They take around 5 months. They can be ripe with 50% color but fully colored fruit sometimes need to hang for a few weeks. They will soften when ready. I enjoy them most when they are a bit underripe, soft in spots and slightly firm in other. At this stage, the flavors are strong and there is a mix of pineapple, passionfruit and lemon flavors, sweet and sour. When fully ripe, the fruit are sweet and the flavor mellows. They continue to ripen after dropping/picking but I feel better picking when at the desired ripeness.
