Poncirus Trifoliata fruit in July. Golf-ball size, not yet ripe.
Large-flowered form of Poncirus Trifoliata. Late February in heated greenhouse.
LEFT The total harvest October 2001 from my greenhouse plant.
The largest fruit is 5cms (2") in diameter.
BELOW The total harvest October 2001 from my outside plant. The largest fruit is 3cms in diameter.
Whether the smaller size is due to the plants being different varieties, or to the shorter outside growing season, I don't know.
