When things (in the vegetable world) have displayed their luxuriant growth, we see each of them return to its root.

夫物芸芸，各复归其根。

We look back upon the weak and minute stem on which this luxuriant growth depends, and ask, Can it be possible that such a capacity has a foundation so small?

我们回头看看这枝繁叶茂所依托的那根细弱的茎干，难道这样的根基这么小怎么可能？

But, in the meantime, eliminating all this complicated question of climatic change, the plain fact remains that the present rain and snowfall is abundantly sufficient for the luxuriant growth of sequoia forests.

但是，与此同时，撇开所有这些复杂的气候变化问题，显而易见的事实仍然是，目前的雨雪足以让红杉林茂盛生长。

Being a very tall one, and of luxuriant growth, it had been propped up against the side of the house, and was literally covered with a rare and very beautiful species of white rose.

它非常高大，生长茂盛，靠在房子的一侧，上面覆盖着一种稀有且非常美丽的白玫瑰。
