大葉欖仁紅葉季節 red-leave season of bengal almond

大葉欖仁冬天最美,在葉落完之前。

葉是大葉欖仁的主角。葉面大倒卵形,鈍圓葉端,葉基背有一對腺體,葉背脈腋有許多線窩。進入冬季,魔法展現。變紅變紫,綻放酡炫。

色彩豔麗,而樹本身多才多藝,耐鹽抗風抗污染。樹形、樹根都有獨特風貌。樹冠層傘形,側枝輪生。年月增長,樹冠開始向橫發展。老樹根有板根。

bengal almond is a beautiful tree. it holds upright and its horizontal branches are in tiers like a well-structured pretty gown.

leaves shed in winter and they always deliver a colourful final act . the big, broad, ovoid leaves are dark green and leathery in their prime. in winter they turn yellow-brown then red or deep burgundy before before saying good-bye.
