When I am in the Australian garden in the Los Angeles Arboretum, I often smell very fragrant flowers, such as eucalyptus, in the springtime. I will also see some special plants. Walking into the garden in mid-February, I saw the bright yellow Acacia decurrens from afar. It was very spectacular. When I approached it, I saw the flowers like small balls of yarn hanging on the tree and they were very cute. Acacia decurrens, commonly known as black wattle or early green wattle. It is native to Australia and introduced to many parts of the world as an ornamental, shade, firewood and shelter, but mostly for its use in the tannin dye industry. The flowers are used to produce yellow dye, and the seed pods are used to produce green dye. The flowers are edible and are used in fritters. An edible gum oozing from the tree’s trunk can be used as a lesser-quality substitute for gum arabic.
我在洛杉磯植物園的澳大利亞園區，春天常會聞到很香的花香味道，例如尤加利。也會看到一些特別的植物。二月中走進園裡，老遠就可以看到鮮黃色的線葉金合歡，非常壯觀。走近看到一粒粒像小圓毛線球的花掛在樹上，很可愛。線葉金合歡，俗名為黑荊樹或早綠荊樹。它原產於澳大利亞，作為裝飾、遮蔭，柴火和遮蔽物，被引入世界許多地方，但主要用於單寧染料工業。花用於黃色染料，種子莢用於綠色染料。它的花是可食用的，用來做油炸餡餅。從樹幹滲出的可食用樹膠可用作質量較差的阿拉伯樹膠替代品。
