Invasives, not invaders. On a walkabout in the port city of  Jaffa in Israel, I noticed an invasive tree commonly seen in DC – that’s the Ailanthus altissima, also known as the stinking sumac tree.

Ailanthus was introduced in Israel in the 1920s by the British and was used extensively in urban gardening because it grew rapidly. What made it popular – rapid growth – also made it invasive.  It grows everywhere, crowding out native species and causing damage to infrastructure such as roads and sidewalks.

Although the ailanthus has 43 fans on Facebook, it’s still a stinker.
