These pictures are of the passion flowers in my garden. I did a little research on them and this is what I found.
Passion flowers (Passiflora spp.) grow wild in the southern parts of the United States and in most countries of South America. There are estimated to be around 400 different species of the passion flower. It's name comes from when missionaries when to south america and found this flower to be a picture of the passion of Christ, hence the name.
This particular variety of the passion flower produces a tart yellow fruit called maracuyá, or in English simply put as passion fruit. It is used to make juices here in Ecuador and all over South America.
