Mexican Sour Gherkin (Melothria scabra) is also called mouse melon, cucamelon and has a few other common names.
It is a lovely perennial fruiting vegetable that I have not grown for a few years. I planted it in less than ideal soil, being shaded by plants that grew over it, so they did not crop nearly as well as they should have. Below are the days to maturity for this plant in my garden this year.
Days to maturity Mexican Sour Gherkin (Melothria scabra)
Planted 11/10/2016 Day 0
Germinated 03/11/2016 Day 23
Flowered 28/02/2017 Day 140
First fruit ripe 06/04/2017 Day 177
The flowers kept aborting so it could have set fruit much earlier. I assume they were aborting due to poor growing conditions, there were plenty of different types of pollinators in the garden this year. Hopefully they survive over winter and produce a lot earlier next summer.
