Pawpaws are native to this area as well of most of the eastern U.S. I planted 7 trees and two began producing pawpaws after three years growth. It's surprising...it's hard to see the fruit. It is close to the stem and usually hidden by the large leaves. As to taste...if you've ever had a cherimoya it's a lot like the taste of pawpaws. They look like they're in the same family although cherimoyas are tropical. I like them...not as much as cherimoyas but then I don't live in the tropics...lol. I have mine planted as understory trees. They get direct sun but not all day.

That looks awful... hope someone can help as I have babacco papaya tree too.. is paw paw the same as a babacco papaya? Meixue

My pawpaws didn't start blooming til 4 years (and that was the grafted ones) the seedling ones haven't bloomed and this is their 5th year. There is a way to look at the twigs (after leaf fall) and see if buds are there for next spring. Look for round buds (the pointed ones will only produce leaves). ~Chills

g'day garry, not sure i can help much? but yes i would have expected flowers on at least the 2 meter one by now even the other should show signs. from a seed i have had them flower in around 6 months. what variety are they the red or yellow? if yellow it might be that they are male trees they can take longer to flower some do fruit well others not so well, male fruiting not so prolific as female fruiting but just as tasty. also look at growing conditions maybe? they will like a good watering but will also like to be well drained, they also thrive in full sun, keep them heavily mulched green hay type mulches will add nutrients as they break down. len Here is a link that might be useful: len's garden page
