两年生植物

This is a biennial, and one of the most useful pasture plants we have

这是两年生植物，也是我们最有用的牧草之一。

It occurs, for example, in annual and biennial plants and plant organs such as internodes.

发生在一年生或两年生的植物或类似节间的植物器官中。

European biennial formerly grown for the blue coloring matter yielded by its leaves.

欧洲两年生植物，原来用于提取染料的蓝色物质。

Although not quite as permanent as perennials, many biennials re-seed themselves, becoming comparable in performance to perennials. Biennial seeds that are planted one year will not flower until the following year. Foxglove, Hollyhock and Iceland poppy are biennials. Many people think of Hollyhock as a perennial as it self sows easily.

虽然没有那么长期稳定，很多两年生植物能够自我繁殖生长，这个是能够跟多年生植物相提并论的地方，两年生植物的种子在第一年播种种植之后并不会开花直到下一年，毛地黄、蜀葵和冰岛罂粟是两年生植物，许多人把把蜀葵当作多年生植物，因为他自我繁殖非常容易。

For the nobler plants are valued for the fruit they bear at last in the air and light, far from the ground, and are not treated like the humbler esculents, which, though they may be biennials, are cultivated only till they have perfected their root, and often cut down at top for this purpose, so that most would not know them in their flowering season.

因为那些更高贵的植物的价值是由远离地面的、最后在空气和日光中结成的果实来评定的，而不是像对待那低卑蔬菜的那样。蔬菜就算是两年生的植物，那也只是被培植到生好根以后，而且常被摘去顶枝，使得许多人在开花的季节都认不得它们。
