Our hibiscus is blooming gloriously, and our dahlias are doing well despite having been planted later in the year than was ideal. I just posted some photos of the flowers in my flickr site, in a new category just for flowers, which you can reach by clicking here.

I love dahlias but the only thing I seem capable of is killing them.
Tracie says that she had somewhat mixed luck with dahlias in Oregon because of the rain, i.e. sometimes their tubers rot if the ground stays wet for long periods of time.
