"Potentilla will show late and form flower buds again if you deadhead," he added. "They might rebloom even if you don't trim them back, but they will look a little scraggly."
Risbara, Bate and O'Donal also recommended roses, but not the old roses that cause so much trouble.
"The new 'Home Run' roses are in competition with the 'Knockout' roses," Risbara said. "They are very similar, they don't require much care, are resistant to the black spot and long blooming." O'Donal added Oso Easy as another brand of the tough landscape roses.
"There is new one from Bailey called 'Calypso' that has a unique apricot color," Bate said. "It's a compact variety and gets only a couple of feet tall and is a rebloomer, with blooms continuing right up until frost."
O'Donal and Estabrook both recommended caryopteris, or Blue Mist falsespirea as a good plant.
"It is bordeline hardy," O'Donal said. "You either have to protect them or treat them like a rose. If they die replace them if you like them."
Estabrook likes Hypericum, which has dark yellow flowers in midsummer.
Everyone recommended Clethra, although O'Donal thought it might be a little later than August.
It might be a little bit tall for every garden, but O'Donal really likes the catalpa tree.
"It's just about as pretty a tree as you can get, and it should be in bloom (in early July)," he said. "But not every garden can handle a 60-footer."
