One of my Best Of Show wines is Passion Fruit! I got the fruits from a friend growing it in Ventura County, and it is so aromatic. So it got me interested in growing one of these one day, and here I am, already have fruits. It has survived our winter here. I am hoping it is aromatic.
There are ways to make your passion fruit compact and productive. It is almost the same as growing grapes in a container. Controlled girdling of the main trunk should control its roots and produce more fruits while remaining compact with a little pruning. If you remember my post about bark inversion, that is one of the techniques used for dwarfing plants with definite bark. In case it doesn't have definite bark, mild girdling is the next best thing and is a standard practice for table grape production.
This Frederick passion fruit is my first experiment on growing these, and surely I will experiment on it. But what I'd really like is the most aromatic passion fruit available in the world, and I hope you can point me to the best cultivar. I don't really care about the sweetness of the passion fruits, only the aroma, because I'm a winemaker. Passion fruits can impart the best fruity aroma to any white wines, especially if you use real fresh fruit juices applied during the final but slow fermentation phase.
