Flowering and fruiting begin to happen 4-6 months after planting. In Florida you can expect to harvest fruits in October and November.

The fruits form just beneath the flower head, the part of the plant is called the calyces. They are at their juiciest after the flower has shriveled up and been swallowed by the calyces.

The fruits are so uniquely shaped. They almost look like little balls of fire to me.

The edible parts of the fruit are the pedal looking parts. You can peel them apart and in the center is a seed pod that you can save for next year.
