    It looks like Ailanthus altissima or tree of heaven. The leaflets have 2 small asymmetrical lobes at the base and distinctive samaras. Now in British Columbia too. Your photos are excellent. Thanks for the exercises. Great fun!

      Eva, nice try — but “no.” Actually, Ailanthus altissima was the featured plant as Mystery Plant 008. If you look at that post, you can see the difference between the seed pods of Tree-of-heaven and this mystery plant.

      There is another blog post comparing Ailanthus altissima with a “looks similar” plant. You can find both posts by searching on “ailanthus” in the search box.

    This looks like a golden raintree, Koelreuteria paniculata. Discovered my first one this year because of the seed pods.

    • Angelyn says:

      Hurrah, Kari! You are correct. This is Goldenrain tree (Koelreuteria paniculata). This plant was a tricky one for me to figure out when I first saw it. In fact, it took nearly a year of watching it through the seasons — plus some serendipity — to find its name.

        Me too! I guess I just assumed it was a chinaberry until the seed pods showed up. I found it on a popular hike and bike trail on Lady Bird Lake here in Austin. Love the mystery plant challenge; keep ’em coming!

    Thank you!!! I have been frustrated in not being able to pin down the origin and name of this tree for numerous years. I live at an elevation of 5600 ft in Arizona, and have nursed this tree for 20 years to get it to 30 ft high with a 24 ft canopy. A most excellent shade tree for the hot summer sun! Hummingbirds love it! Cats too!

      I have a golden rain tree at my newly built home in Hollister Mo there were 2 but one was dozed. Hummingbirds don’t seem care about it, and there are quite a few here.
      One thing the description doesn’t mention is the color of seed pods. They are very interesting, they look as if polished bronze after being green as in the photos. It’s kind of small for being much good as a shade tree. This site was very helpful and fast thank you .
