Unshiu citrus? Won Shu? Oonshiu? Satsuma?

In February 1986, at the Kato Memorial Garden, Don Dillon,  Four Winds Citrus nurseryman and Fremont city councilman, gave a dedication. His prepared notes said that "James Shinn, a prominent nurseryman, lived here and began a relationship with Japan by importing Japanese plums, persimmons and Unshiu oranges, some of which can still be found behind the Ozumia [azumaya]. He also brought in the beautiful Japanese maple located in the front of the garden. This happened in the period 1860 and 1890."

The maple died in 1994, but there are there are still two trees in the garden behind the azumaya, of unknown age. Are they Unshiu?

Flying Dragon

Looking very Smaug-like

Visitors at Shinn Park often ask about one particular plant - the flying dragon hedge (Poncirus trifoliata). The hedge that surrounds the Japanese garden is quite eyecatching. "What IS it?" they ask. "Can I eat the fruit?"

Poncirus trifoliata (aka trifoliate orange) is from Northern China and Korea. The original plan by Mai Arbegast specified a "solid hedge of plant such as Poncirus trifoliata to enclose garden...." to discourage dogs and trespassing. This unusual pointy feature of the garden really does encourage the use of the three gates into the garden. You only get stuck in it, or by it, once and then you avoid it.

The flying dragon fruit can apparently be eaten (or it might be poisonous according to one source), but the recipes given make it sound fairly unpalatable. My favorite recipe for a flying dragon citrus drink is "One fruit, five barrels of sugar, and five barrels of water".  A "barrel" is a somewhat loose measurement and can be somewhere between 26 and 53 gallons. But you get the idea. Needs dilution.

A good review of its uses are here. (Always double check your sources when trying something new!)

Big Sigh...Poncirus trifoliata is now Citrus trifoliata.
