香港木油桐花樹 wood-oil tree – tung blossoms – in hong kong

2012年4月寫過九龍公園的桐花,這兩年到了這時節(台灣媒體、旅遊推廣都鬧著“桐花節”的季度)都見該文章閱讀率高升。湊巧上星期在兵頭花園「發現」有棵木油(從前看不到樹牌,以為那是梧桐樹)。對這植物再了解的興致隨之炒高。

one of the biggest individual flower festivals in taiwan is happening right now. it is the tung blossom festival. as taiwan is getting really hot among hong kongers in recent years, more people is aware of this plant. i seem to benefit from this increasing awareness. i first met this plant in kowloon park two years ago at the best time of the year. the blog post i wrote afterwards shoot up in page view around this time of the year in 2013 and this year as well.

then earlier this month, i found another wood-oil in the botanic garden.

so i decided to learn more about this plant.

wood-oil

歸納網上資料,油桐屬下有三個種:

  1. 日本油桐
  2. 油桐 / 三年桐
  3. 木油樹 / 千年桐

香港主要是第三種。九龍公園和動植物公園各一顆桐花,都是千年桐。

參考台灣桐花祭網站,她們油桐木油桐都有,但也以後者較多。

there are three species under the genus vernicia, commonly called tung or tung-oil tree. they are

  1. vernicia cordata – native to southern japan. common name is japanese tungoil tree
  2. vernicia fordii – native to southern china, burma, northern vietnam. commonly known as tung-oil tree
  3. vernicia montana – native to southern china, indo-china. common name is wood-oil tree.

what usually seen in hong kong is no.3. one of its chinese common names is thousand-year tung. that points out the longer vitality, compare to vernicia fordii with a chinese common name of three-year tung.

in taiwan, both fordii and montana are common there. yet the latter are of larger number as well.

看植物,最吸引是賞花。但不要忽略其他特色趣味。木油樹和油桐可愛的地方,還有其巴掌大的心形或三、五裂葉片,葉基有一對杯狀腺體。

obviously the blossoms of wood-oil and tung-oil are gorgeous. but other parts of these plants are interesting too. i particularly love the leaves their beautiful shape as well as the two cute cup-like glands at the base of the leaf.
