It is rich in nutrients and is used as a healing herb and is an ingredient in many recipes. It is an attractive vining plant and is easily grown in gardens and does well as a container plant. Gulupa can be an irritant to those who have allergies to latex and while the flesh of the fruit is highly nutritious the skin is toxic, containing cyanogenic glycosides, and combined with the enzymes present in the skin form the poison cyanide; thus the skin is not edible and the fruit must be peeled before eating or used in recipes.

Gulupa has a smooth outer skin that is thick and is dark purple in color. Its flesh is yellow and juicy containing edible seeds and it has a mildly sweet, acid flavor with a pleasant scent. The plant can be found growing in the Andes mountain range at an elevation between 8,200 and 12,467 feet.

How To Grow Gulupa

Growing gulupa is fairly easy and because it is a vine and a tropical plant it can be grown outdoors in warm climates and makes a decorative container plant for the colder climates, where it can be planted outdoors after the last frost. It can be planted from vine or seed in full sunlight and needs to be trellised for support of the vine. Use fertilizer made for flowering fruit and mulch the area to hold in the moisture. When growing gulupa in containers provide adequate size and support for the vines.

There are several types of gulupa, the purple variety of passion fruit. The Black Knight was developed in Massachusetts for potting and produces a fragrant, dark, purple-black fruit that is the size and shape of a large egg. The Edgehill originated in California and is similar to the Black Knight, only larger in size and does well outdoors. Another California variety is the Frederick, which is more oval and less purple in color and is slightly tart in flavor; it is used for juicing or can be eaten raw. The Purple Giant is, as its name implies, a very large fruit for the species.
