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.
