A dark-leafed coleus would last well.

Thanks! Coleus is a good idea. I will get some next summer. Someone suggested Little Devil Ninebark. I am going to look for that also. I just love hydrangea. I have used them in bouquets and now I am drying some.

I saw a very pretty arrangement at Kroger's with hydrangea blooms and other plants' blooms that were all yellow. Not sure if they were using premature hydrangea blooms that normally look yellow as some do or if they applied die to the hydrangea blooms to absorb the yellow color though. The arrangement had a very nice Wow! factor.
