Anyone have any ideas for what to plant under in and around spreading wave petunias? The reason I want to do this is that in the summer when it's hot and dry, the petunias get ragged looking, and I was thinking that if I planted something else compatible with them that loves hot, summer weather the latter would come thru and shine during that time, and keep my bed looking great all the way til fall. The petunias are purple so a compatible color would be needed. They are also in partial shade in the afternoon so a less-than-full sun plant would be good. Was thinking maybe ganzias, but they might be too low. Thanks for any ideas!!!

i love to mix it in under my taller plants.
and even though its listed as an annual,mine seem to reseed every year.
ill go out and turn the soil and plant what i want and soon ill see the little red and green seedlings come up,nice little understory effect.
