I have a male and female tree. They are volunteers. Volunteers always seem to do better than the plants I buy.
The fruit on this tree are large, tasty and multitudinous (largest 2-3kg). It keeps me and several friends amply supplied. I work at keeping it upright so the weight of the fruit does not snap the top off (which was the fate of its predecessor).
My major difficulty with it is the shading out of my daylilies: some of which I have had to move. I keep younger volunteers going ready to replace the fruiting tree for when it is lost.
