Balliol's Poncirus trifoliata
by the library window
Balliol College Poncirus trifoliata flowers close-up
In a rather gloomy corner of the library wall, and overshadowed by an evergreen Azara microphylla tree, this Poncirus trifoliata is a tall, open and somewhat wispy-branched specimen. Part is growing up through a neighbouring Euonymus shrub. Probably never trimmed, it is amazingly different from the plants I photographed recently in Turin. Compare here!

When I visited in early May, the flowers were just opening, mainly towards the top, but clearly this is a large-flowered form.
The plant was listed in the 1973 catalogue of
Balliol College garden plants, so is probably over 40 years old. (The
2000 version of the catalogue is no longer on the college website, so I have made it available as a pdf download.)

Balliol's gardens are open to the public most afternoons, and are well worth inspecting for their diverse range of plants - many rarely seen in Britain.
