Passion fruit vines.
A favorite plant in many Australian gardens is the Passion Fruit, really a vine, passion fruit or Passiflora edulis is an excellent fruiting plant for a sunny position.
Without doubt the best known varieties grown in Australia are the famous 'Nelly Kelly' a wonderful black fruiting variety that has provided essential ingredients for Pavlovas for many years. The 'Bannana' passionfruit would be next, elongated fruit and found in many home gardens. Both of these varieties seem well suited to cooler climates.
Passion Fruit are all vigorous vines and heavy feeders, they climb using tendrils so a 'wire trellis' suits well for support. Avoid planting passionfruit where they will have competition around the root system if possible. Grown in an open sunny position or against a sunny wall or fence seems to be the favorite way in many Australian gardens.
Most new vines take 2 - 3 years to be fully productive, many growers use poultry manure as fertiliser ( the pelletised stuff is excellent) and regular watering is essential.
The best time to apply fertilizer is in spring, remember to water well first. We suggest that you do not go to heavy with the fertilizer as this can cause bud drop.
After a number of years fruiting often seems to decline, best to replace the vine at this time.
Some passionfruit vatieties are more cold tolerant than others, for example 'Sweetheart' prefers warmer climates, Jumbo Gem can take a little cooler. Tropic as the name implies needs a sub tropical to tropical climate. Misty Gem is a versatile performer, while Panama Red needs sub tropical at least. Generally the more commom black variety is better suited to cooler climates, and of course the banana passionfruit grows well in colder areas as well.
