Between August 2009 and August 2010 the Union Bay Natural Area chalked up 2,050 volunteer service and educational tour hours from student organizations, University of Washington dorm residents, local community groups, the UBNA service corps, and University of Washington courses.  There are numerous opportunities to get involved with the UBNA this academic year through the courses offered as a part of the Restoration Ecology Network, the Society for Ecological Restoration student guild.

Probably one of the most elegant of all late summer to fall blooming perennials, this hardy begonia has been loved and admired by many avid gardeners since plantsman, Dan Hinkley, brought it back from Japan in 1997. It is somewhat late to emerge in the spring and it grows from a hardy tuber. The large, almost succulent leaves and stems provide a backdrop to airy inflorescences that dance in the breeze and soft pink, bubble gum flowers have a very faint, but pleasing fragrance. 

I can’t believe summer is almost officially over. What a seesaw of a season we had! Cooler than normal average temperatures, a few heat waves; nothing really stuck around long enough, and bloom time on some of the plants his year was really all over the place!
Oh well, it has been a busy and hectic summer that seemed to almost get away from us from time to time, but the plants can always be expected to put on a show for all to see and we take great pride in showcasing some of the best for the Pacific Northwest.
