Buying lilikoi fruit at a market is quite expensive, so growing your own is very satisfying and also easy to do. All you need is a seedling, a fence or trellis, water and Hawaiian sunshine! Plant the seedling (available from Gail) and train onto the fence or trellis as it grows. It will grow very fast (many people even call it 'invasive' and tear it out) so make sure you allow enough space for the lilikoi to expand; the vine will grow up to 20-30 feet the first year.
Thereafter, it will continue to grow but you can trim it back to suit your area. Fruit appears within a year or two and is harvested when it falls to the ground. The season for fruit varies (depending on location, amount of water age of the plant, etc.) but most plants in Hawaii fruit for at least 6 months, often longer.
Although there are over 500 species of Passion Flowers, not all produce fruit and not all are suitable for Hawaii's conditions. The two types of Passion Flower vines (lilikoi) typically grown in Hawaii are passiflora flavicarpa (yellow fruit) and passiflora edulis (purple fruit). Both are excellent, although many people find the purple sweeter than the yellow. Both varieties are virtually pest free (unless grown on a commercial scale) and require little attention.
When you harvest your lilikoi (or if you buy them from a market), the first step is to make juice from the fruit. See the recipe section of this website for directions on how to make juice.
