I must admit - I love Tardiva Hydrangea.
Hydrangea paniculata 'Tardiva' is a loose, carefree shrub that defines exuberance. It is one of the panicle hydrangeas that received a 2010 Cary Award for Outstanding Shrub for New England Gardens.
It adapts easily to many situations, blooms late in the summer which extends the garden season into October and can be pruned as a small tree if so desired.
I prune Tardiva in very early spring, leaving just a few buds on the stem - this ensures larger flowers on stiffer branches.

They also make a wonderful dried cut flower.
In the photos shown here from one of my landscape projects you can see that I planted Tardiva in front of a red barn building.
I also have white deutzia, white Siberian Iris, boxwood and nepeta 'Walkers Low' in this bed. What a show all season long! I fill in the spaces with white white angelonia, brunnera and lantana.
