Passion fruit is a climbing plant of the Passifloraceae family. It is the size of an egg and is yellow or purple. Purple passion fruit (Passiflora edulis) is subtropical, important in some countries, while the more tropical yellow passion fruit excels in others. Both yield delicious juice. The passion fruit vine is a shallow-rooted, woody, perennial, and climbing by means of tendrils. The alternate, evergreen leaves, deeply 3-lobed when mature, are finely toothed, 3 to 8 in (7.5-20 cm) long, deep green and glossy above, paler and dull beneath, and the fruit is purple in color when mature. Commercial farming of purple passion fruit begun in Kenya in 1933 and was expanded in 1960, when the crop was also introduced into Uganda for commercial production. In both countries, the large plantations were devastated several times by easily-spread diseases and pests. The purple passion fruit (passiflora edulis) is the most commonly grown passion for commercial purposes in Kenya. It is mainly grown for fresh and juice extraction.
Passion fruit grows in warm to cool climates within altitude ranging from 1200-2000m. above sea level and minimum rainfall of 900mm per annum. The most suitable soil is medium texture (loamy), which is deep and well-drained, with PH ranging from 5.5-7.5.
