30/ Jamaican cherry 

Consistently fruits from spring to fall, and sometimes in winter if it gets enough light. It needs to be brought in when temperatures get below 40F at night. It is a water hog and it does need fertilizer if you want to have a lot of fruit. Provided fertilizer, it is a heavy fruiter and is popular with the pollinators. Does not do well in high winds, needs a sheltered location with a lot of sun.
