Dawn Redwood, a deciduous coniferous tree

 

Hi Thomas, Grace and Friends of H3LPs,

今哺日，以「食到老、學到老」个態度，撩大家分享「細紅杉」（Dawn Redwood)个基本常識，作對無（=可以不可以）? My bet is that most of you may not have seen this little redwood and have not heard about it in your life. Basically, there are three kinds of redwoods in the world: Coast Redwoods(海唇紅杉） in California and Oregon, Giant Sequoia Redwoods（高山紅杉） in Sierra Nevada mountains of Central California and Dawn Redwoods（細紅杉） in Central China. You may not also known that dawn redwoods is deciduous coniferous tree(落葉針樹）.These photos of a dawn redwood were taken in our local park in Columbia, Maryland where we visit at least once a week during this COVID-19 pandemic mess. Naturalists call this redwood  “a living fossil” while some other people say, “It’s an ancient tree from the “dawn” of time.” I personally call it 「細（小）紅杉」compared to two other big ones(大紅杉、中紅杉） in the sub-family.

紅杉有三種

兩種在美國加州

一種在中國內陸

三種紅杉中

海唇紅杉大又高（=Coast Redwoods)

高山紅杉大又粗  (=Mountain Redwoods)

細紅杉又細又矮（=Dawn Redwoods)

細紅杉特色

入秋針葉變暗紅

最後歸樹光禿禿

這叢細紅杉

生自一粒細種子

到今大約八十年

As you notice in one of photos, this particular dawn redwood came from the seed in 1944.
