Tree-of-heaven (Ailanthus altissima) 臭椿
I believe almost everyone have seen it. Such common tree almost everywhere in the world. It is a fast growing, invasive tree. It is so weedy and also has foul odour. It is very difficult to get rid of it, so I hope people can weed the seedlings out.
But it is still has its purpose: medicinal uses and breeding ground of Ailanthus silkmoth (Samia cynthia).
Very hardy, it can grow in any full sun to partial shade location. USDA Zones:5-8. Mature size:50′-80′(H) x 40′-60′(W). Self seed easily.
生長快速的雜樹之一,非常強勢. 能在全日照到半日照處生長. 植株有臭味. 當然它也不是一無是處. 它是有其藥用價值(收斂劑)和樗蠶(Samia cynthia)產卵的植物. 不過這樹很難清除,常常再長出. 希望人們在除雜草時能將小苗清除.
它非常強健,能生長在任何全日照到半日照的環境. 耐寒. 成熟株高約50-80呎,寬幅約40-60呎. 容易落子自行繁殖.
