Thanks for the comments - I bought them under the label of being - both male/female plants !!!! At least I am getting fruit on one of them - cheers.

Looks like yours are a mix of female and hermaphrodite trees.

Interesting fruit but definitely not what we call Pawpaw in the US. Is this Papaya?

Yes Bill999, also known as Papaya here in Australia too.

I have never seen a papaya with those long flower stalks,but the funny thing is the fruits are where all the papaya I have seen are.

It's normal for Pawpaws to have long flower stems like that. But in all the many years I've grown them I've never had a hermophrodite plant yet, so it looks strange to me to see what typically looks like a male plant with fruit.

the bottom pic, with the flowers is a male. Sometimes males can actually produce fruit. it often has to do with temperature and water.

Papaya can change sex. Some growers will drive a nail (or otherwise injure the tree) to try and change it to a female, or bi-sex plant.

Most seeds sold today are bi-sex.

it is much easier on growers, who plant 100+ trees, to put 1 or 2 seeds in a hole, and know it will be a bi-sex, or female....

just 1 male or bi-sex tree, can pollinate dozens or hundereds of females. so having as many female and bisex trees as possible is optimum, and bi-sex is best.

seeds from a bisex fruit, will produce mostly bi-sex plants.

. Seeds from a

hermaphrodite plant will produce seedlings in the ratio

of one female to two hermaphrodites.

Pollination studies have shown that: 1) pistillate flowers pollinated by staminate flowers give equal numbers of male and female progeny; 2) pistillate flowers pollinated by pollen from bisexual flowers give an equal number of female and bisexual progeny, 3) bisexual flowers either self or crossed-pollinated with other bisexuals give a ratio of one female to 2 bisexual, 4) bisexual flowers pollinated by staminate ones produce equal numbers of female, male and bisexual progeny. It is evident that the second and third combinations will produce the maximum number of fruit-bearing plants (Malo, 2001).

At least 15 different flower forms have been named (e.g. Pentandria--5 stamens and a functional ovary) and, because they are correlated with different fruit characteristics, some forms, have been selected by breeders. Environmental factors may also influence sexual expression, and the sexuality of a plant may change seasonally or over the course of its lifetime. Thus the sexuality of any one plant in cultivation depends on a complex mix of genetic, developmental, and environmental factors (University of Cornell, 2000)
