I always have a patriotic veignet. I have 3 potted plumies that I place close together and I underplant with red/white/blue. One has white bacopa, another has blue petunia and the third has red calibrachoa. It is really nice. The petunias do get ratty by summer's end and I simply replace for a nice autumn display.
My patriotic garden happened by accident. We have only a small area by the gravel parking lot
that is dry, light, meager soil in full sun. It's a long, narrow strip that I plunk sun-lovers in without
a whole lot of planning. There in a row by accident are Alaska shasta daisy, bright red beebalm
and self sowed blue larkspur. I made two bouquets (not arrangements) for church yesterday.
