Papaya plants produce flowers that are either male, female or hermaphrodite. Male plants do not produce fruit. Female plants must be pollinated by either male or hermaphrodite flowers to produce fruit. Hermaphrodites are self fruiting and the most desirable kind. The Hawaiian Solo papaya produce seedlings that are either female or hermaphrodite but no males. 30% will be female and 60% will be hermaphrodite so you are always assured that you have a plant that can produce fruit.
