Photos of the Poncirus trifoliata at Leatherhead Crematorium garden, Surrey, England. Taken with flowers just opening, 6th May 2001.
This is certainly the most magnificent specimen I have seen in the UK. It was covered in thousands of flowers.
I would guess the plant is about 3 metres high and about the same in diameter. The dual trunks (see photo) are each about 10 centimetres across.

I re-visited this site in early November 2001. Despite having been trimmed back somewhat, it was carrying a good crop of ripe fruit, up to 5.5cms diameter. The robin was feeding on blackberries growing up through the Poncirus shrub. The fruit contained many seeds which were made available through this web-site.
The final picture shows the very disappointing number of seeds collected in 2002. Just three seeds from eighteen fallen fruits!
