture are reported to run from $100 to $300 an acre 

 annually. Because of the short life of the vines, they 

 are often planted as a catch-crop in young orchards
