This is the granadilla known as Ester, a cross between yellow and purple granadilla. 
Ester granadilla exhibits a more consistent fruiting pattern throughout the year compared to other granadillas. 
If youre a fan of both sweet and sour flavours, you should be growing granadillas in your garden. Also known as passion fruit, this plant is an easy-to-grow climber that shoots up incredibly quickly to produce delicious, tangy fruits. And while youre waiting for the fruit to arrive, you can also take a look at their fascinating alien-like flowers that provide ornamental interest too.
